    Aux Audio Routing redesigned to use flexible Port Steering, programming character changed to asterisk, various enhancements added. — summary by updatemystuff.com

    Source: arcomcontrollers.com

    Show release notes

    Feature and Operational Changes Major Revision Numbering Change To Match new RCP Release Aux Audio Routing command eliminated (*2100xxx).

    Aux Audio now uses Port Steering Functions (166- 169) for Port Routing.

    This allows for on-the-fly changes, making operation much more flexible.

    Added support for future RTC Daughterboard Macro Priority used to only work on Ports set to repeat.

    They now will work on any Port regardless of repeat or non-repeat.

    Removed software defined serial buffers (which frees​ up a ton of RAM space for the DTMF buffers) as the serial port hardware UART has its own buffers.

    Software ones are superfluous).

    Changed the pound (#) to an asterisk (*) that is used in programmed Meters, Meter Alarms and Courtesy Tones.

    This allows programming of these features from the phone line.

    When a Timeout condition is cleared, the controller will now speak "Repeater Timeout Cancel" so the user knows exactly what happened. (this message is sent out ONLY Ports defined as repeating) Removed requirement for separate programming command ("Half Dup​lex ID") in order to allow non-repeating Ports to ID.

    Now, simply set that Port's Initial ID Timer to 0 to disable.

    Otherwise that Port will ID.

    Fixed bug where CTCSS Encode didn't work properly during startup "Ready" announcement Added capability to set Clock to seconds.

    If only use hh: mm when setting Clock, seconds are zeroed to top of the minute.

    If use hh: mm: ss then seconds set to value.

    New feature added to allow interrogation of remote base frequency, offset and mode.

    To interrogate, simply enter the Remote Base Prefix with no argument.

    IE Remote Base Prefix = A7.

    So enter A7 and unkey Fixed Tail Message Timers which were broken in an earlier version Note: This firmware version requires RCP 5.28

    Improved timeout handling with courtesy tones, enhanced audio muting during commands, and Tail Messages now use Command Macros. — summary by updatemystuff.com

    Source: arcomcontrollers.com

    Show release notes

    Feature and Operational Changes Reworked Timeout rout​ines.

    When a Timeout occurs, Timeout Message is sent to proper Port.

    When Timeout is cleared, controller sends Courtesy Tone to inform users repeater is "back".

    Properly mute audio when Ports are linked and controller needs to speak.

    This means that even if a linked Port is active when you enter a command, that Port will be muted so as to properly hear any controller speech in response to that command.

    Changed Tail Me​ssages to call Command Macros instead of Message Macros.

    This allows for much more flexible messages.

    All Ports are automatically unlinked during RCP operations. 2 seconds after RCP operations cease, the previous Port linking status is restored.

  41. Version 4.63 Released Sep 27, 2006 First seen Sep 9, 2026

    Added DTMF evaluation control; fixed message macro delays and fan startup — summary by updatemystuff.com

    Show release notes

    Feature addition and anomoly correction When speech was sent to a Port that wasn't already transmitting and that speech consisted of more than one Message Macro, Tx Delay was i​nserted which caused long delays between Message Macros.

    That is now fixed Corrected bug in Kenwood G707 code where memory recall didn't always work on the first try.

    Correct bug where fan didn't start if all Ports were in non-repeat mode and Autopatch was used.

    Added new feature which allows control of DTMF evaluation on either COS o​r CTCSS closure.

    This can be helpful if your squelch locks open and may be selected on a Port-by-Port basis Note: This firmware version requires RCP 5.04

    Show release notes

    Feature change and bug fix Allow control of Port Timeouts based on link status Fixed a bug w​here runtime memory was being overwritten if a timeout occured and Ports were linked.

    This resulted in a linked Port not always having its full 2-way link status restored, which didn't allow that Port to transmit after a timeout, until it was relinked.

    At times, it was possible for an unlinked Port to be supplied the​ receive audio from another unlinked Port (some users reported this as "crosstalk").

    This was also caused by a bug that would intermittently overwrite runtime memory Note: You MUST use RCP 5.0.3 for firmware version 4.5.6 and later

    enchanced ID and CTCSS encode operation and new featu​re additions When a port needs to ID, the other port(s) no longer just "hang" until the IDing port(s) finishes, although there will be no courtesy tone.

    Normal hangtime will now work.

    Added new ID function to allow a port programmed as half-duplex to still ID.

    This is useful for IDing links.

    The normal ID rules (speech/no speech IDs, Initial and Pending ID Timers) apply.

    If a port is programmed to repeat, this setting it ignored.

    Added radio memory recall capability when using Kenwood TM-V7A or TM-G707 for a remote base radio.

    Up to 255 memories may be recalled (these are the memories stored in the radio, not in the RC210 memory) Fixed bug in TimeOut routine, where time out message didn't speak correctly.

    Now if a user times out, the controller will speak "Repeater Time Out" and then drop that port's transmitter until user unkeys.

    CTCSS Encode timeout may now​ be selected to start on closure of COS or upon completion of Courtesy Tone.

    This allows for much more flexible timing, such as accurately emulating "chicken burst".

    Show release notes

    many enhancements and improvements have been implemented.

    Included is a new utility to automatically reorganize memory.

    Please read the included README file for details on installation.

    Courtesy tones now work 100% reliably.

    There were some times where they wouldn't play when they should and played when they shouldn't.

    It was also possible for them to be sent to the wrong port under some circumstances.

    Under so​me circumstances, it was possible for an ID to be sent to the wrong port.

    Timers that were programmed in minutes weren't always all that accurate.

    In some cases It was possible for them to be off by as much as a minute.

    They are now accurate to within ± 1 second.

    Courtesy Tone #9 now defines what is played if someone unkeys on the "next" port, if your current port is linked to the next port (this is explained below).

    Courtesy Tone #10 now defines what is played if someone unkeys on the "previous" port, if your port is linked to the previous port.

    Either Voice or CW IDs may now be selected to be used as the Pending ID.

    There is a new timer that looks for receiver activity during the past X seconds and, if no activity has occurred a Voice ID will be used.

    If there was activity during this time, a CW ID will be used.

    You may also force Pending ID's to ALWAYS be either Voice or CW.

    You may disable Voice ID's completely, in which case all ID's will be done in CW.

    Voice ID message length has been increased from 10 words to 22 words.

    Vocabulary or DVR tracks may be used in any combination.

    CW ID length remains at 15 characters each. "ID Extras" have been added, allowing the use of various 'run time' variables in ID messages, such as Good Morning/Afternoon/Evening, the time of day and the date.

    Placement is selectable (before or after a Voice ID) or may be programmed to be a random selection.

    You may now specify that ID speech be interrupted by a signal appearing on a port or mixed with that signal.

    If interrupted, the ID automatically reverts to CW.

    This can now be done independently of other speech messages.

    It was not possible to interrupt a playing DVR track before.

    It will now interrupt based on one of three scenarios: All Alarm inputs are now debounced (you can program the amount of time used for debouncing) to eliminate false triggers due to noise on the line.

    Kerchunk filtering on each port is now fully programmable.

    In other words, you can program how long it takes for a signal to be considered valid.

    There are now 40 new Message Macros, each may store up to 10 vocabulary words and/or DVR tracks.

    These are used in Command Macros You can now program the CW tone for each port to be dual tone.

    It can still be programmed as a single tone if you want.

    There are now 20 DTMF Memories; each one can store a sequence of up to 10 digits and send DTMF out any port on command.

    A rece​iver may now be disabled, in which case the transmitter for that port will remain active for all other activities.

    This differs from the existing Transmitter Enable/Disable commands.

    Support for the Doug Hall RBI-1 Remote Base Controller Command Macros now have priorities, allowing you to specify whether or not it should be interrupted by some other activity.

    Command Macros can be restricted to only work from any combination of Ports.

    There are now a total of 90 Command Macros.

    The original 40 are the same as they've been - capable of storing up to 15 functions and an additional 50 "Short" Command Macros that can store up to 4 functions, which are mainly used for remapping of functions.

    No more command codes "hanging out in the open".

    Only those functions you specifically map to be available, are available without first unlocking a Port.

  80. Version 3.55 Released Oct 8, 2003 First seen Sep 9, 2026

    Timeout timers now program in seconds instead of minutes, with per-port DTMF control and macro renaming. — summary by updatemystuff.com

    Show release notes

    fixed some bugs and added/changed sever​al features Lots of little "tweaks" to improve overall performance Fixed bug in Port Activity timers, where they didn't time accurately Fixed bug in CTCSS Encode, where it didn't track COS properly Timeout Timers now program in seconds instead of minutes DTMF may now be disabled on a per port basis.

    When disabled, that port will only respond to the Enable command or Macros 35 - 40.

    This allows a port to monitor a comwork backbone and ignore most commands.

    By allowing certain macros to be called when DTMF is disabled, it is possible to link/unlink that port without allowing access to other commands from that port DTMF access may now be selected on a port-by-port basis, to require CTCSS or not require CTCSS Alarms changed.

    They no longer call their own unique speech messages but rather may be programmed to call a macro or an Auxiliary Audio Input.

    This provides much greater flexibility The ability to play any voice or CW ID from within a macro Unlock codes may be reset to factory default without affecting any owner custom programming Moved port assignments for speech from the scheduler programming to macro programming, since the scheduler calls macros in the first place Ability to rename macros (you can now assign custom command codes to each of the 40 macros) Fixed bug where courtesy tones didn't a​lways wait for current command acknowledgement before being sent Fixed bug in CW speed selection where the cw speed wasn't always accurate Fixed bug in courtesy tone delay time.

    Sometimes the programmed delay wasn't accurate Added capability o reset the unlock code without wiping out all custom programming by installing a temporary jumper on Port 3

    this version incorporates the new auto-detect UpdateEram, which you need to load first.

    Please read the rc2103_52.bas fil​e for full details before installing this update.

    New initialize automatic management.

    Starting with Version 3.51, you will no longer lose custom programming (included in the zip file) Added macro erase command Added DTMF Mute/Covertone timer Added controller reset command, which also doubles as verify that the watchdog timer is working properly Revamped Courtesy Tone programming and assignments.

    They are now 1 - 10.

    Added optional port command to Scheduler programming.

    It is only needed to indicate to which port a speech message should be directed Added Scheduler "don't run next time" functions to better manage reoccurring messages (such as saying the time every hour) Added Weekdays and Weekends to S​cheduler days of the week parameters Added Calendar function - you can recall today's date on command or use it in a macro Did more work on DTMF buffering.

    You can now enter up to 50 DTMF digits commands at one time, separating commands with a "D" and the controller will execute them in order.

  82. Version 3.1 Released Aug 11, 2003 First seen Sep 9, 2026

    DTMF can be entered while IDs play; fixes for macro recursion, ID bugs, and linked port operation. — summary by updatemystuff.com

    Source: arcomcontrollers.com

    Show release notes

    There is no need to use Initialize.zip, just download and install this update Revamped macro routines to prevent recur​sive looping when calling other macros Macro 1 being run at startup now works only if Macro 1 has actually been programmed.

    Fixed bug in ID routines.

    Initial and Pending IDs now work as stated in the manual Fixed bug where when ports were linked, CW ID inexplicably stopped midstream Changed DTMF routines to take​ advantage of hardware interrupts.

    This means you may now enter commands without having to wait for IDs or speech to end Fixed courtesy tone assignments Fixed link keyup, where there was a delay while waiting for courtesy tone to start Updated manual to reflect changes.

    Included new files in update zip file that allow much simpler programming of controller when uploading updates

  83. Version 2.5 Released Aug 5, 2003 First seen Sep 9, 2026

    DVR revamped with 20 tracks and editing, Speech Override behavior changed, auto-relock timer added. — summary by updatemystuff.com

    Show release notes

    You will need to download Initialize.zip, install it, then install the new firmware (a link to FirstTimeInitialize.zip may be found at the top of this page) Added unique courtesy tone wh​en one port is linked to another (makes it easier to identify from which port a signal is being heard) Corrected where if a port was in half duplex, it had hangtime when another port linked to it Modified how Speech Override works.

    If OFF, speech is mixed with receiver audio.

    If ON, speech is stopped when a signal is received.

    If that speech is an ID, the voice ID reverts to CW in order properly identify Talking over Voice or CW IDs now works correctly Added programming timer.

    If controller is unlocked and there is no DTMF for 2 minutes, the controller automatically relocks.

    Completely ​revamped the DVR routines.

    Added a total of 20 tracks and editing commands to allow squelch tails and other noises at the end of a track to be edited out.

    Added readback of available recording time left.

    Corrected bug in analog meters and removed internal voltage reference.

    Revised manual to reflect the above changes, as well as added much more detail about installing firmware, along with many screenshots of the actual program.
