Installation Instructions

V3.7 Changes and Additions Description

Errata pages for original manuals

The IC's are static sensitive - keep them in their protective packaging until installing them.

Read the Installation Instructions and other documents thoroughly before proceeding.

We'd prefer general comments and feedback to be in writing. If you get into trouble, however, you can give us a call. Our Technical Support Line is staffed from 9 am to 3 pm Pacific time (except 12-

12:30), Monday, Wednesday, Thursday and Friday, at (408) 727-3413.

In order to minimize your long distance charges, and to avoid telephone tag, this is the only line available for technical support. You will not get a busy signal if no one is available to take your call,

you may leave a voice mail message, or you may try again later.

RC-850 Repeater Controller V3.7 Installation (from V 3.5 or V3.6)

Review these instructions and the manual errata sheets provided. Insert the errata sheets in your original manual binders. Remove your controller from service. Be sure that power is completely removed. If you have a backup battery, disconnect it, or at least be sure that the controller's power switch is off. Remove the four EPROMs at locations U8 on the main controller board, and at locations U15, U16 and U17 on the Computer Interface board. Place these in the black conductive foam supplied. Plug the new EPROMs provided into their respective locations on

the main controller board and the Computer Interface board. The External Device Busy and the VOX Logic inputs which shared a single pin are now separate. The Dial Tone Detector input has been eliminated to accommodate the separate VOX Logic input.

If you are using external VOX detector hardware: Move the VOX detector logic output from pin 19 of the Analog Input connector to pin 17 (formerly the Dial Tone Detect input).

If you are using external Dial Tone Detector hardware: The Dial Tone Detector input has been eliminated, and is redefined to be the VOX Logic input (above). Program pauses into the Patch Dialing prefixes to provide sufficient delay to dial tone.

You are now ready to turn the controller back on. Before doing so, double check that the new EPROMs are in their proper locations, that they are oriented correctly, and that there are no bent pins. Turn the controller back on. It should sign on saying "RC-850 V3.7," and possibly an initial ID.

Reprogramming

It will be necessary to do a small amount of reprogramming, since certain information is stored in the E2PROM non-volatile memory differently than in Version 3.6. Message Macros can now hold up to 22 characters each. They need to be reprogrammed using the message editor if you are using them in any of the controller's programmable messages.

Scheduler Macro Sets must be re-stored with the following new Control Op selections set as desired (see page 1 of "V3.7 Changes and Additions" for codes):

Individual User Access Codes Required/Not Required

Transmitter Turn-On Delay Enabled/Disabled

For each macro set used in your controller, select the macro set

manually, make the appropriate Control Op selections, and re-store

the macro set by unlocking and entering '*591x (x=0-9).

Check out operation of your patch, remotes, etc. to feel confident

that the system is working normally. This completes the installation and programming changes to

accommodate Version 3.7. You may now proceed to use the variety of new features of the software.

END OF INSTALLATION INSTRUCTIONS

 

RC-850 Repeater Controller V3.7 Changes & Additions 1/93

Items are organized by order of appearance in the manuals.

Access and Command Modes

Individual User Access Codes can be enabled or disabled (required or not required for access) with Control Op commands.

Root 1 Root 2 Root 3 Root 4

Enabled 277 467 747 007

Disabled 278 468 748 008

The Transmitter Turn On Delay can be enabled or disabled with Control Op commands.

Root 1 Root 2 Root 3 Root 4

Enabled 227 417 697 957

Disabled 228 418 698 958

 

Control Receiver

The control receiver (when Control Op enabled for on-air) now behaves as follows:

1. A mobile keying up the control receiver will interrupt speech messages (if Speech Interrupted by Carrier is Control Op selected).

2. A mobile through the control receiver can "click" to initiate patch dialing.

3. A mobile through the control receiver will refresh the Patch Activity Timer.

4. A mobile through the control receiver will key link and remote transmitters that are on.

When Touch Tone Access is Down, Control Op commands are accepted through the repeater receiver.

With the Repeater Receiver Disabled (Control Op), a touch-tone "D" entered through the repeater receiver will no longer cause the transmitter to key up with a hang time.

Identification

When a macro set is selected, PID2 was automatically selected at the same time. If the macro set was repeatedly loaded by Repeater Activity Timer timeout, the controller appeared to be stuck in PID2. This is changed to allow continued ID rotation.

 

Courtesy Tones

If a courtesy tone is programmed with "Delay to Segment 1" less than 82 ms the tone will generate properly.

Telephone Interconnect

Outgoing Calls & Autopatch

When Autodial numbers are loaded from the phone, the telephone control timer is reloaded automatically to allow continuous programming.

Autodial numbers can now be read back from the phone and from over the air. The command is:

[User Loadable Autodial Bank 0/1 /2 Load/Erase Prefix] * [two digit location)

Autodial numbers containing pauses can be programmed from the terminal with the "A" command using the * key on the keyboard.

Touch-Tone entered during "click pauses" and phone number dialing no longer cancel the patch (to eliminate abuse).

User Loadable Autodialer: The patch can no longer be accessed from links which are turned off (at the User level).

With "Dial Without Click" mode Control Op disabled, PTT will not drop briefly after the second pause.

It is no longer possible to accidentally load phone numbers into Autodial slots above 249 from the terminal using the "A" command.

Incoming Calls

Unanswered directed reverse patches leave mailbox messages properly in Reverse Patch Mode l.

Phone Number Macros

Touch-Tone * can be generated by the controller for use in Patch Dialing Prefixes, Phone Number Macros, and Leading 1 Override, by programming vocabulary code 73 (letter S) into the appropriate message.

Remote Phone Lines

If the repeater transmitter is defined as the Remote Phone Line Down Channel, the CTCSS encode output is now active during the patch up and down sequences to allow the receiver at the phone line to operate in tone squelch.

The same port can now be used for the Remote Phone Line Up and Down

Channels, allowing a single link transceiver to be used at the repeater, or

allowing linking to a simplex patch or another repeater.

The FC-900 Interface works properly with Remote Phone Line operation.

Remote Bases and Links

User Command Control

The crosslink off message is changed from "X" to "OK".

With an FC-900 band unit on in transmit, a mobile key-up while the controller is talking will not disable speech.

When Touch-Access Mode is down, enabled link and remote base transmitters will not key up.

The patch can no longer be accessed from links that are user level "off."

 

 

Command Acknowledgement

When frequencies are entered without * as a decimal point, the response "Frequency" is not interruptible by a mobile on the link so it will be heard.

In BCD mode (not FC-900 mode), when a new frequency is entered, the controller will say the programmable frequency prefix correctly.

With Link 1/2 BCD and 3/4 FC-900, the controller will say Link 3/4 prefixes and frequencies correctly.

The word "base" is no longer missing from certain programming commands.

Alarms

Alarms that occur when Touch Tone Access is Down leave a mailbox message properly.

Voice Response Telemetry

Analog Measurement

The number of Emergency Autodial calls is logged to VRT channel 30, and the count can be cleared using channel 62.

The "MPH" wind speed response is changed to "miles per hour."

Internal Datalogging Telemetry

The Period of Last Repeater Timeout (channel 31) can be cleared using channel 63.

Paging

When Touch Tone Access is Down, a paging command from the phone responds with "TT Down."

Demo Messages, Bulletin Board, and the Mailbox

Mailbox

Mail Present Message (MPM):

1. If the mailbox is empty, the controller will substitute silence correctly.

2. If programmed with a Morse message, it will play as Morse correctly.

3. If the mailbox is empty, a tail message containing the MPM is handled properly.

When the controller is reset, the day stamp on mailbox messages is not changed.

Computer Interface

The unlock timer is refreshed by every keyboard key press.

Autodial numbers programmed using the A (Autodial) command accept the * key as pause.

Certain rare keyboard entry conditions will not corrupt data in E2PROM.

 

 

Command Log

Entries in October, November, and December now date stamp properly.

When a remote base frequency change is entered, the command log does not add a bogus "ILJAC" command entry.

A VRT command consisting of VRT Prefix + Touch Tone "C" will not freeze the output of the command log.

Auxiliary Touch-Tone Decoders

The Auxiliary Touch Tone Decoders Sequence-to-End-of-Transmission Timer is changed to 8 seconds to accommodate long linked repeater hang times.

Control Operator Commands

Entering the "Don't Answer Phone Next Time" command from the phone no longer extends the two minute Telephone Control timer.

Programming Commands

Timers

The unlock timer is changed from l minute to 1 minute 45 seconds.

Messages

Message Macros 1-4 are expanded to hold 22 characters each.

DVR Interface

With the FC-900 and DVR, the first track of a programmable message plays properly when the remote base is on in transmit mode.
