D. Series Connection
In the Series Connection, a CO line or analog PABX/KSU station is connected to the IN terminals and a Viking entry phone or any other standard
analog phone is connected to the OUT terminals of the RC-3. The RC-3 can be accessed any time the entry phone is using the CO line or PABX
station. If the Access Code is disabled, the user has immediate access and can begin entering Relay Commands. If the Access Code is enabled,
the user enters "Q" plus the Access Code, hears two acknowledgement beeps, enters the Relay Control State and can start controlling the relays.
The Access Timer is not running in the Series Connection. The RC-3 leaves the Relay Control State when the phone or entry phone hangs up.
E. E-30 Mode
1. Setting up the E-30 Mode
To program the RC-3 to operate in the E-30 mode, just flip DIP switch 4 to the ON position. The RC-3 automatically programs the E-30 relay
commands and sets all three timed relay closures to five seconds. The E-30 Mode was designed to make the RC-3 and E-30 handsfree speak-
erphones fully compatible with one another when used on the same CO line or PABX/KSU station. This mode forces RC-3 commands to fixed
values that will not interfere with E-30 operation. The programming mode of either the RC-3 or the E-30 can be accessed remotely and RC-3
relays can be controlled during outgoing or incoming calls. Any programmed custom relay commands have no affect in the E-30 mode. The E-
30 mode is compatible with expanding to two or three RC-3's on the line. Relay bank number programming still applies for the second and third
RC-3 to change their relay codes. Since this mode of operation uses "Q" for relay control, "#" plus the valid security code must be used to access
the programming mode. The relay commands are two digits in length and are very similar to the default relay commands. The commands are
as follows:
Description
Activate relay (latch)
Deactivate relay (unlatch)
Timed activation (factory set to 5 seconds)
Interrogate relay status (one beep = deactivated, two beeps = activated)
To force the RC-3 to hang up
To start timed activation for all relays
Note 1: The relay numbers change from 1-3 to 4-6 when programmed to relay bank number 2 (2#54). The relay numbers change to 7-9 when
programmed for relay bank 3 (3#54).
Note 2: The Access Code can be disabled in the E-30 mode but this is not recommended when the E-30's are programmed to dial phone num-
bers or extension numbers.
Note 3: The RC-3 will not provide any error beeps when "#" is dialed or when "#" plus six digits are dialed that do not match the security code.
Note 4: The E-30 can not be programmed to dial a " Q " touch tone as part of a phone number (for example, programming the E-30 to dial " Q 67"
before the rest of the number to block caller ID data). The " Q " from the E-30 will set the RC-3 to the Relay Control State.
Note 5: Programming a pause as part of a phone number in the E-30 will set the RC-3 to the Relay Control State, since a pause in the E-30 is
programmed with " Q 7". If pauses are needed in the E-30 dial string, remove power to all RC-3's that are on the line while programming the E-
30's, then reconnect power to the RC-3's when finished programming.
Note 6: In the E-30 Mode, if you access the program mode of the RC-3 and attempt to program custom relay commands, custom global com-
mands or the access code, the RC-3 will provide three error beeps. Custom commands can not be programmed in the E-30 mode.
Note 7: When the RC-3 is switched into or out of the E-30 mode, the timing for "timed activation" of each relay is set back to five seconds. This
can be changed to any value up to 18 hours.
2. Operation in the E-30 Mode (Access Codes Enabled - Dipswitch 2 ON)
Outgoing Calls: When the button is pushed on an E-30, the E-30 starts dialing its programmed phone numbers. When the call is answered,
the user enters a "Q", they hear two beeps and can start controlling the relays. The Access Timer is not running in the E-30 Mode if the CO line
or PABX/KSU station is connected to the IN terminals and the E-30's are connected to the OUT terminals of the RC-3. If the RC-3 is wired in
parallel to the CO line or PABX/KSU station (nothing connected to the OUT terminals of the RC-3), the Access Timer will be running and will pull
the RC-3 out of the Relay Control State and provide three beeps if the timer expires (to reenter the Relay Control State it is necessary to dial "Q"
again).
Inbound Calls: Call the CO line or PABX/KSU station connected to the RC-3 and E-30's and an E-30 or the RC-3 will answer the call. They
can then enter the "Q", will hear two beeps and can start controlling the relays. Whether the Access Timer is running or not running depends on
how the RC-3 is connected, as described above in "Outgoing Calls".
F. Notes for All Modes of Operation
1. If the timed activation of a relay is disabled by programming "000000" (or blank) as the time value, the RC-3 will provide three error beeps when
a user in the Relay Control State or Unsecure State attempts to dial the timed activation command for that relay.
2. When custom relay commands have been programmed and a user in the Relay Control State or Unsecure State dials a custom relay command,
the RC-3 searches for a match to a programmed relay command starting at memory location "#10". If the digits dialed do not match the command
programmed in memory location "#10", the RC-3 checks memory location "#11" and continues searching from the lowest to the highest memory loca-
tion ("#42"). Once it does find a match to a relay command, it reacts to the first match found and does not search any further. If the same custom
relay command is programmed into multiple memory locations, only the command programmed in the lowest memory location will work properly in
operation.
