Viking RC-3 Technical Practice page 3

NORMAL MODE: The RC-3 is running in the Normal Mode anytime dip switch 4 is set to off to disable the E-30 Mode. In the Normal Mode,
default relay commands exist but custom relay and global commands of one, two or three digits in length can be programmed. When dip switch
2 is set to on, "Q" plus a one to six digit access code must be dialed before relay commands can be entered.
PARALLEL CONNECTION: The Parallel Connection allows the RC-3 to be "parallel" connected to a phone line (or talk path) and detect touch
tones to control relays, when the device using the line is not connected to the "Output" side of the RC-3. Ideally, the phone line or talk path is
passed through the RC-3 from "In" to "Out", so the RC-3 can use it's Loop Detection to determine when the line is in use or goes back to idle.
The Parallel Connection allows the RC-3 to function properly in the cases when it is not possible to wire all devices that share the line through
the "In" and "Out" of the RC-3. To use the Parallel Connection, tap off the phone line or talk path and connect it to the "In" side of the RC-3 and
set the Talk Battery switch to OFF.
PROGRAMMING TIMER: The Programming Timer is a 20-second timer that runs when remote programming is entered by calling in to the RC-
3. Every time a touch tone is entered, the timer is reloaded, so it is possible to stay in programming as long as at least one touch tone is entered
every twenty seconds. If the timer elapses, the RC-3 gives three beeps and hangs up.
RELAY COMMANDS: These are user-programmable touch tone commands that tell the RC-3 to turn the relays on or off, start a timed closure,
or indicate status. The default values for the Relay Commands are listed in the Programming section.
RELAY CONTROL STATE: The RC-3 is in the Relay Control State when access code is enabled (dip switch 2 ON) and "Q" plus the correct
Access Code has been entered. Once in this mode it will respond to Relay Commands. The RC-3 leaves the Relay Control State when the
Access Timer elapses (Ring Trip Connection or Parallel Connection with Access Code enabled) or when the user hangs up in Trunk Connection
or Series Connection. Similar to the Unsecure State but in the Unsecure State the Access Timer does not apply.
RING TRIP CONNECTION: In the Ring Trip Connection, the RC-3 is connected to a CO line or analog PABX/KSU station. Talk battery is pro-
vided by the CO or PABX, so the RC-3 talk battery switch should be turned OFF. The CO or PABX rings the RC-3, which answers after the pro-
grammed ring count and can then provide relay closures.
SECURE STATE: When access code is enabled (dip switch 2 ON) and "Q" plus the correct access code has not yet been entered, the RC-3 is
in the Secure State. In this Secure State, the RC-3 ignores all other touch tone dialing except "Q" plus a match to the Access Code to access
the Relay Control State or "Q" plus a match to the Security Code to access the programming mode.
SECURITY CODE: The Security Code is a six-digit touch tone code used to enter programming. Once the code has been successfully entered,
any of the programmable features can be changed. It is recommended that the default Security Code of 845464 be changed to a unique code
by the user in programming. See Programming.
SERIES CONNECTION: The Series Connection is when the phone line or talk path is passed through the RC-3 from "In" to "Out". The RC-3
then uses it's Loop Detection to determine when the line is in use or goes back to idle. Once the Relay Control State has been accessed, the
user remains in the Relay Control State as long as the loop is still detected. The Access Timer and Programming Timer are not running in the
Series Connection.
TRUNK CONNECTION: In the Trunk Connection, the RC-3 is connected to a trunk input of a phone system or phones dedicated for relay con-
trol. The RC-3 provides 32V of talk battery, and the unit is accessed by just going offhook on a connected phone or accessing the trunk input.
The Access Timer and Programming Timer are not running in the Trunk Connection.
UNSECURE STATE: When the access code is disabled (dip switch 2 off), the RC-3 is in the Unsecure State. In this mode, the RC-3 continu-
ously monitors touch tones and acts on any match to a relay command it detects, even if they are preceded by or followed by other touch tones.
The Access Timer is not running in the Unsecure State.
