MONITORING
Test these features by shorting across the appropriate terminal
block pins, then check to make sure the associated relays activate
and deactivate properly. Once your wiring is in place, test the
functions again.
BUILT-IN MODEM
1. Call the first unit in the chain using a Hayes-compatible
modem hooked to a terminal (or PC using terminal
emulation software).
2. If connection is made, the "TRANSMIT MODEM DATA" (TX)
and "RECEIVE MODEM DATA" (RX) indicators should flash as
data is transmitted and received, and you should be able to
access the programming mode described in Other Special
Functions of the programming manual.
3. If connection is not made, ensure that the baud rates of both
modems match. If you have a 1100329 board it must be set to
300, 1200, or 2400 baud to communicate with the Infinity
system's 300 (or 2400) baud modem.
MULTIPLE ENTRY
1. Disconnect the telephone line from the system and try dialing
a number. If the system displays a
"LINE IN USE - PLEASE WAIT" message, this feature is
working correctly.
2. Reconnect the telephone line and the system should beep and
display the message: "LINE IS NOW AVAILABLE - PRESS # TO
TRY TO CALL AGAIN". Make a call or press the "*" button
until the welcome message returns.
NOTE: To ensure multiple entry use Programming Step 82,
option 4.
METHOD OF DIALING
1. The Infinity is factory set to use DTMF tone dialing. To change
to rotary (also called pulse) dialing, enter the programming
mode (see Programming Infinity Systems with Multi-Link
Firmware manua) and press "55" followed by "ENTER".
2. When the new programming prompt appears on the screen,
the change has been made. To change the method back to
DTMF tones, use the same procedure except substitute "60"
for "55".
CCTV MONITORING (OPTIONAL)
When the monitor or television is turned on, picture will appear. If
no picture appears, check the J1 connector on the CCTV power
supply board. Make sure the connector is firmly attached to the
power supply board.
