Table 5: DIP Switches 5 through 9
Switch State Function
5 ON Enable auto Fallback Mode after detecting an intercept error.1
OFF Disable auto Fallback Mode after detecting an intercept error.
6 ON Hang-ups do not cause Fallback Mode.
OFF Third hang-up without receiver ACK causes Fallback Mode.2
73 ON 240 sec poll
OFF 75 sec poll
8 ON C900 sends initial handshake to panel after 6 sec dialing break.
OFF C900 sends initial handshake to panel after 1 sec dialing break.
9 ON Enable Anti-Replay/Substitution.4
OFF Disable Anti-Replay/Substitution.
1 If an error occurs in the Intercept Mode, the C900V2 automatically returns (falls back) to the telco line.
2 If the receiver does not acknowledge a report intercepted by the C900V2 in the specified time, the digital dialer
hangs up and retries the message transmission. The C900V2 switches to Fallback Mode based on the number of
hang-ups.
3 The time that elapses between polls from the C900V2 when it is idle (not expecting a dialer acknowledgement).
4 This DIP switch must be set to ON if the receiver is set up for NNC Mode.
Any error forces the C900V2 to switch
to Fallback Mode (phone line backup)
for 2 min the next time the control panel
seizes the line (if DIP Switch 5 is ON,
DIP Switch 6 is OFF, or both, and if the
control panel seizes the line within 2
min). Intercept errors are always
reported to the receiver. If the receiver
does not acknowledge a signal
intercepted by the C900V2 in the
specified time, the control panel digital
dialer hangs up and tries to send the
message again.
3.3 LEDs
The C900V2 has two dual-color status LEDs: the
system LED and the dialer LED.
The Ethernet connector also includes two LEDs
that indicate the status of the network connection.
The right LED lights or flashes when there is a
valid connection to the network.
3.3.1 System LED (LED 1)
The system LED indicates the status of the
receiver and the C900V2 itself. Refer to Table 6 on
page 11.
3.3.2 Dialer LED (LED 2)
The dialer LED indicates the status of the digital
dialer interface. Refer to Table 7 on page 11.
