Table 20: C900TTL-X Dialer Format Settings – Dipswitches 1 - 4

Dipswitch positions 5 through 10 (Table 21) set up the C900TTL behavior, based upon the application. See the

notes below the table for more information. (The switch positions will be referred to as DS-5 for Dipswitch 5, etc):

Switch and Condition APPLICATION

DS-5 ON Enable AUTO FALLBACK condition after detection of an intercept error

DS-5 OFF Disable AUTO FALLBACK condition after detection of an intercept error

DS-6 ON No number of hang-ups will cause FALLBACK MODE

DS-6 OFF Third hang-up without D6600 or host computer ACK causes error.

DS-7 ON Default 240 second poll of D6600 or host computer during idle state

DS-7 OFF Default 30 second poll of D6600 or host computer during idle state

DS-8 ON C900 will send initial handshake to Alarm Panel after 6 second break in dialing

DS-8 OFF C900 will send initial handshake to Alarm Panel after 1 second break in dialing

DS-9 ON Unused

DS-9 OFF Unused

DS-10 ON 9600 BAUD data rate from C900 to onboard Network interface

DS-10 OFF 1200 BAUD data rate from C900 to onboard Network interface

Table 21: C900TTL-X Dipswitches 5 – 10

Note: Several errors can occur in the intercept process. Any error will force the C900TTL-X to switch the Alarm Panel

dialer to the Fallback (phone line backup) position for 2 minutes when the Alarm Panel next seizes the line (if

enabled, and if the seize occurs within 2 minutes). Intercept errors are always reported to the D6600 Receiver. If

the D6600 Receiver does not acknowledge a signal sent that was intercepted by the C900TTL-X in the proper

amount of time, the Alarm Panel digital dialer will hang up and retry the message transmission.
