DIP Switch Settings

The LTC 8713 Series Alarm Port Expander
communicates with the Allegiant series main bay and
the LTC 8540/00 Alarm Interface Unit via RS-232
communications. The LTC 8713 Series Alarm Port
Expander contains internal DIP switches which can be
used to set the communication parameters. The cover
must be removed if the DIP switches need to be
changed from their factory default settings. See Cover
Removal. The following table summarizes the DIP
switch settings and their associated features. Note that
after changing any of the DIP switch settings, the AC
power must be turned off and on before the changes
can take effect.
