Recommended
modem
Honeywell recommends the following modem for the TAC access
communications link.
U.S. Robotics Sportster 9600
This is a commercially available device and is not supplied by
Honeywell. The configuration switches and registers for this modem are
given later in this section.
Other modems that are fully compatible with the U. S. Robotics Sportster
9600 and its configuration may work.
The proper functionality of the communications link to TAC must be
verified at the time of A
X
M hardware installation. Failing to do so can
drastically effect the availability/efficiency of TAC support when it is
needed.
