
Station ID (CWID)
Enter the Station ID (CWID) or FCC Call Sign for the system. It is sent out as Morse Code at predetermined intervals.
Station ID is a combination of letters (upper-case) and numbers (0 - 9) up to 9 characters in length.

CWID Interval
CWID Interval is used to set the interval of time the unit will transmit the Station ID (CWID) or FCC Call Sign. The
range is 1 to 255 minutes in 1 minute intervals, with 0 being disabled. To enable the transmissions of the Station ID
(CWID) or FCC Call Sign, a non-zero value must be set for the CWID Interval. Only one unit in a system should be
programmed to transmit the Station ID (CWID), typically the Master.

Extended Preamble
This field extends transmitted synchronization time when the unit is used in a network with repeaters. The default
is 5 mS and the range is 0 to 100 mS in 5 mS intervals. Add 10 mS for each Repeater an Integra-TR communicates
through in a network (dependent on user’s protocol). Note: Units supplied or updated prior to November of 2001
use a default value of 0 mS for Extended Preamble. Extensive testing has shown 5 mS to be the most robust
setting. If timing is critical in your application, this value can be set back to 0 mS.

Suspend Period
Set the length of time the Integra-TR goes to cycled lower power mode. The range for Suspend Period is from 50 to
12,000 mS in 50 mS intervals. Setting this range to a value of 0 disables Suspend Period.

Activity Timeout
Activity Timeout is used to set the minimum length of time the unit will remain awake in the presence of a carrier range is 1 to 255 seconds in 1 second intervals. This field is active only if Suspend Period is enabled. A non-zero
value must be set to enable Suspend Period. The same Activity Timeout and Suspend Period values must be set for
both Master and Remote units. See
Figure 17 for a Suspend Mode Timing graphic.
