OMMUNICATION
This switch allows you to define:
♦
The total number of TBOS displays the MAP interrogates
using switches S3-1 to S3-5.
You must count all unused displays until you reach the
TBOS system total size. After you reach that size, the
MAP ignores all displays.
In Fig. 15, the group settings for displays per port total
21 TBOS displays. The MAP ignores port 8 because there
are 19 total displays, but the MAP counts one unused
port 6 display in the total.
If there are no discrete points (switch S3-8 is OFF) the num-
ber of displays is 1-32. If there are discrete points (switch S3-
8 is ON) the number of displays is 0-31. Use 0 if the MAP
communicates only with discrete points.
If you do not use all TBOS displays, you can use the
remaining MAP capacity for discrete points connected
through port 1. Refer to Fig. 15.
♦
The number of TBOS serial ports that operate at 1200 baud
instead of the default 2400 baud using switches
S3-6 and S3-7. Set the number of ports by group.
♦
Whether the data port communicates with serial ports only
(TBOS-INT) or with serial ports and discrete points (DCM-
INT) using switch S3-8.
Refer to Table C for switch settings.

OTE
:
If the MAP reports to an
E-System master through an
E-System Adapter, you can use
up to four MAPs. Because of sys-
tem requirements, you can only
use 28 displays (1,792 points) on
the first or third MAP. The first
four displays are dedicated to
system use. You can use a full 32
displays (2,048 points) on the
second or fourth MAP.
