use RS-232C cable with an outer shield. To
protect against applied transients, you should
ground the shield to the base terminal chassis
ground.
The equipment (e.g., modem, event recorder,
microcomputer) you attach to the module
should be no more than 50 feet away, per RS-
232 standards.
16.3.2 Software Settings
There are no configurable settings for the Low
Speed Data (232) Module, except for the DS0
timeslot assignments. The 232 is a transparent
module (i.e., it does not process the data passing
through it).
16.4 Specifications
The Low Speed Data (232) Module’s technical
specifications are shown in Table 16-2.
16.4.1 Status Indicators
This module has five status indicators, as shown
in Figure 16-3. The red/green status LED is green
if the module is functional and red if the module is
non-functional. The green “TX” LED, when lit for
either channel, indicates that the module is trans-
mitting data on that channel. The green “RX”
LED, when lit for either channel, indicates that the
module is receiving data on that channel.
