Jumper Settings
There are six jumpers on the NIS module that set the commu-
nication rate of the receiver analog circuit (refer to Figure
for jumper locations). All six jumpers must be set in the same
position. Jumper setting instructions are silk screened on the
upper left corner of the NIS circuit board. The jumper setting
must match the communication rate set by poles seven and
eight of dipswitch SW3. Figure
shows which pins to jumper
for various loop modes. This figure shows placement of the
pins when looking at the top of the NIS circuit board with the
faceplate on the left.
Power System Status
The communication system provides a means to monitor the
status of the power system of each node. This status informa-
tion can be displayed on the operator console. Electronics
within the power entry panel monitor the power system status.
A single status output is made available to the communication
system. To use this feature, wire the status output to the ter-
minal block on the termination device (NTCL01 or NICL01)
labeled PSS1 or PSS2. Two sets of terminals are available on
each termination device for interconnecting the power system
status output.
This power system status signal is fed through the termination
device cable to the P3 connector on the NIS module. The power
system status input is a TTL-compatible signal. A high voltage
level on power system status indicates good status. A low volt-
age level indicates bad status. When no connection is made to
either of the power system status inputs, a pull-up resistor on
the NIS module causes a high level signal on the power system
status input, thereby reporting good status.
