UPLC-II™ System Manual
5.2.5 Other Connections
All the other connections to the UPLC-II™ are for
alarm and information purposes. These inputs and
outputs are listed here for reference purposes.
Depending on the options ordered, these outputs
may or may not be present. These will be listed
from left to right looking at the rear of the chassis.
5.2.5.1 Ethernet Connectors
• Ethernet Ports: (TX1, RX1 & TX2, RX2)
Depending on options ordered, these con-
nections may be electrical RJ-45 or fiber ST
connectors.
5.2.5.2 Protocols Connector
Please refer to Chapter 7, “Communication
Protocols” for more details.
• 9-Pin D shell Connector (J4): This connector
is for a permanent connection, which pro-
vides RS232 or RS485 access to the unit for
the DNP3 communication protocol.
RS-232: (see figure below)
RS-485: pins 2 & 8 (TX +/–)
pins 3 & 7 (RX +/–)
• The rear Ethernet ports, listed above, can
also be used for DNP3 and/or IEC 61850
communications. The front Ethernet port is
not available for protocol communications.
Standard RS-232 Extension Cable
5.2.5.3 IRIG-B Input
• BNC Connectors (J13 & J14): These con-
nectors are for the IRIG-B input. J13 is the
input for a modulated IRIG-B signal and J14
is the input for a TTL Unmodulated IRIG-B
signal. Only one of these inputs should be
used, not both at the same time.
NOTE: No setup is required for IRIG-B. Simply
connect to the correct coax connector to match your
source.
5.2.5.4 CLI (Carrier Level Indicator) Output
• TB7-3(+) & TB7-4(–): These two terminals
provide an output that tracks the RX fade
margin level. It can be connected to an exter-
nal voltage transducer which can then con-
nect to SCADA to remotely read the receiv-
er’s margin, if desired. It requires an external
source of 10–300 Vdc be applied in series
with it. (Calibration of this output can be
done through the front key pad or the web
browser calibration page.)
5.2.5.5 Power Supply Outputs
• TB1-3(+) & TB1-4(-): Main power supply
Auxiliary output for feeding 20 mA or
200 mA to an electromechanical auxiliary
blocking relay such as a KA-4 or SCA carri-
er auxiliary relay.
• TB1-5 & TB1-6: Main power supply failure
alarm dry contact.
• TB2-3(+) & TB2-4(-): Redundant power
supply Auxiliary output for feeding 20 mA
or 200 mA to an electromechanical auxiliary
blocking relay such as a KA-4 or SCA carri-
er auxiliary relay.
• TB2-5 & TB2-6: Redundant power supply
failure alarm dry contact.
5.3 Hardware Jumper Settings
Some of the settings on the UPLC-II™ require the
use of a hardware jumper. These are settings, which
involve selections being made on circuits that are in
surge sensitive areas. The jumpers are dual jumpers
because one side is the actual jumper setting and the
other is the sensing side. The microprocessor can
then look at the sensing side and report the physical
jumper setting on the web pages and in the settings
download file, without having to open the unit to
view them. Although it looks like two separate
jumpers for each selection, it is really a ganged
jumper.
