5.7 Alarm Connections
NOTE: To aid the user with installation, frequent reference is made to drawings located at the rear of this manual.
Custom configurations may be detailed within the Argus power system documentation package.
For terminal block connections, the recommended wire sizes are 0.14 to 1.50mm 2 (#26 to #16 AWG) for the
temperature range of 0 to 50 deg. C (as per UL/CSA).
CAUTION: to reduce risk of fire, use only 0.14mm
2
(#26 AWG) or larger wire.
Route via wire-ways and use existing cable clamps to secure to existing (factory) wire harness along with
customer run signal wires. Ensure signal wires are routed along hinge point of front door so door opening and
closing won’t require excess wire slack.
Terminal block connections for the internal alarm card or CXC I/O should be routed along the left side of the
DCP03 (looking at unit from front). Refer to the customer connections (“–08”) drawing at the rear of this manual
for details on terminal block assignments.
5.8 CAN Serial Ports
Two CAN Serial ports (modular jacks with offset latches), for communications with Argus’ Cordex rectifiers and
other CAN-enabled equipment (nodes) on the same system, are located on the side of the rectifier shelf.
Daisy-chain from node to node (CAN OUT of one shelf to CAN IN of another) as necessary and ensure that only
the last shelf is terminated as follows:
5.8.1 CAN Termination
A CAN termination jumper is located beside the rightmost rectifier connector on the front of the shelf backplane.
See the customer connections drawing for your shelf.
The CAN bus may be OPEN to the next node in the system or TERMINATED on the final node on the CAN bus.
5.9 Network Connection and Remote Communications via CXC
The Cordex system can be set up, monitored and tested via Ethernet 10/100 Base-T serial data connection. The
communication protocol supports a web interface.
NOTE: Pinouts are shown in customer connections drawing.
Some standard scenarios are described below:
5.9.1 Ethernet Port for Network Connection (Standard Network Cable)
The Ethernet port is designed for CXC connection to a user supplied network (TCP/IP secured by user) via a front
panel RJ-45 jack.
Connect using a standard network cable.
5.9.2 Ethernet Port for Local Connection (Crossover Cable)
Local access (e.g. laptop computer) is also possible from the Ethernet port connection.
Connect using a standard network crossover cable.
