5.9 Rectifier Connections
5.9.1 CAN Serial Port
A single CAN serial port, for communications with Argus’ Cordex model rectifiers and other CAN-enabled
equipment (nodes) on the same system, is located in between the Ethernet port and RS-485 port options.
Daisy-chain from node to node (CAN OUT of one node to CAN IN of another) as necessary and ensure that only
the last node is terminated.
5.10 Network Connection and Remote Communications
The Cordex system can be set up, monitored and tested via Ethernet 10/100 Base-T or with a RS-232 serial data
connection, or over a phone line using a modem.
NOTE: Pinouts are shown in the customer connections drawing.
The communication protocol supports a web interface. The remote screen display is an enhanced version of the
CXC’s front panel display.
Some standard scenarios are described below:
5.10.1 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 to the Cordex controller using a standard network cable.
On the jack of the CXCP and CXCR only are two LEDs used to provide indication of status. The green LED
illuminates when disconnected and flashes when there is activity on the line. The amber or yellow LED is off when
disconnected and illuminates when a successful (data) connection is present.
5.10.2 Ethernet Port for Local Connection (Crossover Cable)
Local access (e.g. laptop computer) is also possible from the Ethernet port connection using a standard network
crossover cable.
5.10.3 RS-232 Serial (Craft) Port for Local Connection (Null Modem Cable)
Local access to the CXC is possible through the front panel RS-232 serial port using a null modem cable. See
Figure 8 below:

5.10.4 Communication Expansion Board (Modem Straight Through Cable)
The CXC may be equipped with a communication expansion board, which includes a rear RS-232 serial port to
allow the use of an external modem. Connect the modem to the Cordex controller with a straight through cable.
