2.3.4 Reset
A reset button is located on the front panel for restarting the controller’s microprocessor.
NOTE: Refer also to the software manual – always select the Reset menu item before pressing the reset button.
2.3.5 Modem Port
The Modem port is designed for CXCM1 connection to Alpha Technologies Cordex DC Modem #018-585-
20.
CAUTION: Do not connect anything other than the Alpha modem and Alpha-supplied DB-9 cable to
the D-sub port on the front of the CXCM1.
2.3.6 Ethernet Port
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 and a standard network cable.
Local access (e.g. laptop computer) is also possible from the Ethernet port connection using a standard
network crossover cable.
2.3.7 Analog Input Channels
The controller is provided with analog input channels for voltage, current, and temperature.
Voltage Inputs
Two voltage input channels, V1 and V2, provide monitoring of discharge and charge voltage. The CXC
software is pre-configured to monitor V1 for load voltage and V2 for battery voltage. V2 (wired internally) is
used as the system reference for rectifier float voltage, low voltage disconnect (LVD), system high voltage
alarm, and system low voltage alarm.
Current Inputs
The CXC software is pre-configured to monitor I1 for load current wired internally to the system current
shunt.
Temperature Inputs
Two temperature input channels, T1 and T2, provide monitoring of battery temperature and temperature
compensation (temp comp) or room/ambient temperature. A voltage is supplied to these terminals to power
the temperature sensors.
2.3.8 Digital Input Channels
The CXCM1 can accommodate up to two (2) channels and can monitor digital alarm/control signals from
rectifiers, converters and many other types of equipment. See Section 5.9.2.
2.3.9 Alarm and Control Output Relays
The CXCM1 contains four (4) Form C digital alarm output relays to extend alarms and control external
apparatus. Each internally generated alarm or control signal may be mapped to any one of the relays, or,
several signals may be mapped to just one relay or none at all. See Section 5.9.3.
2.3.10 Network Connection and Remote Communications
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. All alarming and control of Cordex
rectifiers is accomplished with a CXC via a CAN bus.
A step-by-step connection wizard – provided to establish remote communications with your CXC – is
available via the Alpha website ( http://www.alpha.ca/downloads ).
