Ethernet ECC21 communication card
The ECC21 is an optional ethernet communication card. It may be installed in one
of the two slots in the circuit monitor intended for optional cards. It has two main
functions:
■ Equip the circuit monitor with a fast ethernet connection over a 10/100 Mbits/s
copper link or a 100 Mbits/s Fibre optic link
■ Serve as an ethernet gateway for devices daisy chained to its RS485 Modbus
port. The ECC21 card also includes a server for six HTML pages that may be
consulted by a standard web browser. The pages may be customised and
display information from the host circuit monitor and/or devices connected to
its Modbus port.

CVM current/voltage module
This is the CM4000 acquisition module for currents and voltages. It is supplied
already installed on the CM4000. If the circuit monitor must be recalibrated, this is
the only module requiring recalibration. It may be installed and removed in the
field. This module may also be replaced in the field by a CVMT module (see the
next paragraph) to transform a CM4000 into a CM4000T.
Description Part number
Current/voltage module for CM4000 CVM
CVMT current/voltage module
This is the CM4000T acquisition module for currents and voltages, i.e. it is suitable
for the detection of transient phenomena with a 5 MHz voltage sampling rate.
Similar to the CVM, it may be installed and removed in the field. It is supplied
already installed on the CM4000T.
