COMMUNICATIONS MODULE
Your AT30 Microprocessor-controlled Battery Charger has provisions for an optional
Communications Module that allows the user to remotely monitor and control the unit
over a serial connection. This option supports
DNP3 Level 2
and
Modbus
protocols
over
RS-232
or
RS-485
half-duplex. Industry-standard
SCADA
(Supervisory Control
And Data Acquisition) systems will be able to control, monitor and log the events of
the battery charger when this option is supplied. The system can also be used with a
modem for telephone communications. All features of the AT30 battery charger’s front
instrument panel are accessible remotely, using the Communications Module.
The AT Series Communications Module option (
EJ5037-xx
) includes the
Communication PC Board (A12), external power supply resistor(s) (R29x), an
Operating Instructions manual, and a field-retrofit instruction sheet (
JD5008-00
). An
unlabeled copy of the Communications Module Operations Manual is available for free
online (
http://www.ATSeries.net/PDFs/JA0102-04.pdf
). A compatible industry-
standard modem and modem cable are also available. Contact your sales representative
