AT SERIES COMMUNICATIONS MODULE

DNP3 LEVEL 2 / MODBUS COMMUNICATIONS

FOR THE AT10.1 AND AT30 SERIES BATTERY CHARGERS

•

The AT Communications Module allows the user to remotely monitor and control
the AT Series Battery Charger over a serial connection.

•

Supports DNP3 Level 2 and Modbus protocols over RS-232 or RS-485 half-
duplex.

•

The option can be used with a modem for telephone communications.

•

All features of the AT Series front instrument panel are accessible remotely.

•

SCADA (Supervisory Control And Data Acquisition) systems will be able to
control, monitor and log the events of the battery charger.

The AT Series Communications Module Option (

EJ5037-xx

) includes the AT Series

Communications PC Board (A12), external power supply resistor(s) (R29), an Operating
Instructions manual (

JA5026-00

), and a field-retrofit instruction sheet (

JD5008-00

). A

compatible industry-standard modem and modem cable are also available. Refer to the items
listed below for part information and check off which items were supplied.
