COMMUNICATIONS MODULE
Your AT10.1 Battery Charger has provisions for an optional Communications Module
that allows the user to remotely monitor and control the charger over a serial
connection. This PC Board Assembly (A12) supports DNP3 Level 2 and Modbus
protocols over RS-232 or RS-485 half-duplex. The system can be used with a modem
for telephone communications. All features of the AT10.1’s front instrument panel are
accessible remotely, using this option. SCADA (Supervisory Control And Data
Acquisition) systems will be able to control, monitor and log the events of the battery
charger.
The standard Communications Module kit (EJ5037-XX) includes the Communications
PC Board (A12), an external power supply assembly (A14), a separate AT Series
Communications Module Operations Manual (JA5026-00), and field-retrofit
instructions. The Communications Module Operations Manual, along with a sales
catalog cut sheet, is freely available for download from the web site featured on the
back cover of this manual. A compatible industry-standard modem and modem cable
are also available. Contact your sales representative to place an order for the AT Series
Battery Charger Communication Module. Refer to the table below for ordering
information.
