USER’S GUIDE

Battery Management System

Local access to the control console. You can use a local computer, a

computer that connects to the Battery Management System through the

serial port, to access the control console.

1. Select a serial port at the local computer and disable any service which

uses that port.

2. Connect the serial cable (940-0103) that came with the Battery

Management System to the RS-232/485 port on the Battery

Management Unit and a serial port on your local computer.

3. Run a terminal program (such as HyperTerminal) and configure the

selected port for 9600 bps or 19200 (depending on the speed

configured for Modbus), 8 data bits, no parity, 1 stop bit, and no flow

control. Save the changes.

4. Press

ENTER twice to display the User Name prompt.

5. Enter your user name and password (apc by default).

Modbus and the control console share a common serial port.

You can use either one or the other to access the Battery

Management System. If you reconfigure the DIP switches to

switch from Modbus to the control console, you must restart

the computer for the changed to take effect.
