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.
