OPERATION

Bleeder Control



The Master unit is used to control the
bleeder settings. The bleeder resistors in all
the slave units are always turned off when
in parallel mode.

Master-Slave Parallel Connection

Master-Slave
Connector

The Analog Control Connector is used for both
serial and parallel connections. The way the
connector is configured determines the
behavior of the master and slave units. For the
complete connector pin assignment, see page
