NOTE: The following procedure assumes that both individual units are properly calibrated. If not, refer
to the associated technical manuals to calibrate the individual units prior to connecting them
as a parallel pair. Perform all calibration steps for both master and slave unit.
1. Before powering up the parallel combination, connect the Power Output, Bitbus, and Master/
Slave Control cables (supplied) to the master and slave units in parallel star type configuration
(load connected to the master output) as shown in Figure 1 for local sensing or Figure 2 for
remote sensing. Always remove link between COM and COM S terminals for the slave. For a
master configured for remote sensing, remove both links between OUT and OUT S and between
COM and COM S terminals.
CAUTION:The connectors of the Master/slave Control cable are marked Master and Slave.
Make sure these are installed properly. Installing the cable backwards (cable con-
nector marked MASTER installed in a slave, cable connector marked SLAVE
installed in a master) can cause irreparable damage.
NOTE: To power down the combination, first press the STANDBY key on the master to disable the
output, then turn off the slave followed by the master.
2. To configure the unit to be designated as a slave proceed as follows:
a. Turn on power only to the unit to be designated as a slave.
b. From the main screen (power on default), press % to enter the Settings Menu.
c. From the Settings menu, gain access to the Protected Settings menu by first entering the
password. Scroll through the password characters using U or ADJUST control and T or R

. (If unsuccessful, use T or R to highlight the incorrect charac-
ter and U or ADJUST control to fix it, or press CLEAR to start over.)
d. Press $ to enter the Protected Settings Menu.
e. From the Protected Settings menu, highlight
Unit Type
(use ADJUST control or the Y or
U keys) and press ! to modify. Highlight

and press ! apply the change.
f. From the Protected Settings menu, under
Unit Type

tings upon power-up. The unit goes to REMOTE mode, the status message reads
MASTER
Module not found
, the Fault indicator is lit, and the unit continues to beep once a minute
until the master is found. The only function key displayed is ! - LOCAL.
CAUTION: The unit has now been properly configured as a slave to be controlled only by the
master. Do not use the slave keypad, RS 232 port or GPIB port to try to control the
slave.
