2. Using a thin tool (e.g., a paper clip), press the FUNCTION switch once, then rotate either the
CURRENT or VOLTAGE control until the display reads BAUD; the active baud rate 1000 x
the value visible in the DC AMPERES display (e.g., 38400 is displayed as 38.4). To change
the baud rate, proceed to step 3.
3. Tap the DC OUTPUT switch. The baud rate visible in the DC AMPERES display begins
blinking.
4. Rotate the CURRENT control to change the baud rate, then tap the DC OUTPUT switch to
accept the displayed baud rate. The display briefly reads DONE, then returns to BAUD.
5. Rotate the VOLTAGE control until display reads EXIT, then tap the DC OUTPUT switch to
exit
3.2.14 SETTING UP MASTER/SLAVE CONFIGURATIONS [STANDARD MODELS ONLY]
Both units of a master/slave pair must be identical models. After connecting the RS 232 ports
(see PAR. 2.7.8), proceed as follows to configure the individual units. First configure the slave
(see PAR 3.2.14.1), then the master (see PAR 3.2.14.2). Ensure adequate source power is
available to support the requirements of both power supplies. Output wiring must be in accor-
dance with PAR. 2.7.6 for series output connection or PAR. 2.7.7 for parallel output connection
as applicable; parallel pairs must include load sharing connection per PAR. 2.7.7.1.
3.2.14.1 CONFIGURE POWER SUPPLY AS SLAVE [STANDARD MODELS ONLY]
1. Turn power on. If the unit comes up in setpoint mode (see PAR. 3.2.7), tap either the CUR-
RENT or VOLTAGE control to take the unit out of setpoint mode (status display goes from
SET to blank).
2. Using a thin tool (e.g., a paper clip), press the FUNCTION switch once, then rotate either the
CURRENT or VOLTAGE control until the display reads M/S.
3. Tap the DC OUTPUT switch.
• The status display reads either SERI (series) or PARA (parallel).
• The DC VOLTS display shows the number assigned to the unit (1 = master, 2 or above =
slave).
• The DC AMPERES display shows the maximum number of units in the configuration.
• The factory default is standalone operation (DC VOLTS and DC AMPERES show 1).
4. To change the configuration tap the DC OUTPUT switch once. The DC VOLTS and DC
AMPERES start blinking.
• Specify either SERI (series configuration for higher voltage) or PARA (parallel configura-
tion for higher current) using either the VOLTAGE or CURRENT control by holding in
and rotating the control. Both connected units must be set the same, either SERI or
PARA.
• Specify the total number of units in the configuration to 2 by rotating the CURRENT con-
trol.
• Specify the unit number to be assigned (2 = slave) by rotating the VOLTAGE control.
