tion the RS-485 address (Axxx) must precede every command (e.g., to set the brightness to 3
and output voltage to 30 of a unit with RS-485 address 001, send
A001DISP:CONT 3;A001VOLT 30)

2.7.3 SETUP FOR REMOTE OPERATION VIA GPIB
CAUTION: DO NOT CONNECT THE POSITIVE OUTPUT TO GROUND WHEN IEEE 488 IS
USED. THERE IS A POTENTIAL SHOCK HAZARD AT THE IEEE 488 (GPIB)
PORT WHEN POWER SUPPLIES ARE USED WITH RATED OR COMBINED
VOLTAGE GREATER THAN 400V AND THE POSITIVE OUTPUT OF THE
POWER SUPPLY IS GROUNDED.
Operation via GPIB is possible if the optional GPIB interface is installed. With all power off, con-
nect the load to the KLN 750W using either local or remote sensing. If units are to be connected
in series or parallel, refer to PAR. 2.8. Connect the GPIB connector to the GPIB port (see Figure
2-1 and Table 2-1). Turn power on and refer to PAR. 3.2 for power supply basics and PAR. 3.6
for remote mode programming.
The default GPIB address is 07; to change it refer to PAR 3.3.17. The unit automatically enters
remote mode when a command is accepted.
SCPI programming is described in PAR. 3.7; Appendices A and B provide syntax for SCPI com-
mon and subsystem commands and queries implemented in this unit. All the features described
for Local Mode operation can be accomplished using remote SCPI commands.
2.7.4 SETUP FOR REMOTE OPERATION VIA LAN
Operation via LAN is possible if the optional LAN interface is installed.
Connect a computer to the LAN connector at the rear panel using a standard RJ 45 Ethernet
cable (not supplied). The LAN interface uses LAN Port 8003 for Telnet connections.
See PAR. 3.6.3 to operate the unit via the LAN interface.
2.8 MULTIPLE UNIT CONFIGURATIONS
Parallel and series configurations of identical KLN 750W units increase the rated current and
voltage range of the power supply. Up to five units (including the master) can be connected in
