• Port 5025 - SCPI Raw. This port supports up to two connections. The SCPI-Raw port
provides faster access than the VXI-11 port (1024) as it has little overhead. This port is
accessed using the VISA resource string, e.g.:
TCIPO::192.168.1.100::5025:SOCKET
• Port 5044 - Trigger Port (UDP LXI and TCP/IP).
2.4 DIGITAL CONTROL VIA GPIB
KLR Power Supplies may be programmed over the IEEE 488 standard communication bus
(General Purpose Interface Bus, GPIB) control bus using SCPI (Standard Commands for Pro-
grammable Instruments). Use the SYST:COMM:GPIB:ADDR? query to read the current GPIB
address. Use the SYST:COMM:GPIB:ADDR command to change it. Refer to Section 6, PRO-
GRAMMING THE KLR USING SCPI COMMANDS, and Section 7, IEEE 488.2 (GPIB) INTER-
FACE. for additional details on using the GPIB interface.
2.5 DIGITAL CONTROL VIA RS 232 [STANDARD MODELS ONLY]
KLR standard models may be programmed over the RS 232 control bus using SCPI (Standard
Commands for Programmable Instruments) (see Section 6). All power supply functions avail-
able from the front panel can be programmed via remote commands, as well as some that are
not available from the front panel: Save/Recall (see PAR. 1.2.5) and List (see PAR. 1.2.6). Refer
to Section 8, RS 232C INTERFACE [STANDARD MODELS ONLY] for additional details on
using the RS 232 interface.
The KLR Power Supply may be operated via an RS232-C terminal, or from a PC using a termi-
nal emulation program. Refer to KLR User Manual for RS 232 connections.
All RS 232 parameters may be changed using SCPI commands (see Appendix B) as follows:
• To enable RS 232, refer to PAR’s B.86 and B.87
• For baud rate, refer to PAR’s B.82 and B.83
• For prompt, refer to PAR’s B.90 and B.91;
• For echo, refer to PAR’s B.84 and B.85;
• For XON/XOFF, refer to PAR’s B.88 and B.89.
The default settings are as follows:
• Baud rate: 38400
• Parity:
None
• Data Bits 8
• Stop Bits 1
• Echo OFF
• XON ON (enabled)
