Chapter 4 Communication Interface programming operation

4-1. Introduction

The rear panel Communication Interface programming of 34000A Series mainframe is
designed to connect PC or NOTEBOOK PC with remote control interface, the NOTEBOOK
PC acts as a Communication Interface programming of 34000A Series Electronic Load.
This feature can be used as an automatic load/cross load regulation and centering voltage
testing for a switching power supply or a rechargeable battery charge/discharge characteristic
testing. The function capability of rear panel communication Interface programming not only
can set the load level and load status, but also can read back the load voltage and load
current.
NOTE: When use USB/LAN interface controls the 34000A Series, the 34000A Series will
convert the USB/LAN interface to RS232 interface.

4-2. The summary of RS232 Interface and command

The following RS232 commands are same as GPIB commands. The RS232 protocol in
34000A Series mainframe is listing below:
Baud-rate
Parity
Data bit
Stop bit
Handshaking ：Hardware (RTS/CTS).
The RS232 Interface connector of 34000A Series rear panel, RS232 is shown in Fig4-1.
