4. REMOTE CONTROL
The DLS 50 can be remote-controlled via the IEEE 488 (also known as the GPIB bus)
and RS-232 (serial) interface, allowing the integration of the DLS 50 into a larger test
system.
The DLS 50 remote control is designed with several standards in mind:
• The GPIB physical interface follows IEEE 488.1. The functions
implemented are outlined in Section 4.1 "IEEE 488 Interface".
• The Common Commands follow IEEE 488.2.
• The Device Dependent Commands (see Section 4.7) are based upon the
Standard Commands for Programmable Interfaces (SCPI). However, we
had to create some device dependant commands since there was no pre-
defined SCPI command that could apply to the DLS 50.
• The serial port physical interface follows the EIA RS-232 standard.
The IEEE 488 and the serial interfaces are always enabled, and can be used
alternatively. The DLS 50 directs its output to the last interface it received data from.
Both interfaces use the same command set and produce the same results.
Section 4.1 and 4.2 describe the functions specific to one particular interface, the
remainder of section 4 describes the commands that are common to both interfaces.
