REMOTE CONTROL RS-232
Description:
The oscilloscope is equipped with an RS-232 Interface as standard. This can be
used for remote control or for setting the readout using an external controller or PC.
The language used is called CPL (Compact Programming Language) and is
described in Chapter 6. CPL is a small set of very powerful commands for full
remote control of all oscilloscope functions. The male 9-pin connector and its
connections are shown in the figure below.
For correct functioning Communication parameters must be adjusted. This is
done in the menu UTILITY RS-232 SETUP. This menu is reached via the key
sequence ’UTILITY >> RS-232 SETUP >> ......’. Possible Selections are:
- Baud rate. To be selected with the TRACK control.
- Number of DATAbits and PARITY. Combinations are
dataBITS:77888
PARITY: Odd Even Odd Even No
There is always one stopbit.
- Hardware handshake is selected with ’3-wire/7-wire’. In the 7 wire position the
hardware handshake signals DSR/DTR and CTS are active.
- Software handshake is selected with ’XON-XOFF on off’.
Operation of the front panel key STATUS LOCAL
passes the control of the oscilloscope from the
interface (remote) to the front panel keys (local).
