2.6 RS-232-C SERIAL INTERFACE

Your oscilloscope is equipped with an RS-232-C interface as standard. The interface can be used in a system for serial communication. The protocol used is CPL (Compact Programming Language). CPL is a small set of very powerful commands that can be used for full remote control. Detailed information about this interface and the CPL protocol is given in Chapter 6 in this manual. For setup information, refer to the REMOTE CONTROL RS-232 function in Chapter 5 ’Function Reference’.

2.7 RACK MOUNTING

The rackmount kit (PM 8960/04) allows you to install the oscilloscope in a standard 19 inch rack.

It is not necessary to open the oscilloscope itself to mount the rackmount kit. Installation can be done easily by the user.

2.8 VERSIONS

The model number of your oscilloscope (e.g. PM33...) is indicated on the text strip above the CRT. This model number is also represented by the digits 6, 7, 8 and 9 of the 12- digit code on the type plate on the rear panel. The ’A’ or ’B’ series is indicated by a 1 or 2 on the 5th digit.

The instrument’s serial number is also given on the type plate. This number consists of a six digit code preceeded by the characters ’DM’.

The instrument version can also be displayed on the CRT after having pressed menu key UTILITY and then softkey MAINTENANCE.
