8.8 Remote control via an RS-232 connection
The 876 Dosimat plus can be remote controlled via an RS-232 connection.
For this, a 6.2148.030 RS-232/USB Box is necessary. Connect the
RS-232/USB Box to the USB interface of the instrument.
The RS-232/USB Box has two connectors for RS-232 instruments. The
RS-232 remote control functions only through the connector RS-232/2.
The connector RS-232/1 is designed for connection with a balance. Con-
nect the RS-232/2 connector of the RS-232/USB Box to a serial interface
(COM interface marked with the symbol IOIOI) of a PC. Use a
6.2134.040 connection cable.
