RS232 connections
Option C is the adaptor cable recommended for use with the
RS232 serial communication interface. The adaptor cable has,
at one end, 6-pin LEMO type connector and, at the other, a 9-
way D type connector. The instrument's serial communication
settings and the data terminal equipment (DTE) settings must
be the same. The recommended initial settings are as follows:
Baud rate - 9600
Data bits - 8
Stop bits - 1
Parity - none
Handshaking - none
Adaptor Cable
Notes
1. The function column for the D type connector uses RS232
terminology with respect to DTE.
2. In the D-type connector DTR and DSR should be connected
together as follows:
9-way pin 4 and 6
25-way pin 20 and 6
3. The instrument's serial communication settings can be
changed using the set-up menu.
