INFICON I/O1000 I/O module - Manual (Page 10)

10 Description
If the hardware handshake cannot be deactivated, then the RS-232 cable can be
used as follows:
3 - STATUS
Status LED
4 - ANALOG OUT
Analog outputs (for logging leakage rate and backing pressure)
Electrical insulation (max. 60 V DC, 25 V AC against GND)
Connection plug arrangement
The analog outputs can be freely configured.
► For other layouts, see installation manual for mass spectrometer module
LDS3000.
