5.3.6

Analogue Output, Chart Recorder Output and External Control (Control)

The connector marked Control
the connections for the analogue outputs for the signals of the individual measurement
channels, the chart recorder output (programmable analogue output ) as well as the inputs
for externally controlling the IONIVAC sensors and PENNINGVAC sensors PTR81N,
PTR225, PTR225N, PTR225S, PTR225SN, PTR237 and PTR237N.
Connecting:
 Connect the peripheral components using a shielded connecting cable to the connector
marked Control on the rear of the GRAPHIX controller.

Interfaces RS232/RS485 (RS232/RS485)

The connector marked RS232/RS485
allows you to operate the instrument by means of a computer or a terminal.
Connecting:
 Connect the serial interface of the computer using a shielded connecting cable to the
connector marked RS232/RS485 on the rear of the GRAPHIX controller.
WARNING:
When using the RS232 interface, use a serial extension cable equipped with
a 9-way plug and a 9-way socket. The cable must be of the straight through
type.
To utilise the RS485 interface, a special cable will be required.
