Remote I/O Connector
Allowable Cable Length
IMG Board
The IMG board operates Varian IMG-100 and IMG-300 gauges and allows you to set gauge
sensitivity value, and gas correction factor. The UHV range is standard, as is remote I/O
control of emission and 0 to 10 V analog output.

6 pin Firewire type
Grounding the input pin activates that function
The Status Output goes hi during an error.
Note: the analog outputs for CNV1 and CNV2 are also
available at pin 7 of their respective Dsub connectors.

❑ Varian IMG-100, IMG-300
❑ 5.0E-12 Torr to 2 mTorr (IMG-300)
❑ 5.0E-12 Torr to 5 mTorr (IMG-100)
* This represents the ability of the controller to display pressure
values and not the capability of the gauge heads to accurately
measure pressure.
