J5 – Gauge Connector
Mini-TASK AG81 is equipped with new generation
gauge reading card able to drive/read a Varian
"EyeSys Mini-IMG" gauge.
The EyeSys Mini-IMG is a vacuum measurement
instrument based on the inverted magnetron ion
gauge design (see orderable parts table).
The gauge pressure operation range goes from
-3
-3
6.6x10
mbar [5x10
-9
[5x10
Torr] and its operation temperature range
goes from 0°C to 50°C [32°-122°F].
Pressure data is available on three independent
reading channels:
1.
On-board display (data expressed in mbar,
Torr or Pa) – (see Pressure Display Module
picture)
2.
Serial communication line (Win 224)
3.
Analogical output.
Pressure gauge can be connected/disconnected
from the Mini-TASK AG81 during normal opera-
tion.

NOTE
The Mini-IMG gauge is intended for high vacuum
use, so with pressure above 50 mTorr the signal is
misinterpreted and a "false" pressure is displayed.
Use a transition gauge to understand if the reading
is really under 50 mTorr or not.

J1 – IN-OUT
This connector carries all the input and output sig-
nals to remote control the Mini-TASK AG81.
It is a 15-pins D type connector; the available sig-
nals are detailed in the table, the following para-
graphs describe the signal characteristics and use.
