XTM/2 Operating Manual
3.8 Computer Communications
This instrument supports a number of standard and optional computer
communications protocol formats. RS232 is standard, operating in either
INFICON checksum or non-checksum as well as SECS II formats. The unit may
also be configured to automatically output process data (data logging) upon
reaching FINAL THICKNESS. Pressing the shutter CLOSE switch on the front
panel will also initiate a data dump.
3.8.1 Communications Setup
The XTM/2 has serial communications as a standard feature. Rates from 1200
to 9600 baud are accommodated. Refer to
for
RS232 connector details.
To configure the remote communication interface, hold down the 0 key during
power up. The following set of parameters can then be entered using the digits,
enter, and clear keys.
When this list is complete, the RECEIVE message is flashed and the choice will
be given to either repeat the list or continue with normal operation. Pressing
ENTER will continue with normal operation. Pressing CLEAR will repeat the list.
NOTE: Do not turn the unit off while in the Communications Program Mode,
otherwise the new parameter values will not be saved properly.
