3.7 Connecting Stabil-Ion Remote Control
This factory installed option permits the following functions to be controlled from a remote
location:
In addition, the following functions are output in the form of relay contact closures which can signal
the status of the instrument to a remote location, or control external devices.
The optically isolated control inputs are on a 26 pin remote input connector. The relay contact
outputs are accessible on the 15 pin remote output connector.
3.7.1 Definition of Input States
“Hi” = open circuit or TTL “1” state (to maximize noise immunity, pull up to +5 volts (pin 21)).
“Low” = closed circuit selection to option common or TTL “0” state.
Maximum current = 2 mA per low input.
