NGC3 Pressure Gauge Controller Interface Manual Issue 2.0
14.1.
Introduction
The serial interface is RS232-compatible and only one instrument may be connected to a computer serial port.
At switch-on, the NGC3 is reset to local operation mode with the Ion Gauge switched off.
The NGC3 does not check the viability or consistency of commands issued by a remote computer.
14.2.
Interface protocol
1200, 2400, 4800 or 9600 (default) baud, 8 data bits, 1 stop bit, no parity, no handshaking.
14.3.
Local/remote control
An NGC3 starts operation in local control, i.e. using the front panel. In local mode the NGC3 responds only to commands
without parameters (<poll>, <control>, <status> and <reset error>). The <control> command puts the NGC3 into remote
mode, and all the other commands can then be used. The front panel can still be used to change the display but not to
control gauges or change set-points. When a host takes control of the NGC3 emission is stopped, and any current Setup
operation is cancelled. When the host returns the NGC3 to local control, emission is again stopped. The host must
terminate any running bake cycle before returning the NGC3 to local control.
If any relay is permanently Energised or De-energised while in remote control the setpoint for that relay is changed to the
limit so the status of the relay is no longer affected by pressure, either in remote control or on return to local control.
