SRS Residual Gas Analyzer
Initialization Commands
ID?
Description : Identification query.
Echo: ID string.
Use to identify the RGA head connected to the host computer.
The RGA returns the ID string (ASCII format):
SRSRGA###VER#.##SN#####<LF><CR>
The three string parameters, in the exact format shown above, correspond to:
1. Model number (=M_MAX): 100 for RGA100, 200 for RGA200 and 300 for
the RGA300.
2. Firmware version ( for example: 0.23).
3. Serial Number of the unit (5 digit format).
The ID command is used for a variety of purposes:
x
Make sure the RGA is powered up and ready to go.
x
Check the quality of the RS232 connection to the host computer.
x
Check the user’’s communication software to make sure it is communicating
properly with the RGA.
x
Check the serial numbers of the RGA heads connected to the computer's
serial ports. The unique serial number attached to each head can be used for
identification purposes avoiding the problems caused by cable swapping in
the RS232 connections under multiplexed operation, or head swapping in the
vacuum system.
Parameters: Only one possible format:
ID?
Error checking:
Only a query format is accepted. Anything else results in a Bad-parameter error.
IN0, IN1, IN2
