Appendix B. Serial Commands

Response to serial command inquiries approximately 10 ms, response time defined as time
between receipt of last query character to transmission of first response character. Serial
queries more frequent than 10 per second will compromise system responsiveness.

Command Syntax and Definitions

The command format is:
# {XGS-600 address} {command number} {optional data} {carriage return}
The response format is:
> {optional data} {carriage return}
The following characters are used in Table B-1:
Command Description
#
aa RS485 Address
Command
01
Number
c Sensor Code
User Labels
n
Note: Alternatively, "cn" can be used to designate a short code instead of User Label, backward
compatible to Multi-Gauge/SenTorr protocol; see separate instructions below (Table B-1 on page B-2)
h Hex Digit
XGS-600 Gauge Controller
All commands to the XGS-600 must begin with the character "#".
=00 for RS232 (system default). Max allowable: 20hex
Each command is identified by a unique command number, 2
hex digits, 01-FF.
=U, signifies User Label is to follow.
As found on Sensor Setup screen.
Examples:
#00B0UION4UGATE3.2E-03 sets AUTO-ON for ion gauge
"ION4" using CNV gauge "GATE".
#0030UGATE1 turns on emissions of sensor User Label Gate1.
#0055UTOP26.00 sets sensitivity for ion gauge with User Label
Top.
Note: If User Label is not defined by user, default User Label is
Sensor ID.
Used to identify setpoint number or to list status of 8 bits.
