GSIOC Commands
R I Returns the current valve position (0–8).
For a 2-position valve, the first position is 0 and the second
position is 1.
T I Returns ‘xxPs-yyPt’, xx is the number of positions and yy is
the number of ports in the valve.
U B Unlocks the keypad.
V I Identifies the manufacturer and model of the installed
valve. Returns ‘an...n’ where:
a - first letter of the manufacturer name (R for Rheodyne
or H for Hamilton)
n...n - model number, for example, 7010 or 86905
W I Reads the display. Returns ‘W0=x...x’ for the upper line or
‘W1=x...x’ for the lower line, where x...x is the character string
shown on the display.
The immediate W command returns the line specified in the
last-sent buffered Wn=x...x command. If a buffered
Wn=x...x command has not been sent, the immediate W
command returns the upper line. If the immediate command
is sent again, it returns the lower line.
Wn=x..x B Disconnects the upper or lower display line from the
VALVEMATE software and prints the character string
designated by “x...x”.
The parameter n identifies the display line to disconnect:
0 - Disconnects upper display line
1 - Disconnects lower display line
To reconnect the display, use the buffered Wn command.
Wn B Reconnects both or one of the display lines to the
VALVEMATE software depending on the value assigned
to n:
0 - Reconnects upper display line
1 - Reconnects lower display line
If you omit the parameter n, both lines are reconnected,
and the VALVEMATE software will display prompts and
data.
