Appendix B-6
GSIOC Control Appendix B
Buffered Q Enter Pressure Value
Syntax: “QBxx.x” in bars, “QPx.xx” in MPa, or “QKxx.x” in kpsi.
Parameter: if xxx is omitted, the pressure value is read from the
manometric module and the pressure unit is selected for the immediate Q
command.
Command example: “QP1.23” for 1.23 MPa.
Comment: this command does not affect the pressure unit on the display.
Immediate Q Read Pressure Value
Response format: as above, in the pressure unit used by the last Q
buffered command. The default selection is in bars.
Response example: “B321” for 321 bars.
Comment: if no manometric module present, “N” is returned.
Buffered W Write Display
Syntax: “WO = x..xx” for upper line, “W1 = x..xx” for lower line.
Parameter: x..xx is a 24-character long alphanumeric string. All 7-bit ASCII
characters are valid. Note that characters shown on the Japanese-made
display unit may differ from characters sent by a micro-computer (if used
as a master controller).
Immediate W Read Display
Response format: “W0 =” (upper line) or “W1 =” (lower line) plus 24-
character alphanumeric string.
Response example: “W0 = Flow rate 1.000 mL/min”.
Comment: the first line to be returned is the last entered by the buffered W
write command. If the write command has not been used, the upper line of
display is read at the first occurence of the read command. The other line
is read at the second one. And so on.
Immediate w Read Display Buffers
Response format: as above.
Comment: reading mechanism same as above. The response is the image
of the related display line from the buffer. This is also the message which
will be restored to the display after a partial (W0/W1) or total (W) command.
GSIOC Commands
Identification Number
The Model 305 identification number is factory set
to 1. In a multi-pump configuration, it is necessary
to change the addresses of the slave pumps
according to the opposite table.
To change the GSIOC ID number, turn the power
ON. Press <Menu>, <I/O>, then <Prev>. The
display comes “GSIOC Unit ID: 1”. Key in the
desired number (from 2 to 4) and confirm by
hitting <Enter>, then <Quit>.
If a Model 302 or 303 pump is used as a slave
pump, its ID number must also be changed by
setting DIP switches on the Thumbwheel PC
Board. See the related User’s Guide on how to set
ID number.
