Unit ID
The unit ID identifies the liquid handler to software packages that can issue GSIOC commands to the liquid handler.
The unit ID is set to 20. There is no need to change this number unless it has been assigned to another Gilson instrument that is
also connected along the GSIOC.
To change the unit ID:
1 Gently insert a small flat-blade screwdriver into the unit ID selector on the rear panel and turn it. See rear panel on page 2-15
.
2 Align the white dot with one of the indicated numbers. The unit ID is 20 plus the selected number.
GSIOC Communication
The liquid handler is shipped with one of the following types of communication, Ethernet, RS-232, or GSIOC. The following
instructions apply to GSIOC communication. For information on Ethernet communication, refer to page 2-16
