13 GPIB DAUGHTER BOARD
13.1 Description of the GPIB daughter board
GPIB is a parallel interface that allows a single computer to control a number of instruments
independently. The GPIB interface on the iTC conforms to the standard IEEE-488.1. The GPIB
must be connected using a standard GPIB cable.
The GPIB interface fully complies with IEEE-488.1-1987 as a talker/listener, able to generate
service requests and to respond to serial poll and device clear commands. The interface does
not support parallel polling and has no trigger function. Open-collector drivers are used on the
bus lines, so the instrument does not prevent parallel polling of other devices connected to the
bus.
The complete GPIB conformance of the instrument is specified by the Capability Identification
Codes:
SH1 AH1 T6 L4 SR1 RL0 PP0 DC1 DT0 C0 E1
13.2 Installing a GPIB board
13.2.1 Fitting the board
A GPIB board can only be fitted in the dedicated GPIB expansion slot. Otherwise, the procedure
for fitting a GPIB board is as described in section 5.2.
13.2.2 Basic check of board operation
1 Power up the MercuryiTC. If fitted correctly, the iTC will detect the board and may request
permission to use it.
2 Put the iTC in Local mode by tapping the local/remote toggle button on the iTC Home page.
3 Tap Settings, scroll to and tap the Devices tab.
4 Scroll down the list of devices and find the level meter board. Also, scroll to the right to read
the firmware version.
