SECTION 7 - MAINTENANCE INFORMATION
SOFTWARE UPDATE
For PCI modules operating in a PCI system, no module software updates are required. For the latest version of
the driver please refer to our web site
www.pickeringtest.com
where links to our Software Download page will
provide the latest version of the driver software for the various programming environments encountered.
RELAY LOOK-UP TABLES
See Section 4 for a cross reference between the switching channels of the Reed Relay Module and the physical
relays on the PCB.
The tables can be used in the fault finding process and should be used in conjunction with the PCB layout diagram
below to identify the position of faulty relays.
