Modular products require installation in a suitable PXI/LXI chassis. The module is designed for indoor use only. PREOPERATION CHECKS (UNPACKING) 1. Check the module for transport damage and report any damage immediately to Pickering Interfaces. Do not attempt to install the product if any damage is evident.
For a system comprising more than one chassis, turn ON the last chassis in the system followed by the penultimate, etc, and finally turn ON the external controller or chassis containing the system controller. 9. For Pickering Interfaces modular LXI installation there is no requirement to use any particular power up sequence.

MODULE ARCHITECTURE 40-656A: MULTIPLEXER MODULE The 40-656A Multiplexer Module utilises an array of 38 DPST relays. In the default state all relays are open circuit. Energising a particular relay creates a signal path between the common terminals and the corresponding channel terminals.
SECTION 4 - PROGRAMMING GUIDE pickering PROGRAMMING THE MODULE 40-656A Here are some simple examples of using the drivers with the 40-656A Multiplexer module. Using PILPXI To operate a relay the user could use the simple OpBit command or the WriteSub commands OpBit DWORD sub_unit = 1;...
PCI configuration, highlighting any potential configuration problems. Specific details of all installed Pickering switch cards are included. All the installed Pickering switch cards should be listed in the “Pilpxi information” section - if one or more cards is missing it may be possible to determine the reason by referring to the PCI configuration dump contained in the report, but interpretation of this information is far from straightforward, and the best course is to contact Pickering support: support@pickeringtest.com, if possible...
For PXI modules which are supported in one of Pickering Interfaces’ Modular LXI Chassis (such as the 60-102B and 60-103B) no module software update is required. If the module was introduced after the LXI chassis was manufactured the module may not be recognized, in this case the chassis firmware may need upgrading.
