Page 17: Installation
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. -
Page 18: Hardware Installation
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. -

Page 22: Module Architecture 40-792
MODULE ARCHITECTURE 40-792 The 40-792 utilises an array of thirty four 2 Form C changeover relays. In the default state the daisy chain is routed through all tributaries and the multiplexers are inactive. Energising a particular relay creates a signal path between its C and A terminals the effects of which vary depending on the relays function. -

Page 29: Maintenance Information
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. - Page 30 RL21 RL20 RL23 RL19 RL22 RL24 RL21 RL20 RL23 RL19 RL63 RL62 RL60 RL61 RL55 RL63 RL62 RL60 RL61 RL55 Figure 7.2 - 8-Tributary Daisy Chain Switch Module 40-792: Component Layout 2MBit/s 75Ω 8-TRIBUTARY DAISY CHAIN SWITCH 40-792 Page 7.2...
