1. Version 2008 04 02 Multi XR Contact Multiplexer for UPS Interfaces User manual GENEREX Systems GmbH Germany Copyright 2012 Version 2008 04 02 Function Multi XR is a port multiplexer for ups relays contacts with Novell and AS400 configuration It has 5 10 computer ports and an extension port to daisy chain additional Multi XRs It supports the signals AC fail battery low on bypass summery alarm In addition it allows a configurable AND connected ups shutdown from one or more computers For shutting down Windows systems or systems that need time to completely shut down after triggering the UPS shutdown the ups shutdown forward can be delayed by 1 3 or 10 minutes When AC power returns before a ups shutdown has been executed the shutdown signals are cleared and the shutdown logic goes back to wait status The extension port only Multi XR10 allows you to daisy chain additional Multi XR and integrate their shutdown functionality CAUTION ALL MULTIPLEXERS MUST BE SUPPLIED OVER THE UPS POWER OUTLET BECAUSE OTHERWISE A SECURE OPERATION IS NOT POSSIBLE IN CASE OF A PUBLIC MAINS POWER FAIL THE POWER FAIL INPUT SIGNAL MUST BE CONFIGURED TO WORK WITH THE POWER FAIL CLOSED CONTACT OF THE UPS SEE DIP SWITCH SETTINGS The output ports are isolated against each other and totally volt free The direction of the signaling voltage does not matter because the multiplexer works with real r2. e pin for storing them For the connections and jumper positions see the table below For a correct pin configuration at the ups connector it is necessary to understand the function of the jumper field Version 2008 04 02 Put the Multi XR in a position that the rear panel with the connectors points at you The jumper field is organized by rows and columns Each row represents one of the functions i e power fail Each column connects to one pin on the ups connector For the correct configuration of the input connector each signal must be connected to the connector pins rows B E amp H at the right position column To give an example the positions for the default configuration are grayed in the table Jumper field ups connector function FR row pin number at ups connector ane ook a epepey era e URETS a ae oe oe ian oe oe Pi E ie Ue ee HE a EEN HE i a SEE On Bypass Shutdown configuration The shutdown functions and shutdown delay are configured with the DIP switches at the rear panel of the Multi XR 12 12345678 910 1 1 1 2 shutdown delay 2 1 2 10 shutdown at port 1 10 S1 S2 shutdown delay S1 1 0 minutes 1 minute 3 minutes Version 2008 04 02 The DIP switches 1 1 1 2 set the shutdown delay It can be set to 0 1 3 or 10 minutes to allow even slower systems to shut down before the ups shutdown is executed The switch
