Installing The Rui Motherboard - Simplex 4100ES Installation Manual

• Up to 4 RUI cards in the 4100 Control Panel can be used for distributing transponder wiring in different directions or for supporting
different wiring requirements (such as using a Class X RUI for serial annunciators).
• Up to 31 MINIPLEX transponders can be controlled from the 4100 Control Panel, and can be distributed as required among the RUI
cards.
• "T" tapping is allowed for Class B communications only (Class X wiring does not support "T" tapping).
• *Wiring from RUI cards is a minimum of 18 AWG twisted, shielded pair.
• The maximum wiring distance from the 4100 RUI card to a MINIPLEX transponder is 2500 feet (762 m). For Class B wiring, this can be
extended to 10,000 feet (3 km) maximum if "T" tapping is used.
• Voice and telephone wiring for 4100-8210 systems is via separate twisted, shielded pairs.
• 4100U system cards are not compatible with 4100 miniplex transponders that are controlled by a 4100 RIC II card.
*The RUI+ has the same limitation as the RUI, except shielded wire is not required.
13.4 Installing Modules into Back Boxes
This section contains guidelines and instructions for mounting the RUI and RIC II modules into 4100 back boxes.
• The RUI motherboard mounts into the CPU bay or, if necessary, an expansion bay.
• The RIC II mounts into expansion bays only.
13.4.1 Guidelines
Review the following guidelines before installing a motherboard into a cabinet.
• If a power supply is installed in the bay, it must be installed on the far right of the bay and any relay modules must be installed in the
slots immediately to its left.
• Relay cards must be installed in the rightmost possible slots. This is necessary to allow for the proper routing of non-power limited
wiring (typically 120 VAC wiring), which could be connected to a relay module.
13.4.2

Installing the RUI Motherboard

Mount the RUI motherboard (562-799 or 562-856) in a master controller bay as described below.
1. Orient the motherboard with the connector labeled J1 on the right and the header labeled P1 on the left.
2. Match the connector on the previously installed motherboard with the pins on the motherboard you are installing. Slide the
motherboard to the left until the pins are completely inserted in the connector of the previously installed motherboard. If you are
installing the leftmost board, the pins will remain unconnected.
3. Secure the motherboard to the chassis with four torx screws.
Note: RUI motherboards may also be installed in expansion bays.
