CTI Products, Inc. 1. MCN RYB-8 Relay Board Manual Introduction The MCN-RYB-8 board is a relay board accessory to the MCN Monitoring and Control Network product family. The MCN-RYB-8 board has the following features: • (8) DPDT Relays (Configured to switch circuit pairs). • Hi-reliability long-life sealed relays. • Relays rated for low-level (dry circuit) audio switching, up to 2A. • Selectable 600 Ohm terminations for the Normally Open, Normally Closed, or Common circuits (may be de-selected).
MCN RYB-8 Relay Board Manual 2. CTI Products, Inc. Circuit Description The MCN-RYB-8 board has 8 identical circuits. The following will describe the first such circuit.
CTI Products, Inc. 2.2 MCN RYB-8 Relay Board Manual Sub-Category Jumpers E1-E8 “A” Side When you use the MCN Relay Board with an MCN IOB module and the MCNRCD PC Software, you can use the “A” side of jumper blocks E1 through E8 to provide static sub-category status text selections. This will allow you to specify different status text messages (On/Off, Up/Down, Main/Standby, etc. as defined in the MCNRCD.CFG file) for different relays on the MCN-RYB-8 board.
MCN RYB-8 Relay Board Manual 2.4 CTI Products, Inc. 600 Ohm Termination Jumpers E9-E16 A selectable 600 Ohm termination is available for each relay. The termination is used in some telephone line applications when you need to terminate an unused phone line. Jumper blocks E9 to E16 control the terminations.

CTI Products, Inc. 3.3 MCN RYB-8 Relay Board Manual Relay Input Connections -- J2 The relay input connections appear on a 50-pin female micro-ribbon telco style connector, J2. The relay input connector is laid out to match the MCN IOB module pin-for-pin. J2 can be connected to the IOB module directly through a 25pair straight-through male to male cable. Since the MCN CIB module was originally set up to match the Digitac P805 pinout, the signals are a bit scrambled.
