RYG Alzatex Wiring Basics Common Cable Types Used Crossover Flat 4 or 6 Wire Phone Cord RJ-11 RJ-11 CAT-5 (T568B) 8 Wire Network Cable RJ-45 RJ-45 Typical Display Port Connections Alzatex, Inc. www.alzatex.com D2-60 GND D1-RX +V D3-TX J2 + J1 J6 Cat-5 RJ-45 J7 TX-422 RX-422 D2 D2 D2 IR DE + J5 D2-60 GND D1-TX +V D3-RX D2 D1 D3 D4 GND +V J3 J3-RSSR D3 - Count Up D1 - Reset D2 - Stop/Down D4 - Start SYNC TX RX RX DE Model DSP-500 RX RSSR TX TEST Power Power = 13-24 VAC or 15-24 VDC The TX, RX, TX-422 and RX-422 ports are for serial data connections between Timers and Displays. The TX and RX ports are RJ-11 type and use 4 wire phone cords. They are used for short distance connections (<100ft). The TX-422 and RX-422 ports are RJ-45 type and use 8 wire CAT-5 network cable. They are used for longer distance connections. TX (Out) connects to RX (In) or TX-422 (Out) connects to RX-422 (In). The RSSR port is RJ-11 type and uses 6 wire phone cords. It is for digital switch closure to GND type inputs and is usually connected to simple keypads or push buttons. RX-422 88:88 Display TX-422 RX-422 RYG CAT-5 Cable RJ-11 Crossover 4 Wire Phone Cord RX 88:88 Display TX TX-422 Standard 4 Wire Phone Cord RJ-11 Displays can be daisy chained as long as the data flows from TX (Out) to RX (In) and the power requirements are met. Power can be applied to units at each end of long cables if the voltage drop is too great. A distribution hub can be used for systems with a large number of displays. CAT-5 Cable Standard Flat 4 or 6 Wire Phone Cord RX Master Timer 88:88 TX Power in Wall Power Supply Always apply power to largest display in the system. Here is an example meeting timer system. Use Standard 4 wire phone cords when running from a timer to a display, Crossover 4 wire phone cords when running between displays, or CAT-5 cables when running long distances. Power as well as Data is sent through the cables, and each unit has self resetting fuses. So if a section goes dead try changing power connection or add more power supplies.
