3.7Connecting the SEG-1 to a Max 3 System (RS-485)
You can also use the SEG-1 to connect your Max 3 or MiniMax 3 system to your LAN/WAN. Follow the instructions below and refer to the diagram.
Run your RS-485 cable between terminal strip TS1 on the SEG-1 to TS3 on the backplane as shown in the diagram. You must also connect each module to the backplane by connecting the 3-conductor wire harness supplied with the Max 3 from P5 to the RS-485 connector underneath each module on the backplane (J1 through J4).
To connect additional backplanes to the system, simply connect TS3 on the first backplane to TS3 on the next backplane as shown below. The SEG-1 is only required on the first backplane of the system (up to 64 doors Max; if you require more doors an additional SEG-1 is required).
Note: The maximum distance between any backplane and the SEG-1 is 4000 feet using 24AWG, shielded, two twisted-pair telephone cable with a shunt capacitance of 16 pF/Ft.
