D. DIP Switch

Use DIP switches 1-6 (shown in Figure 1) to set the RS-485 network address.
Figure 3 Set the RS-485 address

Note: You must set the RS-485 address even if you are not using RS-485.

DIP switch 7: keep off.
DIP switch 8: Set open (off) to get an IP address from the DCHP server, and set closed (on) to set a fixed IP address using the TX3 Configurator software. The default setting is off.

For more information and the complete list of RS-485 addresses, see LT-980, the TX3 Card Access System Manual, on the Mircom website (www.mircom.com) or the USB flash.

E. RS-485

Connect the RS-485 input terminal to the RS-485 output terminal of another controller. See Figure 4.
Set the 120Ω switch ON (shown in Figure 2) if unit is used as first or last controller on RS-485 network. Otherwise set OFF. The default setting is OFF.

Note: Use twisted shielded pair.

F. USB Port

The USB port provides a connection to a PC, for configuring the Card Access System and upgrading the firmware.

G. Power

The Single Door Controller can be powered in three ways. Use only one of the power inputs.

Power over Ethernet (PoE) – use Cat 5 cable
12 VDC/15 W – use 18 AWG
24-48 VDC/15 W – use 20-18 AWG

H. Example Network Diagram

Use TX3-IP-NP-256 IP Gateway to connect TX3 devices to an Ethernet network. The IP Gateway is a bridge between RS-485 on the device side, and Ethernet on the network side.
