Connecting the KT-400 Ethernet Four-Door Controller

Connecting the VC-485 or the USB-485 to the RS-485 Bus

Connect the RS-485 cable to (COM1) + 485 - and the RS-485 signal ground to the 12 VDC AUX - (negative)

Controllers are linked together through their RS-485 terminals. The maximum communication loop length is 1.2 km (4,000 ft) using appropriate cabling. The RS-485 communication loop should be wired with Ethernet Category 3 double twisted pair network cable or better. The RS-485 loop can operate from 1200 to 115200 Bauds under normal conditions. Intermittent communication problems or erratic operation may require network speed drops to 9600 or 19200 Bauds. Varying the network speed does not perceptibly change the operation speed of the system.

Note 1: Most installations should be set to 38400 Bauds.

Note 2: Connecting several KT-400 at a single point is not recommended neither are splitters or spider web (star) networks.

Note 3: If the 12 VDC - is already used, the RS-485 signal ground can be connected to the other GND terminals on the KT-400.

The EGND (earth ground) terminal cant be used for signal ground, only use the GND and 12 VDC - (negative) terminals for signal ground.

Note 4: There is no end-of-line resistor to install on the RS-485 COM1 terminals on the last KT-400 controller of a loop.
