How to Setup NKB1000 via RS485

For DH-NKB1000, DH-KBD1000, or DH-KB1000

  • NOTE: RS485 transmission distance is 1200 m(9600bps)

How to wire the NKB1000's RS485 port:

1. From the PTZ's RS485 harness (or NVR) wire the positive to the positive and the negative to the negative. This picture will show a connector used as a junction for the PTZ to the CAT 5.E cable. (PTZ- Orange to CAT 5.E Blue, and PTZ Yellow to CAT 5.E White and green stripe)

  • From PTZ RS485 Harness

OR

  • From NVR/DVR/HCVR RS485 connector

2. On the NKB1000's back side connect and wire in a 2 prong junction connector, With A1 (CAT 5.E White and green stripe aka Yellow on PTZ's RS485 harness) and B1 (CAT 5.E Blue aka Orange on PTZ's RS485 harness)

RS485 Types of connections

  • There are several ways to wire the RS485 connection on the NKB1000:

1.RS485-RS232 Switch Boxes You can user one RS485 to RS232 switch box (provided) connect with DVR RS232 port One RS485 bus can connect with thirty-two RS485-RS232 switch boxes,one RS485-RS232 switch box can connect with twelve DVRs

2.Multi-keyboard link via RS485: You can use the following figure if you are connecting multiple keyboards via RS485 port. The last converter on RS485 port must be short circuited. (E.g.: open converter). See the image below, you need to change [1-2] short circuit to [2-3] short circuit.
