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 485 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)

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 RS 485 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.
