EverFocus ECOR 264-8/4 D2 2 RS-485 socket pin assignment, EKB-500 connection to several DVRs

A RS-485 distributor can also be used to increase the maximum number of devices on the bus as well as the total range. Each distributor output provides another RS-485 bus. This allows each output to extend an additional 1200m, and it also enables the additional connection of 31 further devices to each output (the output itself represents one device).

The maximum system expandability depends on the RS-485 address range of the installed devices.

System expansion with RS-485 signal distributor

ATTENTION: EDA997A signal distributors are unidirectional! This means that the signal only flows from the input towards the outputs. Therefore, e.g. the interconnection of several keyboards is not possible with these types of signal distributor!

+ I

The RS485 pin assignment is as follows:

1.8.3EKB-500 connection with network patch cable

For a simple, short distance installation, recorder and keyboard can be connected directly using a standard CAT5 network cable with an 8-pin connector at only one end, and at the other end the Pin 3 wire connected to RS485 “+” (plus) and the pin 6 wire connected to RS-485 “-“ (minus).

1.8.4EKB-500 connection to several DVRs

For long distance installations connecting several DVRs, please use an EDA997A signal distributor to connect. For further details on keyboard connection, please refer to the EKB-500 manual.

RS-485 port communication settings are configured in the I/O CONTROL menu (Section 5.10.4 System Setup: I/O - control).
