11.1 RS-485 REMOTE CONTROL
The new standard EverFocus EDSR remote control protocol allows sophisticated installations with
DVR remote control at different installation sites.
EDSR remote control is supported by the keyboards KS KBJ (with 3-axis joystick and 2 additional
RS-485 ports for telemetry control with independent telemetry protocols) and KS KBK (no telemetry).
Up to 32 units are allowed in the RS-485 bus. The RS-485 bus requires serial wiring with 2-wire
shielded twisted pair cable (“daisy chain”). Maximum cable length of the bus is 1200 m.
Star wiring is only possible with additional RS-485 distributor.
Mixed installation is possible with following recorder types:
EDSR 100 M, EDSR 400 M, EDSR 600, EDSR 900, EDSR 1600
For installation details, please refer to the KS-KBK and KS-KBJ keyboard manuals.
