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!
1.9.2 RS-485 socket pin assignment
The RS485 pin assignment is as follows:
1.9.3 EKB-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).
1.9.4 EKB-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).
1.9.5 Speed Dome Installation
Speed dome or telemetry receiver pan/tilt/zoom control is available through web browser or the optional
PowerCon software if the DVR is connected to a network. Local telemetry control is provided by USB -
mouse control or by the optional EKB-500 keyboard.
Supported protocols: EverFocus, Pelco-D, Pelco-P, Samsung, Transparent
Required DVR settings: RS-485 receiver address in CAMERA menu
(Section 4.3)
RS-485 parameters and protocol in the I/O CONTROL menu
(Section 5.10.4)
ATTENTION: Some Pelco-D / -P protocol domes and receivers require an address offset of -1, i.e. the
address assigned to the dome / receiver in the DVR camera menu must be 1 below the address set in the
dome / receiver itself!
