RS485 Transmission

The distance of RS485 transmission between 2 nodes depends on the baud-
rate. The table on the right side shows the maximum range of every baud-
rate, assuming a AWG24 wire-pair is used. Note the range might be shorter
than given here, since the cable quality or interferences may affect the
transmitted data, and cause invalid command.
In star-form connection, it might be necessary to use RS-485 Distributor, to
ensure the signal quality of the transmission.

Video Transmission

For video signal transmission, coaxial cable with 75 Ohm impedence is recommended. Depends on the cable type, the transmission
distance might be different:
Cable standard
Max. Distance (m /ft )
RG 59 /U
229m / 750 ft
RG 6 /U
305m/ 1000 ft
RG 11 /U
457m / 1500 ft

The actually transmission distance can vary from the data shown on the table left. It is
necessary to consider the environmental in fluences when planning the installation. If
the transmission requires a larger distance, you may use video-balun or fiber-transmitter
to extend the distance. Contact your local sales representative for further information.
