For networks longer than 30 feet, you must terminate the network at each end for it to work reliably.
The network is polarity dependent, so you must connect pin 3 to pin 3 and pin 4 to pin 4. Do not
reverse the polarity of the network.
Do NOT use the DC 12V power leads in the RS-485 cable UNLESS it is to be used on a one-to-one
connection between a unit with DC 12V power and a unit with no DC 12V power. For example, from
a multiplexer directly to a keyboard that does not have its own power source.
In all other circumstances, such as multi-dropped multiplexers, do NOT use the DC 12V power
leads in the RS-485 cable.
If you choose to power another unit (e.g. a single keyboard), you can do this up to 30 feet from the
multiplexer. Use a 4-core shielded cable, equivalent to Belden 8723.
For more detail on the remote keyboard, refer to the JVC-KB Remote Keyboard instruction sheet.
