More Than Two Devices On The Same Line - Videotec Dck Bedienungsanweisung

3.5 More than two devices on the same line

The presence of more than one keyboard on the same communication line requires the use of Rjjack boxes, to
be connected in the correct way. As specified in § 3.2 RS485 and system types, page 7, identify the two devices
which represent the line ends and correctly terminate them (to terminate the DCK keyboard, see § 2.5 - Dip
switch, page 6).
Particular attention must be paid for the length of the stubs.
