3.4 One control keyboard per line

Connection is performed by means of one standard connection cable, which is described in the previous paragraph.

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 11, identify the two devices which represent the line ends and correctly terminate them (to terminate the EKR-KB1 keyboard, see § 2.5 - Dip switch, page 10).

Particular attention must be paid for the length of the stubs.
