• Sizing
- Maximum no. of P8236’s that can be connected to a P8136 via the SLAVE LINK line (33): 5
- Maximum no. of P8136’s that can be connected in a system via the MASTER LINK line (20): 6
- Maximum length of the connecting line between the P8136 and the last P8236 connected to its SLAVE LINK line (33): 1 km (if the P8236’s
are distributed on 2 lines, this refers to the sum of the lengths of both lines)
- Maximum length of the MASTER LINK connecting line (20) between the first P8136 and the last P8136: 1 km

It must be stressed that the sequence of connection between the various different masters and/or between the various different slaves of a
given line is not conditioned in any way by their addresses. The tables show the signals and the pinouts of the connectors.

CONNECTIONS BETWEEN MASTER AND SLAVE
• Master/Slave
The P8136 Master Unit and any P8236 Slave Units are connected to one another by means of the SLAVE LINK IN/OUT link (33). This enables
data to be exchanged between the Slave Units and places the audio signal of the Master Units connected to the P8136 in common. The SLAVE LINK
(33) carries both the audio signal of the master stations and the music signal of the source selected on the P8136. In systems with no P8236 slave
units the SLAVE LINK connection (33) is not used. The P8136 – in its
slave
section – and the P8236 each have a dedicated internal jumper for
setting the end-of-line load for the SLAVE LINK connection, depending on the number of lines connected to the 2 IN/OUT sockets that is to say on
its position in the sequence according to which the Slave Units are connected. Adjustment is necessary above all for connections over long distances
(about 200-300 metres upwards).
CN106 – CLOSED – Connection of 1 line to own SLAVE LINK socket (default for P8136)
CN106 – OPEN – Connection of 2 lines to own SLAVE LINK socket (default for P8236).
• Master/Master
The various P8136 Master Units are connected to one another by means of the MASTER LINK IN/OUT link (20); this enables data to be exchanged
between the various different Master Units and enables them to call any zone that is available throughout the whole system. MASTER LINK (20)
carries both the audio signal of the master stations and the music signal of the source selected on the P8136. In systems consisting of a single P8136
the MASTER LINK connection (20) is not used. The P8136 has a dedicated internal jumper for setting the end-of-line load for the MASTER LINK
connection, depending on the number of lines connected to the 2 IN/OUT sockets, that is to say on its position in the sequence according to which
the various Master Units are connected. Adjustment is necessary above all in the event of long-distance connections (from about 200-300 metres
upwards).
CN306 – CLOSED – Connection of 1 P8136 to own MASTER LINK socket (end-of-line Master Unit)
CN306 – OPEN – Connection of 2 P8136’s to own MASTER LINK socket (default setting).
