RS232 via the front-panel socket
The front-panel RS232 allows you to configure the loudspeaker
to suit its role in the system, or perform firmware updates.
A cable suitable for connecting to the front-panel RS232 socket,
terminated in a female DB9 plug, is available from authorised
Meridian dealers: Meridian part number: PA10824
The socket accepts the longer version of the three-way, 3.5mm
(1/8 inch) minijack plug, eg Schurter part no. 4802.1300:
The standard minijack plug commonly used on headphones and
ear-buds with a shorter 14mm plug cannot be used:
RS232 via the SpeakerLink input
If the loudspeaker is installed behind a projection screen or
under a fabric wall-covering, the front-panel RS232 socket may
be inaccessible. In this case the SpeakerLink input cable, which

also carries RS232 connections, can be used to configure the
loudspeaker.
•
Temporarily disconnect the SpeakerLink cable from the product
feeding the loudspeaker.
•
Connect the RJ45 plug into an RJ45 Inline Coupler to provide
an RJ45 socket.
•
Connect the RJ45 socket to an RJ45 to RS232 cable.
An RJ45 to RS232 cable, terminated in a female DB9 plug, is
available from authorised Meridian dealers: Meridian part
number SK1622.
Where loudspeakers are daisy-chained, access to the
SpeakerLink input of the downstream loudspeakers can be
provided by routing all SpeakerLink feeds through RJ45 couplers
located in the rack.
