5.10 Video mu ltiplexer Javelin/Hitron

5.10.1 Description

The Javelin/Hitron multiplexer allows the connection of 16 input videos, which are digitalized and shown as a
composite image at output. A spot service monitor supplies the display of one of the inputs.
Communication from keyboard to multiplexer is one-way. It is necessary to determine whether the connected
multiplexer is a black & white or colour model, since the specifications and protocols are different in the two
cases.
It is also possible to control the multiplexer indirectly, using a new generation video matrix from the SM series
(SM42A, SM82A, SM84A, SM164A). This type of control is described in § 5.12 - Controlling the multiplexer
using a video device, page 31.
5.10.2 Direct conn ection
5.10.2.1 Cable
The connection is of the RS485 type (one-way) and the maximum distance between keyboard and multiplexer is
1200 metres.
5.10.2.2 Multiplexer se ttings
The Javelin multiplexer is available in two versions that differ in their control protocol.
It can only be set up using the local multiplexer keyboard.
See the respective manual.
5.10.2.3 Keyboard set tings

It is only possible to connect one keyboard to each Javelin multiplexer, and therefore the identification number
of the keyboard is of no importance. More than one multiplexer can be controlled by the same keyboard, as long
as they are identified by different unit numbers.
