5.14 Video mu ltiplexer Videotec SP16C

5.14.1 Description

The SP16C 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 also possible to control the multiplexer indirectly, using a new generation video matrix (EKR-8/4, EKR-16/4).
This type of control is described in § 5.15 - Controlling the multiplexer using a video device, page 48.

5.14.2 Connexion

5.14.2.1 Cable
The connection is of the RS485 type (one-way) and the maximum distance between keyboard and multiplexer is
1200 metres.
5.14.2.2 Multiplexer se ttings
The multiplexer can only be set up using the local multiplexer keyboard.
Set the right baud rate and the multiplexer identification number.
See the respective manual.
5.14.2.3 Keyboard set tings
While the keyboard is being set up, the

• press
Each command sent by the keyboard corresponds to the lighting up of an LED on the local multiplexer
keyboard.
Warning! If the number of the multiplexer unit does not coincide with the commands sent from the
keyboard, they will be ignored.
