5.7 Switchers Linxs LXRPS42A and LXRPS82A

5.7.1 Description

Switchers LXRPS42A and LXRPS82A are products for professional use in applications for security and
surveillance and dedicated to the management of video signals. The LXRPS42A and LXRPS82A models differ
only in the number of possible video input connections, 8 and 4 respectively; there are two video outputs, one of
which can be managed directly by a VCR. They are used to control the usual switching, alarm management and
on screen menu programming operations. Refer to the switcher manual for further information on this subject.

5.7.2.1 Cable
The communication cable is standard, as described in § 3.3 - Standard connection cable, page 8.
5.7.2.2 Switcher sett ings
The baud rate of the switcher can be selected using the bump contact JP1 inside the switcher:
• bump contact open: 9600 baud (default status)
• bump contact shorted: 1200 baud
Operations to modify the baud rate should be carried out after disconnecting the power supply to the switcher.
Refer to the respective manual.
