DL-RMKTC2H-W Installaon Guide
The Digitalinx DL-RMKTC2H-W is a mul-funcon AV distribuon system designed to provide
HDMI video switching, system control, video extension and analog audio amplicaon in
a convenient kit. Ulizing the Valens Colligo VS2110 series chips, power, control, video up
to 1080p, and audio are transported over a single 30m (98 ) solid core Category 5e cable
between the wall plate transmier and the receiver. The wall plate control module connects
to the wall plate transmier with a second Category 6 cable. All the power needed for the
system is provided by the receiver. Addionally, the receiver features a built-in web GUI for
control and analog audio de-embedding to a built-in 2x20 wa stereo amplier.

units.
RS232 Wiring
Connect the display RX signal to Tx on
the DL-RMKTC2H-W receiver Connect
the display TX signal to Rx on the DL-
RMKTC2H-W extender.
To ensure proper performance of the DL-RMKTC2H-W, it is recommended that you use solid
core Category 6 F/UTP cabling at a minimum between control keypad and transmier and
between transmier and receiver. Category 5e F/UTP may perform well but may not support
power over HDBaseT reliably.
When using shielded category cabling ALWAYS...
....use shielded connectors
....properly ground the category cable
