RJP(Remote Jack Pack)

RJP stands for Remote Jack Pack. The RJP is a hardware module that has different Audio Video inputs (A/V, S-Video,
Audio, PC and HDMI) and corresponding outputs. The corresponding output sources are connected from RJP to TV.
The RJP communicates with the TV via RS232. Hot Plug & Play is a function that allows hotel guests to connect an
external source to the RJP. The RJP communicates with the TV by sending messages regarding Active/Inactive sources.
The TV will switch to the Active external source according to the priority set by the User.
- You have to connect the HDMI of the RJP to the HDMI 1 port of the TV.
- When the TV is on, connect the TV and the RJP within 10 seconds.
The RJP can be returned to the factory default settings by pressing the A/V and HDMI buttons simultaneously
for 10 seconds. All LEDs blink 5 times to Acknowledge that the rest has been performed.
The RJP will automatically turn off any LEDs after 5 minutes to avoid unnecessary light pollution in the hotel
room. The LEDs that were turned off will turn on again if the guest touches any of the buttons and the 5 minute
timer will restart. If the guest then touches another source button, the TV will change to the selected source and
the corresponding LED will be lit.
After an RJP Reset or a TV Power OFF/ON, it takes approx. 10 seconds to establish communications between
the TV and the RJP.
The following table shows the approximate time in seconds to switch from the TV to the input source, based on
the priority.
Scenario 1: When no inputs are connected.
Source
AV
PC
HDMI
Scenario 2: When two or more inputs are connected and an Input source is disconnected and then reconnected.
Source
AV
PC
HDMI
E.g. If the RJP has all its live sources AV, PC and HDMI connected, AV is viewed as the highest priority. If the RJP is in
HDMI mode, and a guest removes and reconnects the AV, the minimum time required to switch to the AV is 6.5 seconds.
To connect audio (Ipod or Mp3), Music mode should be ON and Jack Ident detect should be OFF.
A/V, PC and HDMI input sources are supported.
