Install KIT-401T and Mount KIT-400R
Install KIT-401T
Insert the device into the in-wall box. Note that first you need to connect the HDBT cable (and power – if powering via the transmitter) and connect the parts as shown in the illustrations below:
EU/UK Version
US-D Version
DECORA® design frames are included in US-D models. DECORA® is a registered trademark of Leviton Manufacturing Co., Inc. We recommend that you use any of the following standard 2 gang in-wall junction boxes (or their equivalent):
- US-D: 2 gang US electrical junction boxes.
- EU: 2 gang in-wall junction box, with a cut-hole diameter of 2x68mm and depth that can fit in both the device and the connected cables (DIN 49073).
- UK: 2 gang in-wall junction box (BS 4662), 135x75mm (W, H) and depth that can fit in both the device and the connected cables.
- EU/UK: 2 gang on-wall junction box (use the recommended Kramer on-wall box available at www.kramerav.com/product/KIT-401T).
Mount KIT-400R
Install KIT-400R using one of the following methods:
- Rhais cov roj hmab ko taw thiab muab tso rau qhov chaw ntawm tiaj tus.
- Fasten 2 brackets (included) on each side of the unit and attach them to a flat surface (see www.kramerav.com/downloads/KIT-401).
- Mount lub tsev nyob rau hauv ib tug khib siv qhov kev pom zoo rack adapter (saib www.kramerav.com/product/KIT-401).
Ceeb toom:
- Xyuas kom meej tias ib puag ncig (piv txwv li, qhov ntau ntawm huab cua sov & cua txaus) yog qhov sib haum rau lub cuab yeej.
- Zam kev thauj khoom tsis sib xws.
- Kev txiav txim siab tsim nyog ntawm cov khoom siv npe npe yuav tsum tau siv kom tsis txhob muaj overloading ntawm circuits.
- Lub pob ntseg txhim khu kev qha ntawm cov khoom siv sib dhos yuav tsum tswj xyuas.
- Qhov siab tshaj plaws mounting qhov siab rau cov cuab yeej yog 2 meters.
Txuas inputs thiab outputs
Always switch OFF the power before connecting to your KIT-401.
Connect the audio output:
Yuav kom ua tiav qhov kev ncua deb ntxiv, siv cov Kramer cable xav kom muaj nyob ntawm www.kramerav.com/product/KIT-401Cov. Siv cov kab hluav taws xob thib peb yuav ua rau kev puas tsuaj!
Wiring the RJ-45 connectors
This section defines the TP pinout, using a straight pin-to-pin cable with RJ-45 connectors. For HDBT cables, it is recommended that the cable ground shielding be connected/soldered to the connector shield.
Setting the KIT-401T OPTION DIP-switches
A switch that is down is on; a switch that is up is off. By default, all the switches are up (off). After changing a DIP switch you must power cycle the device to implement the change.
- DIP-switch 1 set to off (up).
- DIP-switch 2 set to off (up).
Audio Switching Selection
| DIP-switch 3 | DIP-switch 4 | Kev xaiv suab nkag | |
| Off (up) | Off (up) | Automatic – Priority selection: Embedded HDMI ” analog Audio In (high to low priority). | |
| Off (up) | On (down) | Automatic – Priority selection: Analog Audio In ” embedded HDMI (high to low priority). | |
| On (down) | Off (up) | Embedded HDMI. | |
| On (down) | On (down) | Analog Audio In. |
Txuas lub hwj chim
KIT-401 uses a PoC (Power over Cable) system, meaning that the system is powered by connecting the 12V adapter to either KIT-401T or to KIT-400R. Do not connect power to both devices. Safety Instructions (See www.kramerav.com for updated safety information) Caution:
- Txog cov khoom lag luam nrog cov chaw xa khoom txuas thiab GPI \ O chaw nres nkoj, thov xa mus rau qhov ntsuas tau tso cai rau kev sib txuas sab nraud, nyob ib sab ntawm lub davhlau ya nyob twg lossis hauv Phau Ntawv Qhia Siv.
- Tsis muaj cov tswj hwm kev pabcuam hauv cov chav ua haujlwm.
Ceeb toom:
- Failure to use PoC and power connector correctly may destroy the devices!
- Siv cov hlua hluav taws xob tsuas yog tau txuas nrog chav ntsuas.
- Txuas lub hwj huam thiab tshem tawm ntawm chav tsev ntawm phab ntsa ua ntej nruab.
Operate KIT-401
Operate KIT-401 via:
- Nyob deb, los ntawm RS-232 serial commands kis los ntawm ib tug kov screen system, PC, los yog lwm yam serial maub los.
- embedded web nplooj ntawv ntawm Ethernet.
- Remote control switches.
