Congratulations on your purchase of the 4x1 HD-SDI Switcher. Your complete
satisfaction is very important to us.
Switches between four HD-SDI Sources to one HD-SDI display.
The 4x1 HD-SDI Switcher is unique in its ability to connect one HD-SDI display to four
HD-SDI sources. You select from multiple sources using the IR remote control that
comes with the unit or RS232. Source switching is completed swiftly and high definition
video up to 1080p is supported.
SDI
SDI (serial digital interface), used primarily in broadcasting, converts and transmits digi-
tal video through SDI connectors. It enables video sources to process high definition,
high quality video.
How it works
Connect your HD-SDI sources and the one HD-SDI display to the 4x1 HD-SDI Switcher.
When all the equipment is powered and connected, switching can begin.

1. Remove battery cover from the back of the RMT4-IR remote.
2. Verify that dip switches 1 & 2 are in the down (OFF) position.
3. Insert the battery, hold the battery so that you can see the positive side facing up.
The side that is not marked must be facing down.
4. Test the RMT4-IR remote by pressing ONLY one button at a time. The indicator light
on the remote will flash once each time you press a button. WARNING: Do not press
multiple buttons simultaneously and do NOT press buttons rapidly. These actions will
cause the remote to reset and steps 1-4 will have to be repeated.
Note: The RMT4-IR ships with two batteries. One battery is required for operation, the
second battery is complimentary.

DIP SWITCH GUIDE
if you are experiencing Infrared interference, you can change the IR code on the
Remote and the 4x1 HD-SDI Switcher itself.
To change the IR code on the RMT4-IR, simply remove the battery cover and find the 2
dip switches just above the batteries. These switches correspond to a set of switches
on the 4x1 HD-SDI Switcher.
To change the IR code on the 4x1 HD-SDI Switcher, look under the unit and find a
silver sticker. Beneath this sticker is a group of 4 dip switches. The first 2 switches
(labelled 1 and 2) correspond to the 2 switches found on the RMT4-IR remote control.
The following are the 4 Infrared channels possible for both the RMT4-IR and the
4x1 HD-SDI Switcher. The dip switches on both the remote and the switcher itself must
match in order to be operational.
