INTRODUCTION
Thank you for purchasing the RMT-MATRIX-444 and/or the RMT-2-CAT5.
The RMT-MATRIX-444 is a powerful tool that can be used with the EXT-DVIKVM-
444. It will allow you to remotely switch your sources. If your remote station is
located in another room, you can easily switch to another source by pressing
one of the four pushbutton switches on the RMT-MATRIX-444. This box easily
connects to the EXT-DVIKVM-444 by one CAT5e cable. You can use up to four
RMT-MATRIX-444 units with the EXT-DVIKVM-444 to have the ability to switch
at all four remote workstations.
The RMT-2-CAT5 now gives your Gefen 4x4 Matrix box the power of remote
switching. The RMT-2-CAT5, in conjunction with up to four RMT-MATRIX-444
units, will extend your ability to manage your sources at each remote display. It
will work with any of our 4x4 matrix untis listed below. Your remote switching is
easily setup by using one CAT5e cable from the RMT-MATRIX-444 to the RMT2-CAT5, and then connecting the RMT-2-CAT5 to your matrix switcher by using
a serial cable. You can now switch your sources at each display without ever
having to switch locally again.

USING THE RMT-MATRIX-444
USING THE RMT-2-CAT5
1. Connect a CAT5/6 cable between the RMT-MATRIX-444 and one of the
CAT5 ports on the rear of the DVIKVM-444N. The ports are labeled as RMT A,
B, C, and D and correspond with DVI out ports 1, 2, 3, and 4.
2. Use the contact buttons on the RMT-MATRIX-444 to switch between the
different inputs connected to the DVIKVM-444N. Switches A, B, C, and D
correspond to sources 1, 2, 3, and 4. Optionally, you can use a RMT-4IR
(infrared remote) in conjunction with the RMT-MATRIX-444 to switch inputs
from a distance.
1. Connect a CAT5/6 cable between the RMT-MATRIX-444 and one of the
CAT5 ports on the rear of the RMT-2-CAT5. The ports are labeled as RMT 1,
2, 3, and 4, which correspond with any of our matrixs’ 1, 2, 3, and 4 display
outputs.
2. Connect a serial cable (must not be a null modem serial cable) between the
RMT-2-CAT5 and the compatible Gefen matrix product.
3. Use the contact buttons on the RMT-MATRIX-444 to switch between the
different inputs connected to the compatible Gefen matrix product. Switches
A, B, C, and D correspond to sources 1, 2, 3, and 4 on any of our matrix units.
