1.0 Introduction

Product Description

The GEM-EX is comprised of the GEM-EX-S sender and the GEM-EX-R receiver.

The system is used to extend USB 2.0, Audio, dual RS-232, and dual display

HDMI video supporting various resolutions including 1080p @ 60 Hz and 4K

UHD @ 30 Hz. These signals are extended to one or more receivers up to a

distance of 100 m (328 ft.) over a single CAT6 cable.

The sender features two HDMI inputs, one USB input, one analog audio input,

and a dual-port capable RS-232 port for connection to a dual-head PC. The audio

input is embedded into HDMI A. It provides two local HDMI outputs

(corresponding to the two HDMI inputs) and features an internal USB hub with

two local USB outputs. Additionally, there are two separate RJ45 output ports to

extend these signals to multiple remote locations.

The receiver provides two HDMI outputs, 6 USB ports, an analog audio output,

and a dual-port capable RS-232 port. Two of the USB ports are labeled for use

with keyboard and mouse; however, they can also be connected to other USB

devices such as KVM switches or touch-screen displays if desired. The audio

output is de-embedded from HDMI A.

For connection of other USB devices such as printers or scanners, four

additional general-purpose USB 2.0 ports are available. For security purposes,

USB memory devices are not supported by default. If you want to enable USB

memory support, please contact Hall Research.

In a setup with one Sender going to only one Receiver, the USB ports

automatically pair with the Sender. However when there is more than one GEM-

EX Receiver connected to the same Sender, only one Receiver can be paired at a

given time. Pairing is accomplished using a push button on the front panel of the

Receiver. A corresponding LED next to the button indicates USB pairing status

with the Sender.

Each Receiver features an RJ45 “LINK OUT” port that can be daisy-chained to

down-stream Receivers. All signals are re-buffered, so the LINK OUT port can

drive cables to 100 meters long.

It is important to note that the RJ45 output ports (on the Sender or the

Receiver), can also be connected to ULTRA-V Receivers. ULTRA-V Receivers

provide only one video output and no USB. The ULTRA-V Receivers show Video

A by default, however, they can be configured to display Video B if desired.

Please refer to the ULTRA-V User’s Manual for further details.

DisplayPort Adapters

While HDMI is the most widely adopted video standard, there are a number of

computer and display manufacturers that rely on DisplayPort for higher

resolutions such as 2560 or 4K. Hall Research offers 4K compatible adapters

to convert between these two video standards.

To connect to a source (PC) with Displayport output, use GC-DP-HD.

Model GC-DP-HD: DisplayPort source to HDMI output

Virtually all monitors and TVs have HDMI (or DVI) inputs, but if your display

only has Display port input, the following adapter converts HDMI to DP.

Model GC-HD-DP: HDMI source to DisplayPort output

NOTE These adapters are unidirectional. For example, the

DisplayPort to HDMI adapter cannot convert an HDMI signal

to DisplayPort.

Single Video Display Receiver

In cases where only a single video display is required, an ULTRA-V-R Receiver

can be connected to either the GEM-EX Sender or Receiver. The Receiver will

display the video coming from HDMI A by default, or it can be configured to

display video from HDMI B if desired. Please refer to the ULTRA-V User’s

Manual for more information.

Model ULTRA-V-R: Single HDMI output Receiver

RS-232 Baud Rate Programming and Dual-Port Support

The RS232 ports on the GEM-EX-S and GEM-EX-R have different baud rates by

default. RS-232 Port A defaults to 9600 baud. RS-232 Port B defaults to 115200

baud.

These can change to any standard rate between 2400 and 15200 using free PC

GUI software. Both sender and receiver are programmed separately.

The GEM-EX has a dual-port RS-232

output, supporting a second RS-232

extension.

This requires the use of adapter cables

CA10233 and CA10224, sold separately.

NOTE Baud Rate Conversion: When the GEM-EX-S and GEM-EX-R

are set to different baud rates; they will automatically

convert between the two.
