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 Technologies.
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.
