USB support
AdderLink XD522 units provide support for a wide range of USB devices via four
ports on the receiver unit. Three of the ports (labeled A) support low/full speed
(v2.0) USB and are made possible using Adder’s proprietary True USB Emulation
technique which is specifically designed to overcome the problems usually
encountered when remotely connecting USB keyboards and mice. The fourth
port (labeled B) provides Hi-Speed (v2.0) USB with transfer rates up to 480Mbits/
sec.
Audio support
The AdderLink XD522 units can transfer analog and digital audio signals across
the CATx cable link. Standard analog audio is supported through 3.5mm jacks
on the transmitter and receiver units: Line In/Out on the transmitter; Line In/Out
plus Microphone/Headphones on the receiver.
The three A ports support only USB keyboards and mice.
Port B provides Hi-Speed USB support for mass storage and isochronous devices.
Note: Availability of the fourth (B) USB port depends upon the use of CATx Link
B which is used solely for the transport of Hi-Speed USB signals.
Additionally, the Line In socket on the transmitter and the Line Out socket on
the receiver are dual purpose. They can accept either 3.5mm analog jacks or
mini-TOSLINK optical fibre connectors. The latter provide access to the optical
S/PDIF (Sony/Philips Digital InterFace) capabilities supported by
the AdderLink XD522 system, which transmits PCM (Pulse
Code Modulation) audio at 96KHz. The digital and
analog channels run independently alongside each
other via the CATx link.
Third party adaptors (not supplied) are
available to convert between the
mini-TOSLINK connections used
on the AdderLink XD522 units
and the more common full size
TOSLINK connectors found on
many audio/visual devices.
Serial communication support
The AdderLink XD522 transmitter and receiver both have serial Options ports
which are used for firmware upgrades but are also available during normal use
for transferring high speed serial data across the CATx link. This means that
you can connect the serial port of the Host computer to the transmitter and
any serial device to the receiver. These can then freely communicate at up to
115,200 baud across the transparent link. No serial configuration is required on
the AdderLink XD522 units as they merely pass through the serial signals.
