Serial connection
The Options port on the rear panel of every AdderLink XD522 unit operates as a serial
connection that can either:
• Be used to update the rmware of the unit (see Performing an upgrade for details), or
• Provide an RS232 serial connection that is passed between the transmitter and
receiver.
Whenever the AdderLink XD522 units are not in upgrade mode, they are ready to
transfer serial data between them at rates up to 115200 baud. When serial devices are
attached to the Options ports on the transmitter and receiver, the units transparently
convey the signals between them - no serial conguration is required.
To connect serial devices
1 Use the supplied serial cable to link the Options port on the rear panel of the
transmitter unit with a vacant RS232 serial port on the host computer.

serial port
Link connections
AdderLink XD522 transmitter and receiver units are linked by either one or two
CATx cables at a distance of up to 150 meters (492 feet). The type and quality of the
CATx cables used are crucial to the mode of operation (please see the section Tips for
achieving good quality links). If Hi-Speed USB is not needed at the receiver then a CATx
link between the B ports of the units is not necessary.
IMPORTANT: The signals sent through the link cables are NOT compatible
with standard networking equipment and could cause damage if connected.
Do not connect the transmitter or receiver modules to any other networking
devices.
To link the units
1 Connect the CATx link cable from port A of the receiver unit to port A on the front
panel of the transmitter unit.
From link
port A on the
receiver unit
From link port B on the
receiver unit (required only
for transfer of Hi-Speed USB)
2 If Hi-Speed USB is required, connect the CATx link cable from port B of the receiver
unit to port B on the front panel of the transmitter unit.
Please see Appendix A for pin-out details of the Options port.
