APPENDIX C: DEVICES WITH SERIAL/AUDIO OPTION

Serial Interface – Handling Multiple Serial Devices
The serial interface transmits/receives six signals (3 signals in each direction). Normally four
of these signals are used for hardware handshaking (in addition to Tx & Rx). However,
because each handshaking line can support signals up to 19,200 Baud it is possible to
configure the serial interface to handle up to three simple 2-wire (Tx/Rx only) serial links. To
do this you will need to construct a custom breakout cable. Please contact technical support
for further information. Select Xon/Xoff software flow control on the printer and CPU.
Audio Interface - Setup and Operation
The audio interface is line-level and is designed to take the output from a sound card (or other
line-level) source and be connected to a set of powered speakers at the other end of the link.
Stereo audio may be transmitted either way across the link (simultaneously). No setup is
required unless a microphone is connected to the Remote Unit. Connect up as follows:
•
Take the line-level output from your sound card (green connector) and connect to
‘Line In’ on the extender.
•
A set of powered speakers may be connected directly to ‘Line Out’ at the opposite
end of the link.
Audio Interface – Using a Microphone
A microphone may be plugged into the ‘Line In’ connector on the Remote Unit. There are
two ways of setting up a microphone:
•
The Local Unit’s ‘Line Out’ connection should normally be wired to the
microphone input (red) on your sound card. The sound card should then be set up to
provide additional amplification (+20dB). This is the preferred connection method.
•
Alternatively, the Remote Unit itself can provide microphone amplification. To set
this, open up the Remote Unit and locate the jumper labelled ‘MIC’ on the
daughterboard. Connect this jumper across the pins. The Local Unit’s ‘Line Out’
connection should then be wired to ‘Line In’ (blue) on your sound card.
If your microphone is already amplified, follow the second method but DO NOT install the
amplification jumper in the Remote Unit.
