input on the local Xstream, you would therefore cause current to flow into the
corresponding output at the far end unit. These can also be used for local control
and to monitor local status see section 10.5 has additional information on the use of
this port.

ZEPHYR CLASSIC VS. XSTREAM COMPARISON!
The original Zephyr has only four inputs and outputs numbered 0- 3 while the
Xstream has 8 inputs 0- 7. The four inputs and outputs of the Zephyr will
communicate with the first four inputs and outputs of the Xstream (i.e. 0- 3)

These pins are compatible with
the corresponding
input/outputs of the Zephyr.
NOTE: Pin 1 is connected directly to the +5 volt power supply. Failure to limit
current draw on this pin could cause hardware damage or system instability.
Parallel Outputs 0-7
Outputs are open collector to ground and can sink up to 125 mA of current each
(actually, any output can sink up to 400 mA, however the maximum combined
current should be kept below 1000 mA.
