AeroComm Corporation AC4490 Benutzerhandbuch

The AC4490 has a simple interface that allows OEM Host communications with the transceiver.  The table below
shows the connector pin numbers and associated functions.  The I/O direction is with respect to the transceiver.  All
outputs are 3.3VDC levels and inputs are 5VDC TTL (with the exception of AC4490-1x1 and AC4490-1000 transceivers
which have 3.3V inputs).  All inputs are weakly pulled High and may be left floating during normal operation (with the
exceptions listed for the AC4490-1x1).
