The diagram above shows the basic setup for the system. Data unit 1
and 2 communicate to each other through their RS-232 ports that are
connected to the transceivers. Each Data Unit must provide +5V power
and ground to the transceivers and well and the control and data signals.
Below is the connector pin out for the transceivers.
15 Pin Connector
Pin 1............. gnd Pin 10.....RXen (receive enable)
Pin 2............. Rx (receive data) Pin 12..........TX (transmit data)
Pin 5............. +5V Pin 14......... Rf signal level
Pin 6............ gnd
Pin 7............ Txen (transmit enable)
NOTES:
1) To Transmit: set Rxen low and let Txen float
2) To Receive: set Txen low and let Rxen float
3) TX and RX are TTL level logic, use a level converter to connect to
the RS-232 port of a computer.
