Serial Ports 1 and 2 RS232/RS485/RS422 Connections
The evaluation board has two multiprotocol RS-232/RS422/RS485 ports for connection to the
PremierWave 2050 internal UARTs. Serial port 1 is a DB9 type connector labeled J6. Serial
port 2 is a DB9 type connector labeled J7. A null modem cable can be used to connect J6 and
J7 directly to a standard PC RS232 serial port.
The tables below list the RS232/RS422/RS485 signals and corresponding pins on the
evaluation board DB9 connectors. All signals at J6 and J7 are level-shifted by a multiprotocol
transceiver.
