RS-232
An RS-232 translator provides RS-232 to TTL/CMOS logic level translation on the COM
connector. The COM connector is a 9-pin Dsub, right-angle connector. A ferrite bead on
shield ground provides conducted immunity protection. Communication signals TXD1 and
RXD1 are routed from the transceiver to the MCU. Hardware flow control signals RTS and
CTS are available on the logic side of the transceiver. These signals are routed to vias located
near the transceiver. RTS has been biased properly to support 2-wire RS-232
communications.

COM Connector
A standard 9-pin Dsub connector provides external connections for the SCI0 port. The Dsub
shell is connected to board ground through a ferrite bead. The ferrite bead provides noise
isolation on the RS-232 connection. The figure below details the DB9 connector.

Female DB9 connector that interfaces to the MCU internal SCI0 serial
port via the RS232 transceiver. Flow control is provided at test points on
the board.
Pins 1, 4, and 6 are connected together.
COM_SEL
The COM_SEL option header connects the MCU SCI port to either the SCI PHY or the USB-
BDM connection.
