Communications
The DEMO908GZ60 module provides a single serial communications port and a single CAN
communications port. The Enhanced SCI port supports both RS-232 and Local Interconnect
Network (LIN) protocols. An option jumper (COM_SEL) selects between the communications
protocol implemented. The CAN port utilizes a direct data connection to the MCU and pro-
vides a 3-pin header to connect off-board circuits.
RS -232 Communic ations
An RS-232 translator (U2) provides RS-232 signal level to TTL/CMOS logic level translation on
the COM port. Signals TXD and RXD are routed between the transceiver and the MCU.
These signals are also routed to connector J1. RS-232 communication signals input on J1
must be TTL/CMOS logic levels; no translation support is provided through this path. The
transceiver output may also be driven off-module if a suitable interface is used. As added de-
velopment support, hardware flow control signals RTS and CTS are available on the logic side
of U3. These signals are routed to vias located near the transceiver (U3). RTS has been bi-
ased properly to support 2-wire RS-232 communications.
Use of the J1 connector to input RS-232 signals requires disabling the on-board RS-232 trans-
ceiver to prevent signal corruption. Disabling the on-board transceiver is accomplished by re-
moving the COM_SEL jumper. Details on the COM_SEL jumper are shown in the table below.
The figure shows the jumper position to enable RS-232 communications.
