Description
Value
Number of serial ports
2
Applications serial port
(In CE Mark certified systems, the Link
Controller must be used only in
communication fault tolerant systems. That is,
communication retries must be tolerated.)
Signals are galvanically isolated from logic common.
This port may be interfaced via the Personality module’s J2 male DB9
connector (refer to Table 2-2 or Table 2-3)
OR
via the Base unit terminal block (refer to Figure 2-2).
(1C31169G01) RS-232 signal levels: Note that standard IBM PC/AT
COM1 port pin assignments are present at the J2 DB9 connector
OR
(1C31169G02) RS-485/RS-422 signal levels: four wire link,
RS-485/RS-422 transmitter/receiver. Resistor terminations are user
selectable.
Applications serial port baud rate
300, 600, 1200, 2400, 4800, 9600, or 19200
