UART
EXAR…………………………… XR16C654
RS422/RS485 PORTS
Channel Configuration……..…. Eight independent, non-isolated
EIA/TIA-422B serial ports with a
common signal return connection.

even, or no parity.
Stop Bits………………………… Software Programmable 1, 1-1/2,
or 2 bits.
Data Register Buffers…………. The data registers are double
buffered (16C450 mode), or 64-
byte FIFO buffered (FIFO mode).

Termination Resistors are
installed in sockets on the module
and may be removed if required
(see Drawing 4501-715 for
location). For an RS422 network
install a terminating resistor at the
end of the network only. For an
RS422/RS485 network,
transmitting and receiving
channels may have terminating
resistors (RT) at both ends of the
network (see interface Drawing
4501-714).
