Fig. 2-4 The pin assignment of serial interface
Note: (1) “Source” denotes the source that signal come from;
(2) Logical signal level is EIA.
The baud rate and data structure in serial interface mode is 9600bps, 8-bit
data bits, no parity bit and 1 stop bit. The serial interface of SP-RME5 can be
connected to standard RS-232C interface. When it is connected to IBM PC or its
compatible machine, connection can accord to Fig.2-5.
