II.3.3 RS 232 Ports
There are two RS232 ports for use as auxiliary data ports. These ports allow the
transmission and reception of data along with encoded audio. Port A is always
ready. Port B is only available if the ProntoNet is configured as a DUAL Codec,
therefore able to operate two totally independent communication channels. Note
that these sockets are RJ45 connections, as opposed to the typical 9-pin subD
connections. To make the conversion between RJ45 and RS232 there are
modular connectors available that should be wired as follows:
S-Cluster

The ports are always set to 8 DATA bits, NO parity, 1 START bit and 1 STOP bit.
The bit rate can be adjusted to between 300 and 9600 bps via software.
The ProntoNet acts as a DCE device, therefore the connection to each of the
RS232 ports is wired in the following way:
ProntoNet – Pin 7 connector RJ45.........................Pin 2 PC
ProntoNet – Pin 2 connector RJ45.........................Pin 3 PC
ProntoNet – Pin 3,6 connector RJ45......................Pin 5 PC
The ProntoNet ignores hardware handshaking signals.
