Auxiliary Interface - RS232
The auxiliary serial interface is used exclusively for RS232 point-to-point
connections. It is also used for configuring the DS1100.
The parameters relative to the auxiliary interface (baud rate, data bits, etc.) can be
defined using the
WinHost
utility program or "Host Mode Programming", installed from
the CD-ROM.
