1.3 RS-232C Terminal Interface
This connection provides an interface from the Vosponder to a computer. The
connection is made using a 9-pin female to 9-pin female null modem cable, as
shown in Figure 1-3.
This allows a user to configure various operational parameters, upload the
voice image file, view existing settings, and view incoming DTMF tones and
SDI-12 commands. The terminal interface is time-out protected, which means
that it will return the Vosponder to its runtime mode after 60 seconds of
inactivity on the terminal keyboard. This is done to prevent inadvertent system
lock-ups. A schematic of the connector can be found in Appendix B, Figure
B-3.
