VOICECRAFTERTM COMPUTER CONTROL MANUAL

INTRODUCTION

This manual documents the control commands for the Voicecrafter 3000 Series

products. This manual is designed to be used by those trying to control or write
remote control programs for the Voicecrafter.

SERIAL INTERFACE AND DATA COMMUNICATION PERAMETERS

Computer control can be accomplished through either of the RS232 ports on the

rear of the Voicecrafter. The upper DB9 female port is DTE format, and utilizes a
standard RS232 serial cable. The Lower DB9 male port is DCE format, and
operates as a null-modem port, it utilizes a serial cable with pin 2 and pin 3
‘swapped’. If the device controlling the Voicecrafter does not control the RTS
and CTS lines, then pin 7 and pin 8 must be tied together.

The upper DB9 female port operates at 9600 baud rate and cannot be changed.

The lower DB9 male port supports 300, 1200, 9600, 19200, and 38400 baud
rates. Baud rates are changed via the upper DB9 female port using SC-300 User
Control Interface software (NETWORK screen). Also, the DB9 male baud rate
can be changed by sending a ‘control J’ command through the upper DB9 female
port.

TYPES OF CONTROL

The Voicecrafter supports the use of terminal emulation commands (ASCII

Characters), dummy terminal emulation (‘s’ Commands) and advanced control
(‘t’ Commands).

ASCII CHARACTERS

All of the ASCII characters represent the same functions that are used by the

SC-300 software, and by the HHT (Hand-Held Terminal - discontinued as of
1/1/99). Most ASCII commands require the use of the F2 or F3 commands to
change values (See Voicecrafter 3000 Series Operation Manual for more details)
The following table defines the ASCII characters used:

s-Commands

The ‘s’ commands (used by the UC-300 User Control Console) allows limited

control of functions without making any permanent changes to the Voicecrafter
configuration settings. Each s-Command consists of a start byte (lower case 's')
followed by two command bytes (also lower case letters), but not followed by a
carriage return. Each of the s-Commands will generate a response from the
Voicecrafter. The response packet consists of two ASCII characters.
