Appendix B – Serial Protocol

The data glove is connected to the RS-232 port of the computer. The 5DT Data
Glove Ultra Wireless Kit is a transmit-only device, as it does not respond to any
commands sent to it.

The 5DT Data Glove Ultra has the following serial settings:

•

115200 bits per second

•

8 data bits, 1 stop bit, no parity

•

Hardware

handshaking:

none

The glove data arrives in packets. If two gloves’ data is present on the data
stream, then the packets will alternate from one glove then the other. It is
possible to distinguish the two by identifying the glove type from the type byte.

The data packet sent by the glove is structured as follows:

Byte No. Byte
