4.3Operational Commands

Five operational commands recognized by the SCANTEAM 3700 are: <A> – resets the 3700

DC4 – disables bar code scanning DC2 – enables bar code scanning <1> – serial trigger

<Z> – saves current configuration in non–volatile memory.

Explanations, ASCII and hex characters for the operational commands follow.

Reset Command <A>
COMMAND	ASCII	Hex Characters
Reset	<A>	3C 41 3E

Sending the operational command <A> causes the 3700 to reset. After reset the 3700 will operate according to the last configuration saved in non–volatile memory. If a valid configuration cannot be retrieved from memory, the 3700 will operate according to the default configuration.

Disable Decoding Command DC4

COMMAND	ASCII	Hex Characters
Disable Decoding	DC4	14

This is a single character command. Sending the operational command DC4 will cause the 3700 to stop looking at bar code data.

Enable Decoding Command DC2

COMMAND	ASCII	Hex Characters
Enable Decoding	DC2	12

This is a single character command. Sending the operational command DC2 will allow the 3700 to decode according to its current configuration.

Note: DC4 and DC2 are ASCII control characters. With a terminal emulation program running on a PC, send a DC4 by holding down the CTRL key while pressing the “T” key. Send a DC2 by holding down the CTRL key while pressing the “R” key.
