POWER UP CLEAR (Command 'A')

Purpose: This command has no internal module affect. It is used as a simple method to verify proper communications to the 9816 scanner.

Command	“A”
	‘A’ is the command letter
Response	“A”
	‘A’ is the acknowledge letter

Description: The Ethernet Model 9816 does not return a ‘Power-Up Clear Expected’ error (as did early 901x modules without Ethernet interface). This is due to the reset notification mechanisms that are part of the TCP/IP protocol. It is generally used as a simple ‘NOP’ mechanism to verify proper communications with a module.

Example:

●Send TCP/IP command to Model 9816 module (via its open socket) to acknowledge module power on:

"A"

Read following response:

"A"
