Commands may be sent to the Smarteye Electronic Assembly via command points. A command point is configured as a 2-character string point at address S1.
The first character of the command point is the command code. The second character specifies the reader number for certain commands.
The following commands are directed at the SEA and do not require a reader ID.
|
Code |
Command Description |
|
R |
Restart. Initialize all readers on-line. |
|
B |
Box poll. Request message from any reader in the SEA. |
|
A |
Ack. Acknowledge the previous transmission. |
|
N |
Nak. Negatively acknowledge the previous transmission. |
The communication enabler uses these commands to interact with the SEA. Generally, they should not be used interactively.
The following commands are directed at specific readers and do require a reader ID.
