5.9.2 Radio RX Timeout

When the scanner is used in a standalone layout (point-to-point or with multiple

readers) it can be configured to receive “asynchronous” messages from the host at

any time.

There are two modes which can enable the scanner to receive messages from the

host:

1) Enable “2 way” Communication Protocol – After the transmission of each

barcode, the scanner waits for an acknowledgement from the host

. A message can

be sent by the host accompanying this acknowledgement, or in place of it, to display

something on the screen or execute a command (such as sound a beep sequence,

turn an LED on or off, etc.). If no acknowledgement or message is received from the

host within a programmable timeout duration, the radio will be switched off and an

“error transmission” beep will be sounded.

2) Independent of the Selected Protocol – The scanner can be configured to keep

the radio receiver “awake” for a defined period of time following each transmission.

Any message coming from the host1 before expiration of the timeout is accepted. The

parameter “Radio RX Timeout” is used for specifying how long the scanner have to

wait for a message after receiving each code transmission.

In this mode, the radio can also be “awakened” by pressing the trigger.

The scanner can receive a message only if it is linked to the Base (i.e. the scanner has

been joined to the Base and has had at last one “valid” transmission after the last

power-on). Setting the “Radio RX timeout” value to “00” specifies that the radio

never goes into sleep mode (always awake the scanner can receive a message at

any time). Choosing this setting will, of course, consume battery life more quickly.

See Section 6.2 for Host to Scanner message formatting.

5.9.3 Power-Off Timeout

If this command is enabled, after the desired timeout in hours, the PowerScan

™

batteries are disconnected and all power consumption ceases. To restore power,

press the trigger once. The reader will now be ready to read codes.

Power-off does not affect configuration parameters.
