» To confirm that power is present in the EchoPoint Reader:

1. Observe the indicators and the seven-segment display on the

LED display panel. The power indicator should be illuminated

whenever power is present.

a. During the initial power-on sequence, the EchoPoint

Reader displays its identification number (ID) in the

LED display as a sequence of five digits.

EchoPoint Reader ID number 1234 displays

the numbers 0, then 1, then 2, then 3, and then

4 in sequence during the initialization process.

b. After the ID display, two indicators flash at different

rates. One is the center bar of the segmented display

and the other is a small indicator within the segmented

display. If the indicators fail to flash, the EchoPoint

Reader is non-operational.

2. If at any time you are not sure that the EchoPoint Reader

is operating properly, reset the reader by disconnecting

and then reconnecting the power source.

After resetting the EchoPoint Reader SR-640-101, it

should repeat the power-on sequence described above.

The EchoPoint Reader is now ready for you to verify

communication functions.

Note: The EchoPoint Reader SR-640-101 has a watchdog

sensor that automatically resets the reader if power

fluctuations or other interruptions occur that might

affect the reader’s performance.
