Status String Format

Following execution of each command, PowerWave sends a status string

back to the computer if Return of Status is enabled. This string consists of

5 ASCII characters -- RS, S3, S2, S1, and ETX:

⇒

A record separator that marks the beginning of the status

string.

⇒

A hexadecimal digit, 0 through F, where the bits mean:

8 - stepper motor busy

4 - printer busy

2 -

1 -

⇒

A single digit, used as a reader fault or error code number.

ERROR CODES

Error code numbers indicate the following:

0 - no fault or error

3 - analog channel out of range

6 - printer busy for more than 3 seconds

7 - checksum byte of downloaded file does not

match.

8 - WCF error detected during plate read.

⇒

Byte S1 will always be zero.

⇒

ETX
