5-4 | 3050 AM Moisture Analyzer
Echo (A)
Echo implements a loop back function to test the integrity of the serial
communication. Any text transmitted by the master is returned.
Example:
Master: >99ABCDEFG4E[CR]
Slave: AABCDEFG1D[CR]
Bad Command (B)
This command is not recognized by the slave. It will therefore result in a
type 01 failure response.
Master: >99BB4[CR]
Slave: N01[CR]
Acknowledge (C )
Requests a simple acknowledge from the slave. Useful to determine if
there is a device at that node address.
Master: >99CB5[CR]
Slave: A[CR]
Read Data (F)
The data field of this frame contains the handle for a system variable. See
Figures 5-7a and 5-7b for a list of defined handles for system variables.
Example:
Master: >34F0512[CR]
Slave: A1234540[CR]
