Symptom: HAAS machine tool connects over serial, but delivers no data.
The MachineMetrics Haas serial Adapter may report an alarm W0143 Setting 143 may not be enabled.
When connected via Telnet or terminal emulator, the control responds to Q100<enter> with a blank line and a new prompt:
(Note that the Haas doesn't echo input - the only reason you see the 'Q100' here is because PuTTY is set to echo keyboard input.)
Cause: HAAS controls will not answer to Q-codes unless the "Serial Data Collection" feature is available in the control AND the feature is enabled via Setting 143. The feature can be assumed available in all units produced after 2001, when it became standard. Haas vintage 2001 and older, check if Setting 143 is present.
HAAS Resource Center - Data Collection Using the RS-232 Port
Solution:
Make sure you have a working serial connection: After connecting RS-232 serial server, match the serial setting on serial server with setting on machine.
Turn on setting 143 by:
1) Press "SETTING" hardkey
2) Search for or scroll to #143
3) Turn setting on
4) Press ENTER/WRITE Hardkey
