Click on the Send ENQ button:
a.
If you get a Loop back detected message the interface cable and connectors from the
ARTOS interface board are all OK. Following are some possible problems and or further
testing:
i.
Reconnect the RX and TX wires to the Imaje Industrial Interface board but
reversing the connections from what they were before.
ii.
The Imaje Industrial interface could be the problem, if it works find out why and
fix. Wires or pins in connectors are mixed somewhere.
iii.
Check the Jumpers that are suppose to be installed, see wiring diagrams for either
S4/S8 or 9040 wiring, there is a difference
iv.
Call Imaje if all the above does not find the problem, you need to have the Imaje
industrial interface board checked or replaced.
b.
If you still get a timeout then you have only confirmed that there is a problem on the
ARTOS side. First isolate and fix the ARTOS problem first as follows:
i.
At the ARTOS ink jet interface board disconnect the TX and RX lines from the
control to the ARTOS ink jet interface board.
ii.
Short these disconnected lines together.
iii.
Click on the Send ENQ button:
1.
If you still get a timeout then check the wiring back to the ARTOS
controller board, if this is correct you may have to replace the controller
board, but first check the other wiring to the board on the ARTOS
controls side and especially the power supply wiring. If all is correct
replace the board.
2.
If you get a Loop back detected message the ARTOS controller RS232
port and wiring to the ink jet interface board is OK and the problem is
elsewhere.
a.
Reconnect the wires.
b.
Pull the DB25 connector.
c.
Jumper pins 2 and 3 on the ARTOS ink jet interface board DB25
connector
d.
Click Send ENQ:
i.
If you get loop back detected the problem is in the Cable
and connectors going to the Imaje. You will need to ring
out the cable from end to end.
ii.
If you do not get a loop back detected the problem is
probably the Board. Replace it and try again.
Once you fix the ARTOS problem reconnect the RX and TX wires, removed in step #1,
to the Imaje Industrial interface. (Basically go back to step #3 ) Try the Send ENQ again
if you still get a Timeout with no response there is a problem with the Imaje industrial
interface. Look at possibilities in Step #3-a. Just double check the cable wiring and
jumpers installed on that card before contacting Imaje.
