Error indications
“NO ERRORS”
No errors detected.
“MEM-ERROR”
Memory error detected.
“CAL-ERROR”
Validation of calibration problem detected.
“NO-COMM”
Not receiving communication from MASTER display.
“SIG-HIGH”
Sensor signal voltage too high (greater than 4.8V).
“SIG-LOW”
Sensor signal voltage too low (less than 0.4V).
“CAL NOT FINISHED” Calibration was started but not completed.
“TYPE-BAD”
Unit type cannot be determined (not MASTER, REMOTE, or CAL INCOMPLETE).
3.7. Configure the communication method
A MASTER display can communicate to other displays that are configured as remotes via CAN or 1-wire.
The 1-wire communication method is the default method and will work with ITL40 and ITL displays.
The CAN communication method is new for the ITL40 displays and is a more robust communication method. This
method requires two wires (CAN high, CAN low) and approved J1939 CAN wiring and connectors. There should be
two (2) 120 ohm terminating resistors located at the ends of the CAN bus (see section 6.3.5).
3.7.1.
Configuring a display as a Master with 1-wire communications
Enter the password
LRLL LLLR
to set the communication method to 1-wire. If the display was not previously a
MASTER display, calibrate the display
(see section 3.3).
3.7.2.
Configuring a display as a Remote with 1-wire communications
Enter the password
LRLL LLLR
to set the communication method to 1-wire. If the display is a MASTER display,
enter the password
LRLR LRLR
to turn the display into a REMOTE.
3.7.3.
Configuring a display as a Master with CAN communications
Enter the password
LRLL LLRL
to set the communication method to CAN. If the display was not previously a
MASTER display, calibrate the display
(see section 3.3).
Choose the CAN identification address to use (either address 1, 2, 3, 4, or PCM) and enter the appropriate
password to set the address (
LRRR LLLL
address 1
, LRRR LLLR
address 2,
LRRR LRRR
address 3,
LRRR RLLR
address 4,
LRRR LRLR
address PCM). All REMOTE displays that are to mimic this Master display
must have their addresses matching the MASTER
’s.
3.7.4.
Configuring a display as a Remote with CAN communications
Choose the CAN identification address to use (either address 1, 2, 3, 4, or PCM) and enter the appropriate
password to set the address (
LRRR LLRL
address 1
, LRRR LLRR
address 2,
LRRR LRRL
address 3,
