dISP (Display) Setup Option 

 

In dISP setup, the parameters to be displayed are selected.  Only parameters selected to be 

transmitted by the Configuration Software can be displayed. 

 

Here is an example of setting the parameter to be displayed on the upper display: 

 

1.

 

Press the SYS key until “MOd” is displayed. 

2.

 

Press the 

↓

 key until “dISP” is on the top display.  Then press the ENT key. 

3.

 

Press the 

↓

 key until desired parameter name is displayed.   See Tables 3 and 4.  Then 

press the ENT key. 

4.

 

Press SYS to return to RUN mode. 

 
 

CONF (Configure) Setup Option 

 

CONF setup appears at the end of the setup list on the lower display.  To enter CONF, press 

the SYS key until “MOd” appears on the upper display, press the 

↓

 key until “CONF” 

appears on the bottom display, and then press the ENT key.  CONF is for global dashCAN 

setup. 

 

‹

 

LEdS 

 

The display intensity is programmable.  Press the ENT key when “LEdS” appears on the 

lower display, press the 

↑

 or 

↓

 keys until the display intensity is suitable, press ENT, and 

press SYS to return to RUN mode. 

 

‹

 

LOCK 

 

“LOCK” locks the MOd, RATE, dISP, and LEdS setup.  This stops unauthorized 

modification of the display.  Refer to Appendix E for more information.
