Dip Switch Settings; Mmi Indicator Lights; Other Hardware Considerations - KEP MMI-7 Series Installation Instruction

Case 3: Ethernet Connections: Units equipped with the Ethernet port can be connected via Ethernet to a
Master and Slaves using standard 10T Ethernet cables. Slave to Master, connect the Ethernet ports with a
standard (Category 5) Ethernet 10T crossover cable (RJ-45 to RJ45). Alternatively, use standard cables
with routing passing through Hubs and Servers as needed.

5.0 Dip Switch Settings

All dipswitches should normally be in the OFF (down) position. Dipswitches 1 and 2 are used to perform
testing and recovery functions. Dip Switch 3 and 4 are not used and should be left in the off position.

Note: It is normally not necessary to change dipswitches to put the MMI into programming (RDS) mode.

6.0 MMI Indicator Lights

PWR – Indicates if power has been applied to the unit. If this indicator fails to light, check power,
check polarity of wiring and check fusing. If all conditions are correct, contact the factory for help.
CPU – Indicates that the CPU is operating properly. If this indicator fails to light, please contact
factory.
COM – Lights when a serial transmission is sent or received. This indicator appears to flicker
when trying to establish communications.

7.0 Other Hardware Considerations

7.1 TOUCHSCREEN CALIBRATION
Normally the touchscreen is calibrated at the factory for proper functionality. If the touchscreen cannot be
calibrated, please contact the factory for assistance.
Run the EasyManager Utility to get to the Touch screen calibration (Touch Adjust) mode.
Click Jump to Touch Adjust to put the unit in this mode. This is used to calibrate the touch screen.
On the screen of the MMI unit:
1. Touch the crosshairs as displayed in sequence on the screen.
2. Touch anywhere outside to the rectangles to move the crosshairs to that location.
3. Touch inside the left rectangle to repeat the calibration process.
4. Touch inside the right rectangle to accept and end the calibration procedure.
5. Touch the screen again to jump to application mode.
