Appendix 1 Unpacking and Inspection
Inspect the outside of the shipping carton for damage. If damage is detected, contact
the carrier immediately. Remove the instrument from the shipping container. Be
careful not to discard any parts or supplies. Confirm that all items on the packing list
are present. Inspect all assemblies and components for damage. Save the original
packing carton. Carriers typically require proof of damage due to mishandling.

Status leds
There are 2 status leds located on IOEM and REM devices. The leds are located left
of the DC power connector location at A on IOEM and REM devices
The PWR status LED is illuminated solid green when 12v power is applied. The COM
status LED has 3 states as described below:
1.
OK (RS485 communications active)
A. Short (100mS) flash every second. This is the normal and most common
state.
2.
Communication error
A. Fast blinking (on 200mS/off 200mS)
3.
Bootloader, when firmware is being uploaded
A. Slow blinking (on 500mS/off 500mS)
