MDS Orbit MCR-4G Technical Manual
MDS 05-6628A01, Rev. B
WiFi Antenna
—Antenna connection for 2400 MHz WiFi service. The connector appears similar to the cel-
lular connectors discussed above, but is a
Reverse-SMA
type. It contains a pin that matches with an SMA-F
connector. The GE MDS part number for this antenna is 97-4278A48.
SIM Port
—This port accepts a mini SIM card (2FF type) for 4G cell operation. The unit’s cellular interface
will not function without a valid SIM card installed. The customer is responsible for obtaining a provisioned
SIM card for the appropriate service plan from their cellular provider.
CAUTION: Do not insert the SIM card when the unit is powered on.
Card Insertion: The SIM card only inserts one way; do not force it. It should be oriented with the printed
label facing up, and the cut-off corner on the left side. This side is inserted first. A small instrument, such
as a flathead screwdriver, may be helpful to
gently
push the SIM all the way in until it locks.
Information on determining the cell module’s IMSI/IMEI (typically required for provisioning) is provided
on

LED Status Indicators
—The LEDs on the unit provide visual indications of the status of the device as fol-
lows:
