Obtaining passcodes• For DCM-300 modems ordered before 28 November 2011, passcodes can be retrieved

from the Partners Store/CNH Partners Store. Go to the Upgrades tab and then select Retrieve Passcodes.

– You can search by serial number, part number, order number, or purchase order.

– The unlock code is automatically generated in the Retrieve Passcode section once a DCM-300 modem is purchased.

• For DCM-300 modems ordered after 28 November 2011, all kits that include passcodes for VRS corrections and the Connected Farm™ software are pre-installed by Trimble before the units are shipped.

General information• The cabling that connects the DCM-300 modem to a FM-1000™ integrated display /

FM-750™ display is the same for both VRS corrections and Connected Farm Office Sync.

• The GPS patch antenna (included) is recommended but not required for the modem unless you are using the Asset Tracking service.

• The modem has 3 different unlock codes that are stored on the modem itself, not on the display. They are:

– File transfer, VRS corrections, Internet, and Wi-Fi

– Ag Bus vehicle bus config (for Telematics)

– Cellular parameter modification (This unlock enables you to enter and edit SIM card settings if you need to activate the DCM-300G modem for a third-party cellular provider.)

Note – If the DCM-300 modem is not unlocked for File Transfer, VRS, Internet, and Wi-Fi, the modem will not connect to a AgGPS 262 receiver.

• The AgGPS 262 receiver must have version 2.0 firmware or higher and use the same setup option as an Ag3000 modem in the RTK Configuration settings.

• The FM-1000 / FM-750 display does not need to be unlocked for RTK if you are only using Connected Farm Office Sync service.

• The FM-1000 / FM-750 display must be unlocked to RTK level if you are using the modem for VRS corrections.

• The DCM-300 modem saves some settings internally and can be set up for VRS corrections through one display and later transferred for use with another display. The modem holds its configuration and transfers it to the second display on power up.

• Trimble does not offer temporary cellular activation for the DCM-300 modem in the USA (for example, as is the case with the AG3000 modem.



C WARNING – Damage to the USB hub can occur if the main connector c is connected after power d and USB e have already been connected. You must connect the torch main connector c before connecting the power and USB.

Receiver compatibilityThe DCM-300 modem is compatible with the AgGPS 262 receiver, the AG-372 GNSS receiver, the FM-1000 integrated display, and the FM-750 display.

The DCM-300 modem is not currently supported by other Trimble GPS receivers, including the EZ-Guide® 500 lightbar and the AgGPS 252 / 432 / 442 / 452 receivers.

The DCM-300 modem cannot be used with third-party GPS receivers.

Troubleshooting

Troubleshooting

Communication between the DCM-300 modem and an FM-1000/FM-750 display

If there is no communication between the modem and the display, try the following:

• Make sure that the display can “see” the DCM-300 modem from the Unlock screen three minutes after startup. If the DCM-300 option appears in the Unlock screen the display is communicating successfully with the DCM-300 modem.

• Make sure that the FM-1000 integrated display is connected to the modem using the supplied USB hub and that the green LED light on the USB Hub is solid.

Note – The FM-750 display does not require a USB hub but it is recommended.

• Make sure that the USB port on the FM-1000/FM-750 display is working correctly. To check this, insert a USB drive into the back of the display—if the display recognizes the USB drive or allows you to load firmware into the display the USB port is working correctly.

Note – The USB port will either work for everything or not work for anything.

• Check power connections to the DCM-300 modem. The power lead must be connected to a constant 12 V source and the ignition lead must be connected to a switched 12 V source for operation.

• Make sure that cable P/N 82033 (connecting the USB hub to the modem) has no faults or breaks.

If you still cannot establish communication between the modem and the display, try using a different DCM-300 modem.

Communication between the DCM-300 modem and an AgGPS 262 receiver

Make sure that the following is correct:

• The AgGPS 262 receiver has version 2.0 firmware or higher, is unlocked for RTK, and has been configured for communication to an AG3000 modem.

• Cable P/N 82133 from the DCM-300 modem is connected to port B on the AgGPS 262/ AG-372 receiver.

• Port B is configured for RTKLINK 38400 for both input and output.

• The constant power is connected to the machine battery and the ignition lead is connected to a switched 12 V source.

If the AgRemote display shows a message No AG3000 found, the receiver is not communicating with the modem. Check the following:

• Make sure that the DCM-300 modem is unlocked for VRS operation. If the modem is not unlocked for VRS operation, the receiver will not communicate with the modem.


Troubleshooting

• Check the cabling connection between the modem and port B of the receiver. If cable P/N 82133 is damaged, the receiver will not communicate with the modem.

• Check the power connections to the DCM-300 modem. The power lead must be connected to a constant 12 V source and the ignition lead must be connected to a switched 12 V source for operation.

If you still cannot establish communication between the modem and the receiver, try using a different DCM-300 modem.

Troubleshooting cellular communication • For the DCM-300G modem, it is recommended that you disable SIM PIN codes if you

are using more than one SIM card, or alternatively, set the same SIM PIN for all SIM cards.

• For the DCM-300C modem, it is recommended to check the Verizon coverage map for data and ensure that the first use of the modem is done in a native Verizon coverage area.
