INSTALLATION GUIDE
Model 400 USB Flash Module
Description
The Model 400 USB Flash Module allows you to easily field update
firmware for panels that would otherwise require the use of a computer
and a Model 399 Programming Harness.
The Model 400 is equipped with a standard USB 2.0 compatible Type
A female connector for interface to a USB Drive, a 4-pin connector
between the Model 400 and the compatible panel, and an LED to
indicate panel update status.
Compatibility
Compatible with XT30/XT50 Series panels, XTLC, XTLplus, and the
CellCom-LTE-V.
Caution:
Do not connect a Model 400 to the CellComF-LTE-V if using 24 volt power.
Downloading the RU file to the USB Drive
To download a new firmware version RU file to the flash drive:
1. Connect a USB flash drive to your computer with a USB 2.0 compatible Type A female port.
2. Locate and download the panel’s firmware update RU file from DMP.com/Dealer_Direct and save it to the Root
directory of the flash drive.
3. When complete, disconnect the flash drive from your computer.
Note:
The Model 400 only supports flash drives using a FAT32 file system. If multiple RU files are saved to the flash
drive, the file with the most recent Date Modified will be used by the Model 400.
Updating the Firmware
The Model 400 connects to the compatible panel via the panel’s programming PROG header. Updating firmware does
not change current panel programming. To update the panel with a new firmware version:
XT30/XT50
1. Remove the yellow and green wires from keypad bus terminals 8
and 9.
2. Connect the USB flash drive containing the RU file to the Model
400 and connect the assembly to the panel’s Programming PROG
header. The LED on the Model 400 will flash and then display
steady green.
3. Place a jumper across the Reset header.
4. Place a jumper across the Load header.
5. Remove the jumper from the Reset header.
6. Press and release the load button on the Model 400 to initiate
the firmware update. The LED on the Model 400 will flash slowly.
If the LED displays fast flashes it means the firmware update was
unsuccessful. The update will take approximately 4.5 minutes
and when complete the LED on the Model 400 will display steady
green.
7. Replace the jumper across the Reset header then remove the USB
flash drive and Model 400 assembly.
8. Remove the jumper from the Load header.
9. Remove the jumper from the Reset header.
10. Reconnect the yellow and green wires to terminals 8 and 9.
In the event the Model 400 USB Flash Module is inadvertently removed from the panel before
the update finishes, repeat steps 1 through 10.
