How to Obtain Your DMA Card DNA ID

DNA ID is the unique identifier of a specific DMA card. It is used to bind personalized firmware to that device. Read it on the secondary PC before writing the BIN file.

What you need

1. 1
   A supported 35T, 75T, or 100T DMA card.
2. 2
   A secondary PC running Windows 10 or 11 with a free USB 3.0 port.
3. 3
   A known-good USB 3.0 data cable connected directly, without a passive hub.
4. 4
   The fully extracted DATA DISTRICT DMA archive.

Connect the card

1. 1
   If the card has a physical power switch, set it to ON.
2. 2
   Shut the main PC down and install the card in a free PCIe slot.
3. 3
   Connect the Type-C cable to the service JTAG / CFG / Update port, not the DATA port.
4. 4
   Connect the other end directly to a USB 3.0 / 3.1 / 3.2 port on the secondary PC, then boot both computers fully.

Read the DNA ID

1. 1
   Run JtagDrivers.exe from the archive as administrator and complete the installation.
2. 2
   Open DATA DISTRICT DMA\DNA_ID.
3. 3
   Run the script that exactly matches the card FPGA: CH347-35T.bat, CH347-75T.bat, or CH347-100T.bat. Use 35T.bat, 75T.bat, or 100T.bat only as the corresponding fallback.
4. 4
   Copy both output lines in full: the binary and hexadecimal DNA values.
5. 5
   Send the DNA ID, card model, and order number to @SpiralDD.

Troubleshooting

1. 1
   If the driver fails, fully extract the archive, reconnect the JTAG cable, and rerun the installer as administrator.
2. 2
   If the card is not detected, try another USB 3.0 port, PCIe slot, and known-good USB 3.0 data cable.
3. 3
   If the primary script fails, use the fallback script for the same FPGA family only.
4. 4
   If the script closes immediately, verify that the archive was fully extracted and all files remain together.
