If the device is sending data faster than the software can process it, the "tail" of one packet might be cut off or merged with the "head" of another. This creates a malformed string that the system cannot parse. 4. Power Supply Issues
Many fingerprint and iris scanners use 0x96 as a "Template Data" or "Status Acknowledgement" packet.
Visit the manufacturer’s website for the specific "SDK Driver." the data packet with type-0x96- returned was misformatted
When the system says the packet is it means the software received the data, but the structure (the header, the payload size, or the checksum) didn't match the expected blueprint. Common Causes of Misformatted Packets 1. Driver Mismatch
The most frequent culprit is a version mismatch between the hardware’s firmware and the computer’s driver. If the hardware sends a 64-bit data string but the driver is expecting a legacy 32-bit format, the packet will appear "misformatted." 2. Electrical Noise and Interference If the device is sending data faster than
Some specialized security hardware uses this packet type during the initial decryption phase.
Check your device manager. If you recently updated Windows or your control software, the new driver might be interpreting the 0x96 packet differently. Power Supply Issues Many fingerprint and iris scanners
PLCs (Programmable Logic Controllers) sometimes use this hex code for heartbeat signals or specific sensor readouts.
In hexadecimal notation, 0x96 (decimal 150) often serves as a functional command or response code within specific SDKs (Software Development Kits). While not a universal TCP/IP standard, it is most commonly associated with:
