DynaFamily Command Matrix

Every MMS command is documented once in this reference. This matrix shows which commands each DynaFamily reader supports, so you can confirm availability before building against a device. A command marked — is not available on that device's current firmware; some commands depend on a hardware option (noted below the table).

Notes on device-specific commands

• PIN / banking (Request PIN) require a PIN-entry device — PED only.

• Bluetooth LE commands (Terminate Connection, Erase Bonds) require a BLE radio — DynaFlex II Go only among these; corded devices omit them.

• Full-display UI commands (Display Message, Show Image / QR / Bitmap, Flexible UI Pages, Request Cardholder Signature) require the full touch display — DynaFlex II PED only.

• Read Barcode requires the barcode-reader (BCR) hardware option.

• Establish Ephemeral KBPK is a provisioning/manufacturing command — confirm whether it should be publicly listed or kept to an internal space.
