The CPT-DAJ is a Communications Peripheral card within the DA Series Range with an isolated JTAG and Serial Communications Interface (SCI)/UART. It provides an isolated USB interface for a Texas Instruments based microcontroller (MCU), as found on CPT’s DA Series Control Cards. The JTAG Emulator within the CPT-DAJ is the XDS100 V2. The card uses the same interfacing circuitry and EEPROM as Texas Instruments' own controlCARD series.

The card requires a powered USB connection for the isolated USB side to operate.

The CPT-DAJ card mounts over the DA controller card using the DA Series 14-way JTAG Interface for communication with the DA Series Control Card.

In addition the CPT-DAJ contains an LVTTL UART interface compatible with the DA Series cards (CPT-COM-U equivalent).
