CPT-DFJ - Isolated JTAG/UART USB

CPT-DFJ

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

The CPT-DFJ card mounts within the DF Series stack and uses the DF Series 10-way JTAG Interface for communication with the DF Series Control Card.

The optional CPT-DFJ-DA provides compatibility with the standard 14-way JTAG interface, as used on the DA Series cards. This 14-way IDC connector interface is standard across a large range of JTAG interface cards. In addition the CPT-DFJ-DA contains an LVTTL UART interface compatible with the DA Series cards (CPT-COM-U equivalent). CPT recommends use of the CPT-DAJ as the preferred companion for the DA Series cards.

DF Series Peripheral Cards are available with alternative communications interfaces. The currently available cards in this range are the CPT-DFC1, CPT-DFC4 and CPT-DFJ.
