The interface plugs into any standard PC 25 way D-type parallel port. Supported parallel port modes are: * * * Nibble mode Byte mode EPP mode depending on which mode the host PC can support. Connection to the development target is via a JTAG connector. Once connected, the development target can be accessed using the MS Windows drivers supplied with the standard ST20 toolset. 3/10 (R) ST20-JPI 2 2.1 Installation Hardware Installation - PC The ST20-JPI has six connections: Parallel port; Differential OS-Link, JTAG, TrigIn, TrigOut and Power supply. To install the hardware connecting to a PC, the following steps should be followed: * * * * * * Plug the 25-way D-type of the parallel port cable built into the interface, into the parallel port of the PC. Plug the target development system into the 20-way IDC connector using a 20 way IDC cable. Plug power supply cable into PSU socket of the interface. Plug the power supply into the mains socket. Switch on the PC. Switch on the power supply. The LEDs on the interface should illuminate once the software is running. For a description of the meaning of the LEDs, see the ST20 toolset documentation.

To install the hardware connecting to a B300, the following steps should be followed: * * * * * * Connect the B300 to the ST20-JPI using a Differential OS-Link cable supplied with the B300. Plug the target development system into the 20-way IDC connector using a 20 way IDC cable. Plug power supply cable into PSU socket of the interface. Plug the power supply into the mains socket. Switch on the B300. Switch on the power supply to the ST20-JPI. The LEDs on the interface should illuminate once the software is running. For a description of the meaning of the LEDs, see the ST20 toolset documentation. Switch on the Target power supply. * 2.3 Software Installation For installation of the DLL and VxD drivers, please refer to the ST20 Toolset software installation documentation. 5/10 (R) ST20-JPI 3 3.1 Connectors The ST20-JPI front panel LEDs SMB TrigOut SMB TrigIn 20 Pin IDC Header JTAG Connection 3.2 The ST20-JPI rear panel PSU Connector Differential OS-Link Parallel Port Connector 6/10 (R) ST20-JPI 3.3 Differential Link Connection The Differential OS-Link connector is used to connect the ST20-JPI to a B300 instead of a Parallel port.

The following table shows the pinout of the ST20-JPI and the pinout required for the target board: Pin Number Even Numbers 1 3 5 7 9 11 13 15 17 19 Host Connection GROUND Reserved TrigIn TrigOut Reserved TMS (Out) TCK (Out) TDO TDI notRST (Out) notTRST (Out) Target Connection GROUND Do Not Wire TrigOut TrigIn Do Not Wire TMS (In) TCK (In) TDI TDO notRST (In) notTRST (In) Table 3.2 JTAG connector pinout 7/10 (R) ST20-JPI 3.5 TrigIn/TrigOut SMB Coaxial Connectors The two coaxial SMB connectors to the left of the LEDs are used to connect the ST20-JPI to a Logic Analyser. They are used to signal between the Host, Target and Logical Analyser when an event occurs. If, for instance, an event occurs on the Target processor, the TrigOut signal is triggered which could start the Logic Analyser tracing an external event, so aiding software/ hardware debugging. TrigIn/Out GND 3.6 Power Supply Connector The ST20-JPI uses a 2.5mm power connector. The voltage range is 8-13V dc. +V GND 4 Recommended Target Circuitry To ensure correct connection to the target processor, the following circuit should be used: VCC ST20-JPI 10K ST20 TDO TDI TMS TCK notTRST TrigIn TrigOut notRST Board PowerOnReset Target Board 8/10 (R) ST20-JPI 5 Field Support SGS-THOMSON Microelectronics Limited products are supported worldwide through Sales Offices and authorized distributors. 6 Ordering information Description ST20-JPI Parallel Port to JTAG Interface (US) ST20-JPI Parallel Port to JTAG Interface (European) ST20-JPI Parallel Port to JTAG Interface (UK) Order Number ST20-JPI/110 ST20-JPI/220 ST20-JPI/UK Table 6.1 Ordering information 9/10 (R) ST20-JPI 10 Information furnished is believed to be accurate and reliable.
