Page 3: Introduction
RS232 Ethernet (10 BASE-T) The bdiAccess library can be used to access the BDI2000 functions. With this library, a program run- ning on a Windows/Linux/Unix host can take advantage of the JTAG interface of an MIPS32 based target processor and execute the following tasks: •... -
Page 4: Installation
Installation Manual 2 Installation 2.1 Connecting the BDI2000 to Target The cables to the target system are designed for the IDT RC32300 Development Boards (optional available: Part# 90070) and for EJTAG 2.5 compatible boards (enclosed). In case where the target system has the same connector layout, the cable (14 pin or 24 pin) can be directly connected. - Page 5 3.0 – 5.0V with Rev. A/B : This input to the BDI2000 is used to detect if the target is powered up. If there is a current limiting resistor between this pin and the target Vdd, it should be 100 Ohm or less.

Page 6: Changing Target Processor Type
2.1.1 Changing Target Processor Type Before you can use the BDI2000 with an other target processor type (e.g. ARM <--> MIPS), a new setup has to be done (see chapter 2.5). During this process the target cable must be disconnected from the target system. -

2.2 Connecting the BDI2000 to Power Supply 2.2.1 External Power Supply The BDI2000 needs to be supplied with 5 Volts (max. 1A) via the BDI OPTION connector (Rev. A) or via POWER connector (Rev. B/C). The available power supply from Abatron (option) or the en- closed power cable can be directly connected. -

The communication cable between BDI and Host is a serial cable (RXD / TXD are crossed). There is the same connector pinout for the BDI and for the Host side (Refer to Figure below). -
Page 11: Ethernet Communication
Installation Manual 2.4.2 Ethernet communication The BDI2000 has a built-in 10 BASE-T Ethernet interface (see figure below). Connect an UTP (Un- shilded Twisted Pair) cable to the BD2000. For thin Ethernet coaxial networks you can connect a commercially available media converter (BNC-->10 BASE-T) between your network and the BDI2000. -
