DIL/NetPC DNP/1486-3V: Parts and Components

A DIL/NetPC DNP/1486-3V is based on a 8-level multilayer printed circuit board (PCB). On this PCB with the size of only 82mm * 28mm are assembled numerous different components with SMD technology. Thereby both sides of the PCB are used for mounting the SMD components. The following figure shows the position of the most important components on the upper side of the DNP/1486-3V PCB.

DIL/NetPC Parts 1

The central component on the printed circuit board upper side forms the 32-bits low power AMD SC410 microprocessor. Close to the SC410 is found a 2 Mbyte FLASH memory chip with the entire firmware (BIOS, operating system, TCP/IP stack and application programs) as well as a 10 Mbps 10BASE-T Ethernet LAN controller with embedded buffer memory. Furthermore there are the 2-pin jumper JP1 and the 10-pin connector J2 available.

DIL/NetPC Parts 2

The jumper JP1 activates or deactivates the REMOTE CONSOLE MODE (RCM) function of the DIL/NetPC DNP/1486-3V. In this mode a user can operate the DIL/NetPC with a external PC and a terminal emulation program (for example Microsoft Windows HyperTerminal). The terminal program will be the "remote console" for the DIL/NetPC. If the RCM activated the console output, including the boot messages, are given out to the DIL/NetPC COM1 port. Console inputs goes the same way to COM1.

DNP/1486-3V Jumpers and Connectors
Name Function
JP1 Jumper. REMOTE CONSOLE MODE RCM) ON / OFF.
J1 Connector. 64-pin DIL Pinout.
J2 Connector. JTAG Interface for Factory- Test and Setup.

If the REMOTE CONSOLE MODE is activ (jumperposition JP1 closed = RCM activ), the DIL/NetPC is given out all boot messages from the BIOS and the operating system to the COM1 port. It is not examined, whether a PC with a terminal emulation program is connected to this port. Thereby is the COM1 port only for test and diagnostic suitable. The REMOTE CONSOLE MODE should be used only in the development stage. After that the jumper can be pulled (jumperposition JP1 open for "RCM not activ"). The REMOTE CONSOLE MODE is then not activ. In this condition no console I/O goes over the DIL/NetPC COM1 port. This port is then free for use by a application software.

Function of Jumper JP1 (REMOTE CONSOLE MODE)
JP1 Function
Jumperposition closed (Default Factory Setup) REMOTE CONSOLE MODE ON (activ)
Jumperposition open REMOTE CONSOLE MODE OFF (not activ)

It is to be considered, that the DIL/NetPC DNP/1486-3V examines the jumper JP1 only in the boot phase. Thus you should change these jumper only in the power off condition.

The connector J1 is formed through the 64-pin JEDEC DIL (dual-in-line) pinout. Please note, that the Pin 1 is marked for the DIL pinout on the upper side of the DIL/NetPC DNP/1486-3V printed circuit board. The connector J2 serves exclusively for the production and factory setup of the DIL/NetPC DNP/1486-3V. The pinout and function of this JTAG interface can change any time without announcement. If you need this pinout please contact the DIL/NetPC product support. Connector J2 is joined directly with the JTAG interface of the AMD SC410 microprocessor. In the factory setup we use this connector for programming the first boot loader to the DIL/NetPC FLASH memory chip. We also use J2 for the product test.
