Detailed Description 4.1. JTAG Connector There are three connectors to adapt to the JTAG interface of the NET+ARM CPUs: The 1st is the ARM standard 14-pin connector. The 2nd connector with 8 pins can be used to interface to the FS Forth-Systeme JTAG Booster. The 3rd connector with 20 pins is the Multi-ICE interface. 14-pin connector, X4 Pin Signal Function 1 +3.3V Power Supply for Adapter 3 NC Not connected 5 TDI Serial data input, to NET+ARM 7 TMS Serial mode select 9 TCK Serial clock 11 TDO Serial data output, from NET+ARM 13 +3.3V Power Supply for Adapter 2 GND GND 4 GND GND 6 GND GND 8 GND GND 10 GND GND 12 TRST# JTAG reset 1.) 14 GND GND 1.)

Serial Interfaces The Evaluation Board provides different kinds of serial interfaces. These are RS232, CAN, Ethernet and USB. 4.2.1. RS232 The Evaluation Board provides two RS232-interfaces; COM A and COM B. Both interfaces are fitted with 9-pin SUBD male connectors. COM A is fully equipped with all handshake signals. So a modem connection can be easy supported. COM B only provides the data lines TXD and RXD, without any handshake signals.

CAN The Evaluation Board provides two CAN interfaces; CAN1 and CAN2. CAN1 is fitted with a 9-pin SUBD male connector X9, while CAN2 is available at a 10-pin header with twin rows, X10. Both channels provide the termination resistor, which can be disabled by removing jumper JP4 for CAN1 or JP5 for CAN2. There is also the possibility to place the CAN drivers on the Evaluation Board (this is the factory default), in case a module without CAN drivers is used. In this case the resistors R65, R70 for CAN1 and R81, R82 for CAN2, are not equipped and the resistors R71 for CAN1 and R83 for CAN2 are assembled on the Evaluation Board. It is also possible to insert an opto-coupler for a galvanic isolation of the CAN channels. This can be done by removing R72, R73 for CAN1 or R84, R85 for CAN2 and connecting the wire from the opto-coupler to the pads of these resistors. 16 EVANET User's Manual CAN 1, 9-pin connector, X9 Pin Signal Function 1 NC Not connected 2 CAN_L1 CAN low 3 GND GND 4 NC Not connected 5 NC Not connected 6 GND GND 7 CAN_H1 CAN high 8 NC Not connected 9 NC Not connected CAN 2, 10 pin connector, X10 Pin Signal Function 1 NC Not connected 3 CAN_L2 CAN low 5 GND GND 7 NC Not connected 9 NC Not connected 2 GND GND 4 CAN_H2 CAN high 6 NC Not connected 8 NC Not connected 10 NC Not connected 4.2.3. Ethernet The Ethernet connection is realized by a standard 8-pin RJ45 module jack, X11. For additional information about the data flow, there are two LEDs. LED LE2 shows the Link/Activity and LED LE3 is active for a 100Mbit connection. 17 EVANET User's Manual 4.2.4. USB The Evaluation Board is prepared for future versions of the module which support a USB port. The Evaluation Board provides the possibility either to use the USB channel as a host or as a device. This functionality is chosen by the jumpers J13 and J14. Configuration Jumper J13, J14 Configuration Jumper J13, J14 Connected Pins Function Used connector 1-2 NET+ARM is USB host USB type A, X12 2-3 NET+ARM is USB USB type B, X13 device 4.3. Power Supply The Evaluation Board expects a stabilized 5 VDC (±0.25V) voltage at the X1 power connector. 18 EVANET User's Manual 4.4. Battery Back-up A Lithium battery (3V) is also included on the Evaluation Board when shipped. It supplies both, low-powered SRAMs and the RTC on the module. According to the position of jumper J1 the battery can be connected or disconnected. Configuration Jumper J1 Connected Pins Function 1-2 Battery connected 2-3 Battery disconnected 19 EVANET User's Manual 4.5. System Configuration With the DIP switch S1 some configurations for the NET+ARM CPU can be made. The ON position generates a low-level at the CPU pin.

This is needed to enter the debugger, if the Flash memory is empty, for example. If the jumper J2 is open, the Flash memory is enabled. Configuration Jumper J2 Connected Pins Function 1-2 Flash memory disabled 20 EVANET User's Manual 4.6. User Area The Evaluation Board provides two expansion headers, 2x32 pins each (X16 and X17), with system and peripheral signals, a wire-wrap field, four LEDs, four push buttons, one potentiometer, one buzzer and a pulse generator; all of which can be freely used by the user. 21 EVANET User's Manual Expansion connector X17(AB), X16(CD) Pin 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 22 Row A Address A0 Address A2 Address A4 Address A6 Address A8 Address A10 Address A12 Address A14 Address A16 Address A18 RSTIN# WE# R/W# BCLK CS3# CS4# BE2# BE3# CS2# Data D16 Data D18 Data D20 Data D22 Data D24 Data D26 Data D28 Data D30 Row B Address A1 Address A3 Address A5 Address A7 Address A9 Address A11 Address A13 Address A15 Address A17 Address A19 PWRGOOD OE# TS# TA# TEA# BG# BR# BUSY# + 3,3V GND + 5V + 3,3V GND + 5V Data Data Data Data Data Data Data Data D17 D19 D21 D23 D25 D27 D29 D31 Row C Port A0 Port A2 Port A4 Port A6 Port B0 Port B2 Port B4 Port B6 Port C0 Port C2 Port C4 Port C6 PACK# PINT1# PDATA0 PDATA1 PDATA2 PDATA3 PDATA4 PDATA5 PDATA6 PDATA7 PDATA8 PDATA9 PDATA10 PDATA11 PDATA12 PDATA13 PDATA14 PDATA15 PCS# PRW# Row D Port A1 Port A3 Port A5 Port A7 Port B1 Port B3 Port B5 Port B7 Port C1 Port C3 Port C5 Port C7 PEN# PINT2# PA0 PA1 PA2 PA3 PA4 PA5 PA6 PA7 PA8 PA9 PA10 PA11 PA12 PA13 PA14 PA15 PA16 PBRW# EVANET User's Manual Generating Chip Select signals for the push buttons and LEDs Signal CETAST# active CELED# active A11 1 0 A12 1 1 CS3# 0 0 OE# 0 X With the jumper J18 either the output signal of the pulse generator U3 or the interrupt request signal of the CompactFlash card can be connected to the interrupt input port PORTC3 of the NET+ARM.
