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.

4.2. 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.

4.2.2. 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.

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.

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.

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.

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. If both signals are needed, one of
them can be connected to a free port at the header X16 (CD) with a cable. With
the potentiometer P1, the frequency of the square wave output signal of the
pulse generator output can be varied between 1300Hz and 14kHz.
