NetBurner Quick Start Guides
MOD-DEV-70 Carrier Board

Configure the Default Serial Port

The hardware features on the carrier board help you evaluate your peripheral connectivity and to configure the core module. DB9 connectors use the onboard RS-232 level shifter, allowing devices to connect via the serial ports. Extension headers make it easy to connect to a daughterboard or wrapping board for your specific application. The USB port can be used to monitor UART0 and/or power the board.

Most development boards include two serial ports. UART0 serial is routed to the USB port and to the DB9 connector labeled UART0. UART1 is routed only to the DB9 connector labeled UART1. The default mode for UART0 serial is through the USB port. To change the default mode, set the specified jumpers below to the desired position.

JP2,JP3 UART0 1 [2 3]

Using ADC and DAC Peripherals

In order to successfully use the ADC and DAC peripherals, to jumpers will need to be set on the MOD-DEV-70. These connect the 3.3v and ground references that are used by the peripherals.

Power the Development Board

All NetBurner development boards are designed to be powered by a standard micro USB cable or a 7.5V DC power supply. The development board is shipped in a state designed to be powered by USB. To change the power mode, set the specified jumper below to the desired position.

Plug in the Module

After installating the NNDK software, it's a good idea to plug in your module and connect to it to verify that the network and USB driver are properly configured.

To proceed, carefully insert the NetBurner module in to the non powered development board that is included with your kit. All network modules plug in to the board with the Ethernet jack facing the outside edge of the carrier board. If applicable, plug in an Ethernet cable in to the module.

A crossover cable is not required in any network configuration. The network PHY includes Auto MDI/MDIX, which will automatically adjust to make link over both crossover and straight-through cable types.

For more information on how to configure the carrier board to power the module through the barrel jack or the USB jack, please see the section of the manual on the MODDEV70Info, earlier in this guide.
