Hardware Description – No specific polarization mandatory Note: There is a diode voltage level between the negative output of the power supply and the “GND”. This could introduce some gap of voltage during measurement and instrumentation. Figure 2-2 . Male JACK Outlet and Wires + - Caution: Do not mount more than one power supply source on AT89STK-06 board. J5 - 9V Battery connector: – Need of a female 2 points connector – Input supply from 6 up to 10V DC (example: 9V battery) – Polarization

Hardware Description 2.4 Serial Interfaces 2.4.1 RS-232C All CAN microcontrollers have one on-chip UART peripheral. Only the asynchronous mode is supported by the AT89STK-06 board. The AT89STK-06 board is supplied with a RS-232 driver/receiver. Only one female DB9 connector assumes the RS-232 connections. A full range of configuration can be set with two Rx lines and two Tx lines. Figure 2-4 . RS-232 DB9 Connections pin 2 RS-TxD pin 3 RS-RxD RS-232 DB9 front view pin 4 pin 6 5 4 3 2 1 pin 5 Gn
