Figure 3-1 shows a 250-kHz (500 kbps) square wave in the following configuration on an oscilloscope:

• Channel 1 – TXD via TP1: vertical position = 2.5, vertical scale = 5 V per division
• Channel 2 – CANH via JMP4: vertical position = –2.5, vertical scale = 1 V per division
• Channel 3 – CANL via JMP4: vertical position = –2.5, vertical scale = 1 V per division
• Channel 4 – RXD via TP3 or JMP2 position 3: vertical position = –3.5, vertical scale = 5 V per division
