It can be used for the development, testing, management and maintenance of CAN networks, as well as recording, sending, receiving and analyzing CAN bus data. However, when we look at the internal structure of USB CAN, we may find that there is a 120Ω resistor on the core board. Let's take a look at the role of the 120Ω resistor.\u003c\/div\u003e\u003cdiv style='font-family:ui-sans-serif, system-ui, sans-serif, \"Apple Color Emoji\", \"Segoe UI Emoji\", \"Segoe UI Symbol\", \"Noto Color Emoji\";font-size:16px;font-weight:400;line-height:24px;text-align:start;white-space:normal;color:rgb(0, 0, 0);background-color:rgba(0, 0, 0, 0);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;display:block' align=\"start\"\u003e\u003c\/div\u003e\u003cdiv style='font-family:ui-sans-serif, system-ui, sans-serif, \"Apple Color Emoji\", \"Segoe UI Emoji\", \"Segoe UI Symbol\", \"Noto Color Emoji\";font-size:16px;font-weight:400;line-height:24px;text-align:start;white-space:normal;color:rgb(0, 0, 0);background-color:rgba(0, 0, 0, 0);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;display:block' align=\"start\"\u003eThe 120Ω resistor in USB CAN is indispensable. In USB CAN, this resistor can provide a stable physical link and absorb reflections at the endpoints. When we use USB CAN for single-node loopback test, the 120Ω resistor must be present. We need to make it form a complete loop to complete the loopback test, otherwise it cannot be realized.\u003c\/div\u003e\u003cdiv style='font-family:ui-sans-serif, system-ui, sans-serif, \"Apple Color Emoji\", \"Segoe UI Emoji\", \"Segoe UI Symbol\", \"Noto Color Emoji\";font-size:16px;font-weight:400;line-height:24px;text-align:start;white-space:normal;color:rgb(0, 0, 0);background-color:rgba(0, 0, 0, 0);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;display:block' align=\"start\"\u003e\u003c\/div\u003e\u003cdiv style='font-family:ui-sans-serif, system-ui, sans-serif, \"Apple Color Emoji\", \"Segoe UI Emoji\", \"Segoe UI Symbol\", \"Noto Color Emoji\";font-size:16px;font-weight:400;line-height:24px;text-align:start;white-space:normal;color:rgb(0, 0, 0);background-color:rgba(0, 0, 0, 0);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;display:block' align=\"start\"\u003eWe also need to know that every detail design of USB CAN equipment is the result of thousands of tests.
