Only this CANDB9120Ohm connector needs to be connected directly to the DB9 port of the CAN device or can analyzer.

CAN bus communication is defined, PIN2 is L signal,PIN7 is the H signal. The resistance of 120 ohms added between thePIN2 and PIN7 is used to filter out the bus terminal echo interference and ensure the integrity of the communication protocol;

If the 120 ohm resistance is not added, the echo reflection on the communication will be caused, the reflected wave will overlap with the correct wave, resulting in the waveform beyond the CAN level definition range, directly resulting in incomplete communication protocol, thus affecting the accuracy of the communication values;

• BUELEC CANDB9120Ohm CAN bus DB9 pin terminal matching resistance, between pin2 and pin7 built-in high-precision up to one thousandth 120 ohm resistance;
• BUELEC CANDB9120Ohm DB9 Male-to-female interface, plugged directly into the DB9 interface of the any bus analyzer, no need changing exist cable；
• BUELEC CANDB9120Ohm use custom collate, better strength, high temperature resistance;
• BUELEC CANDB9120Ohm power is calculated in accordance with TI's CAN chip communication parameters,suitable for communication error rate has strict requirements;
• BUELEC CANDB9120Ohm Compatible with PCAN,GC-CAN-USB,Peak-CAN,ZLG-USBCAN,VECTOR - CAN,Vechle SPYetc.... most of can analyzer in market;
