   Apr 10, 2024 · Minimum amplitudes for an RS-485 driver and receiver. Image used courtesy of Texas Instruments . Signal Swing. The signal swing of an RS-485 bus is much lower than that of an RS-232 interface. This is an important benefit of RS-485, since smaller-amplitude signals allow for simplified circuit design and improved efficiency.

   What are RS-485 wiring methods?

   • RS-485 wiring methods include two-wire system and four-wire system. Four-wire system can only realize point-to-point communication, which is rarely used now. The two-wire wiring method is mostly used. This wiring method is a bus topology, and can connect up to 32 nodes on the same bus.

   What are the advantages of RS485 bus transceiver?

   • RS-485 adopts balanced transmission and differential reception, so it has the ability to suppress common mode interference. In addition, the bus transceiver has high sensitivity and can detect voltages as low as 200mv, so the transmission signal can be recovered from kilometers away. RS485 advantage is the communication between multi-node systems.

   What is the difference between RS-485 and RS485?

   • Because it’s a multipoint specification, RS-485 is much more flexible. Multiple RS-485 devices can communicate without any special modifications or interface circuits, as shown in Figure 1. An RS-485 driver must be able to sustain 32 “unit loads,” meaning 32 receivers with 15 kΩ input impedance.

   Apr 17, 2024 · CAN Bus JST-PH Connector. On the front of the board is the JST-PH connector with the three pins for communicating with the CAN Bus standard. If you use one of our JST-PH 3-pin cables, black wire is ground, red wire is CAN H and white wire is CAN L. The left input on the JST-PH connector is common ground shared between the two CAN connections.
