Rs 485 termination resistor
http://sss-mag.com/pdf/485appno.pdf WebLTC2859 is a half duplex, low power, RS485/422 transceiver operating on 5V supplies. The driver features a logic-selectable low-EMI 250kbps operating mode, and maintains a high output impedance over the entire common mode range when disabled or when the supply is removed. Excessive power dissipation caused by bus contention or a fault is prevented by …

WebRS485 Line Termination Resistor Calculator for power termination configuration. RS485 data transmission lines should always be terminated with a resistor or a combined … WebRS-485 is specified as a multipoint standard, which means up to 32 transceivers can be connected on the same bus. Figure 2. shows a typical RS-422 interface circuit. Although an RS-485 circuit may appear similar, the main difference is in the bus architecture. Figure 3 shows a typical RS-485 appli-cation circuit. RS-422
WebRS485 Termination Both ends of the RS485 communication line is terminated by a resistor, often the resistor is chosen to be 100 ohms. The reason for this resistor is because there is a conflict between fast data rates and the slow speed (by comparison) of the electricity in the wires (somewhat less than a foot in a Nano-second). WebThe Primary features of RS-485 are: • Balanced interface • Multipoint operation from a single 5-V supply • –7-V to +12-V bus common-mode range ... feet or less, a termination resistor is not needed at baud rates of 9600bps or less. If a termination resister is required, a 120Ω or greater should be used. No more than 2
