As RS-485 requires the e-meter nodes to be networked in a bus structure (Figure 2), the interface bus can be designed for half-duplex or full-duplex transmission (Figure 3). Figure 2. Bus structure of ...

Sunnyvale, Calif.—Maxim Integrated Products' MAX13450E/MAX13451E RS-485 transceivers integrate software-/pin-selectable, dual-termination (10ohm/120ohm) resistors to simplify RS-485 network ...

During RS-485 network operation, either all drivers will be passive (the idle bus case) or one driver will be active. 3 Power dissipation in the active driver is the sum of the power dissipation ...

The RS-485 standard defines a popular and widely used serial data interface and network that’s been in use for over 30 years. It’s found in factories, process control plants, building ...

Renesas' new RAA78815x Family of 5V RS-485/422 transceivers ... devices meet both the RS-485 and RS-422 communication standards and are ideally suited for a variety of industrial network, ...

Robustness and reliability have made RS-485 an industrial workhorse. A minimum differential signal swing of 1.5V and reliable operation over common-mode voltages ranging from -7V to +12V have ...

What is the difference between RS-422 and RS-485 and do you know when to use which one? What is the difference between RS-422 and RS-485 and do you know when to use which one? How many devices can you ...

Internal RS-485 bus controller Additional info: The internal bus controller (PC plug-in card) serves as an interface between the PC and the RS 485 network in access control and time recording systems.

With no change to associated computer hardware or software, the device, called ADAM-4520A, transparently converts RS-232 signals to RS-422 or RS-485. It “allows users to take advantage of RS-422 and ...

Renesas has introduced the RAA78815x family of 5V differential RS-485/422 transceivers with electrical fast transient (EFT) immunity – ±5000V – and ESD protection of up to ±16,000V.
