Independent channels are established for two-way (full-duplex) communications. The RS232 signals are represented by voltage levels with respect to a system common (power / logic ground). The "idle" state (MARK) has the signal level negative with respect to common, and the "active" state (...

RS-422 threshold voltages refer to the differential voltage between RS-422_p (X) and RS-422_n (X), with ‘X’ for the input line. Environmental Specifications# Operating Temperature Range-25–80 °C, not moving Plug Specifications# ...
Driver Output Levels FIGURE 2. Application of RS-422 Data to an LVDS Receiver The R1, R2, and R3 resistor divider network collectively is a total differential load of 100Ω to match the characteristic impedance of the transmission line and reduces the typical RS-422 differential signal ...
USB, or Universal Serial Bus, hardware protocol uses a single pair of differential conductors to transmit data at speeds up to 12 Mbps. It uses logic levels of 5V and 0V, which are favourable for embedded applications, and the cables are typically shielded which provides good robustness to ...

They are also robust to ESD events, with high levels of protection to human-body model specifications. These devices combine a differential driver and a differential receiver, which operate from a single power supply. In the ?HVD1785, ?HVD1786, and ?HVD1787, the driver differential outputs ...
The receiver output (RO) is ensured to be High when the inputs are left open. The receiver can detect signals as low as ±200 mV over the common mode range of ±10V. The receiver outputs (RO) are compatible with TTL and LVCMOS levels.为...
Extended Protection Against IEC Surge, EFT, ESD And Overvoltage Faults An RS485 transceiver used in an industrial environment can be exposed to extremely high levels of electrical overstress due to lightning surge, electrical fast transients (EFT) from switching high curren...
The voltage levels for RS-422 are 0 to 5VDC (differential TTL). First verify that the host computer will communicate correctly when directly connected with a loopback cable. Then you can test a Prizm RS-422 channel. With a Submux and RS-422 daughterboard in both the ROV and surface ...
