the signal rounds on the P2 “b” row, as established by the VMEbus specification, can be used for the RS422 port signal ground. Since the PN4 signals and J1 signals are in parallel and are not buffered, it is not possible to use both connections simultaneously. The UARTs operate at ...
还有就是rs232要求接口能够承受-25～25V的电压而不损坏。 TRANSMITTED SIGNAL VOLTAGE LEVELS:Binary 0: +5 to +15 Vdc (called a “space” or “on”)Binary 1: -5 to -15 Vdc (called a “mark” or “off”)---RECEIVED SIGNAL VOLTAGE LEVELS:Binary 0: +3 to +13 VdcBinary 1: -3 to -...
Voltage Output Levels: A logic gate interprets certain input voltages as high (logic 1) or low (logic 0). TTL (transistor-transistor-logic): A signal above 2 V is interpreted as logic 1 and a signal less than 0.8 V is interpreted as logic 0. The output voltage ranges between 0-5 V...
Determinism is obviously required for an alarm signal that must be distributed in real time. Fieldbus networks are also robust. Industrial networks must often guarantee gas-tight connectors and operate over the industrial temperature range of -45°C to +85°C, A fieldbus network can accommodate ...
connectingPLCs and industrial PCs to field sensors and actuators. One fieldbus advantage is determinism, meaning that signals are received in real time, and the recipient immediately provides an acknowledging signal. Determinism is obviously required for an alarmsignal that must be distributed in real...

protocol implemented. Hence, to check if there is any issue in the device, I would apply a 5V clock signal either A or B while keeping the other connected to GND2. The R output should match the signal on bus if clock is applied to A and should be inverted if the...
RS-422 is a unidirectional, full-duplex standard for electrically noisy industrial environments. It specifies a single driver with multiple receivers. The signal path is differential, and handles bit rates above 50Mbps. The receivers' common-mode range is ±7V, the driver output resist...
