Multi-serial card, also known as MOXA card, extends multiple RS-232/485 serial ports through ISA bus/PCI bus. Computer manages the corresponding serial ports through random virtual serial port software. It supports Plug and Play function and can be used without any settings.
Interface characteristics: Serial port conforms to EIA RS-232/485 protocol
Electrical interface: DB9 (RS-232/485 serial port)
Working mode: asynchronous work, point-to-point or multi-point, 2-line half-duplex
Transmission rate: 300 bps-115 200 BPS
Cache register: 16 bytes
Use Environment: Temperature: -20-60 C, Humidity: 5%-95%
Transmission distance: RS-485 terminal does not exceed 1200 meters, RS-232 terminal does not exceed 5 meters
