The figure bellow illustrates the wiring requirements for connecting the DM2436AB using RS-232C communications. This can include a local direct connection to a
computer or other device. The RS-232C standard allows only a single point-to-point communications connection. Using this method, only one RS-232C equipped device may be connected to the serial port of the computer, or other device.The cable used between the computer is a standard RS-232Ccommunications cable with a maximum length of 50 feet (15.2m).RS-485 CONNECTION
RS-485 communications allows multiple devices to be connected on the same bus. Up to 30 devices can be connected on a single RS-485 bus, which consists of a shield twisted pair cable. The overall length of the RS-485 cable connecting all devices cannot exceed 4000 ft (1219m).TOP輸出的腳位圖
