That sufficient power is being applied to operate the device. For power-stealing devices such as a converter, it is an indication The Telebyte logo shown on the LCD display indicates the unit is Problem, it provides information as to the status of the local link.
It will assist in the initial installation and check out thereafter Your new Telebyte product incorporates the patent-pendingĭataSpy feature, an LCD display designed to provide meaningful information
The Model 365 has the patent-pending DataSpy feature for installation The ModelĢ85 comes equipped with TD and RD LED's to verify operation while The Model 285/365 comes equipped with a five-positionĭip switch to set the operating mode and a DTE/DCE switch. Furthermore, the RS-485 mode is selectable for two-wire orįour-wire operation. The Model 285/365 Superverter is a unique interface converter thatĪllows the user to operate in RS-232 to RS-422 or RS-232 to RS-485

Total Number of Drivers and Receivers on One Line. The following table compares mode of operation, total number of drivers and receivers, maximum cable length, and maximum data rate. All National Instruments RS-485 boards will work with RS-422 standards. For both communication protocols, you should provide your own termination. Since RS-422 is a subset of RS-485, all RS-422 devices may be controlled by RS-485.īoth protocols have multidrop capability, but RS-485 allows up to 32 devices and RS-422 has a limit of 10. Any of the slave devices on an RS-485 bus can communicate with any other 32 slave devices without going through a master device. RS-485 was made to address the multi-drop limitation of RS-422, allowing up to 32 devices to communicate through the same data line. RS-485 is a superset of RS-422 and expands on the capabilities.
RS-422 is also specified for multi-drop applications where only one transmitter is connected to, and transmits on, a bus of up to 10 receivers. RS-422 sends each signal using two wires to increase the maximum baud rate and cable length. It provides a mechanism for transmitting data up to 10 Mbits/s.

RS-422 (EIA RS-422-A Standard) is the serial connection used on Apple computers. Note that RS-422/RS-485 interface is not available on most IBM PCs. Some RS-232 boards sold by National Instruments support baud rates up to 1 Mbit/s, but most devices are limited to 115.2 kbits/s. RS-232 also uses a Full-Duplex transmission method. RS-232 only allows for one transmitter and one receiver on each line. RS-232 is the most common serial interface and ships as a standard component on most Windows-compatible desktop computers. What are the primary differences between RS-232, RS-422, and RS-485 serial interfaces?
