Black Box IC1473A-F-ET Async RS-232 to RS-422 Interface Converter - DB9 Female to Terminal Block
Black Box
Item# BBX-IC1473A-F-ET
For DB9 equipment, if the peripheral operates on the RS-422 signal, use only one DB9 converter. But if the transmitting and receiving equipment only operates on RS-232, use two converters. All provide 115.2-kbps speed for distances up to 4000 feet (1219.2 m). Features: Converts unbalanced RS-232 signals to balanced RS-422 signals. The RS-232 side has a DB9 port configured as DCE. The RS-422 side has a terminal block. This converter operates under extreme temperatures, making it an appropriate choice...

RS-232 & RS422 are a standard communication protocol for linking a computer and its peripheral devices to allow serial data exchange and RS232 & RS422 Interface Products are needed to make this happen. Both RS232 & RS422 define the voltage for the path used for data exchange between the devices. Handshaking is a process in which RS232 & RS422 Interface Products sends a signal to establish a connection between the devices before the actual transfer of data. RS232 & RS422 Interface Productshelp to set the parameters of the communication channel established between two pieces of equipment before normal communication begins. Markertek carries a wide variety of RS232 & RS422 Interface Products.
