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.
