      Clear-Com EF-701M Four Wire RS-422 Interface with Call Signal

      4-Wire Interface with Call Signal, Matrix-to-Party-line

      The EF-701M interface converts a single channel of standard or TW party-line intercom to four-wire audio, while also converting call signals to RS-422 data (and back). The resulting four-wire audio plus RS-422 data can then be sent to a Clear-Com Matrix port, fiber-optic converter (modem) or connected to another EF-701M over twisted-pair cable such as CAT-5E.

      The EF-701M 4-Wire and Matrix Direct Interface is a flexible and powerful tool for c

                                  eBOX GPI8 is an uncomplicated Ethernet/GPI interface for users who need GPI functions, but have no need for the advanced serial over ethernet capabilities offered by the original eBOX. It provides the added benefit of including the eBOX IO functionality (with Opto-Isolated Inputs and Relay Outputs) and it's sBOX compatible.

                                  eBOX GPI8 simplifies long distance cabling by using IP addressable, point-to-point architecture to send control messages over existing 10/100 BASE-T wiring. It's ideal for LAN

                                                  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.
