DL2000-KXM: DF1 Multi-Drop Master


 
The DL2000-KXM is a freestanding, compact, serial interface to A-B's DH+ network. This unit is a half-duplex master that interfaces serial devices using A-B DF1 half-duplex slave (multi-drop) protocol to A-B DH+ networks. The -KXM receives messages from DH+ nodes such as PLCs, converts them to A-B half-duplex master (multi-drop) protocol and retransmits them to devices such as A-B's 1747-KE. This product enables remote communications to A-B serial devices that must be set to half-duplex in order to control RTS/CTS handshaking to devices needing it (i.e. single channel radio modems).
