Abstract

The apparatus (13) connects, via a communication system having at least one communication device 16, an RS485 local-area network to at least one other network. The apparatus includes a modem (15) for transmitting and receiving data messages and an interface (14) for interfacing the modem (15) to the communication system. The interface includes: a first input and a first output for, in use coupling the interface (14) to the modem (15), a second input and second output for coupling the interface (14) to the communication device (16), a buffer means (46,53) to generate a request to send (RTS) message to the modem (15) and a delay means (42,43) to simulate a clear to send (CTS) message for the modem (15). This allows the connection of an RS485 network to another network because the necessary modem commands request to send is generated and clear to send is simulated.
