  • Page 58: Synchronous Interfaces

    AR Router Asynchronous interfaces follow the RS-232 standard. A range of speeds is selectable using the SET PORT command from the Interfaces chapter of your router’s Software Reference. Not all signals need to be connected. In particular, both DCD and CTS are not required unless the interface has been specifically set up to use them.

  • Page 59: Ethernet Interfaces

    Hardware Reference data, while asynchronous modems don’t require a clock and rely on the inherent framing provided by the start and stop bits. Normally, any modem 9600 bps or faster will be synchronous. The router can be connected to other remote routers to form a wide area network (WAN), using synchronous modems connected to the synchronous interfaces on the router’s rear panel.
