The MicroRouter 2270R secondary port is an RS-232 sync/async inter- face. The RS-232 interface is capable of communicating to another router or a PPP client machine over a modem, 56K CSU/DSU, or ISDN Terminal Adapter.

RS-232 Interface

The MicroRouter 2270R includes one DB-25 to DB-25 RS-232 sync/async cable. This cable supports RS-232 asynchronous modems, synchronous leased and switched 56K CSU/DSU’s, and ISDN Terminal Adapters. It can also be used to connect the router’s auxiliary interface to a PC running terminal emulation software, or to a dumb terminal.
