router must first be configured for synchronous operation before
connecting to the device. See Chapter 6 - Basic Configuration Guide
for configuration information.
You may select either dial-on-demand, always up (i.e., redial if down),
or leased line operation. This interface may also be set to receive ISDN
or switched-56 incoming calls.
To connect a device, first make sure that both units are powered off.
Then, simply connect the supplied RS-232 cable between the router and
the device.

Note:
The MicroRouter 900i RS-232 interfaces require that your
asynchronous line communications device be set to supply the RS-232
DCD signal when a connection has been made. A synchronous RS-232
device should be set to provide DSR.

Note:
The MicroRouter 900i includes a special cable to facilitate
connections to RS-232 line communications devices. This cable
includes support for several asynchronous and synchronous control
signals. Off-the-shelf cables generally do not support these signals.
Connecting an Out-of-Band Management Console
If you wish to connect an out-of-band management console, use the
supplied cable and connect to the Console interface on the back of the
MicroRouter 900i. You can use a dumb terminal or a computer
equipped with VT100 terminal emulation.
The default settings for the Console interface are VT100 terminal
emulation, 9600 bps, 8 bits, no parity, 1 stop bit, no Flow Control.
Powering Up the Router
Power up any modem, CSU/DSU, or TA before powering up the router.
This allows the router to immediately sense whether its secondary inter-
face is connected. The exception to this rule is when connecting an
RS232 interface to a CSU/DSU. In such a case, you must power up the
router before powering up the CSU/DSU. At power-up, the router will
take approximately one minute to become visible to CompatiView.

Note:
If you want to use Telnet as a management method, you must
first configure an IP address into the router using an out-of-band
console, or reconfigure the IP address on an IP host or workstation on
the same Ethernet segment as the router. See Chapter 5 - Command
Line Management for more information.
