Select “Save” from the File menu to save the current
session. This creates a connection icon with the name you
assigned in the HyperTerminal group. To use the configuration,
double-click the connection icon in the HyperTerminal group.
When the HyperTerminal window appears, press [Enter] a
couple of times. The router’s login prompt will appear.
CONNECTING TO AN ETHERNET LAN
To connect the AR720 router to an Ethernet LAN, follow
these steps:
1
The Ethernet port on the AT-AR022 Ethernet PIC is a
10 Mbps port with dual AUI and TP interfaces. Connect the
Ethernet LAN to only one of the interfaces. The PIC will
automatically sense which interface is in use. The Ethernet port
on the AR720 base unit is a 10/100 Fast Ethernet port with a
single RJ45 TP interface.
2
To connect the AR720 to the Ethernet LAN via a TP
interface, use the supplied CAT 5 Ethernet cable or an
approved equivalent. To connect the AR720 to the Ethernet
LAN via an AUI interface, use a transceiver.

Check the operation by observing the state of the LEDs on
the rear panel of the router or PIC. The

LED (if present) will be lit when the Ethernet port is connected
to a hub, PC or a LAN with at least one other device attached.
CONNECTING TO A LEASED LINE CIRCUIT
To connect the AR720 router with an AT-AR023 SYN PIC to a
synchronous leased line circuit, follow these steps:
1
Using the appropriate approved transition cable (RS-232,
X.21 or V.35), connect the synchronous port on the rear panel
of the AT-AR023 SYN PIC to the telecommunication service
provider’s NTU.
