3. Getting Started
This chapter provides a brief introduction to the procedures you’ll use to
communicate with the modem and access the configuration menus. For detailed
instructions about installation and configuration, refer to
Chapters 4
through
6
.
3.1 Applying Power to the Unit
Connect an appropriate power source to the modem. The modem is available in
both AC- and DC-powered versions.
• AC model (MD960A): Set the voltage selector switch (located on the modem’s
back panel) to the appropriate voltage. Connect the supplied power cable to
the receptacle on the modem’s back panel, then connect the plug to a suitable
AC outlet.
• DC model (MD960A-D48): Remove the protective plastic cover from the DC
terminal block, switch off the DC power source, then attach the wires from the
-48 VDC power source to the screw terminals. Connect your ground line to
the grounding screw, then replace the protective cover and switch the DC
power source back on.
CAUTION
Only operate the modem with the type of power source indicated on the
instrument nameplate. If you are not sure of the type of power service
available, please contact your local power company.
After connecting the modem to the power source, put the power switch in the ON
position. The ON indicator will light, and after a brief pause, the RDY indicator will
begin to flash.
3.2 Connecting a PC to the Console Port
For this overview, we’ll connect a PC to the modem’s console port. This will allow
you to access the command mode and display the menus that are used to select
configuration parameters, check connection activity, and define and display user
passwords.
NOTE
Although this overview demonstrates the procedure for communicating
with the unit via the Console Port, you can also access the Command
Mode via modem as described in Section 5.1.2.
