3.2 CONFIGURING THE SOFTWARE SWITCHES
The Model 1095 features a menu-driven command system that
allows you to monitor and configure your Model 1095 stand alone unit.
There are two modes of operation for the Model 1095 control port:
Monitor and Configuration. These are described in more detail below.
Following the Model 1095 setup is a description of how to setup your
VT100, or equivalent, control port for use with the Model 1095.
3.2.1 Monitor
If you are configuring your Model 1095 through the dip-switches
and you wish to check your configuration or view the status of the
modem you can do so by accessing the control port. In this setup the
user is not able to make configuration changes to the unit because the
hardware dip-switch settings are controlling the configuration of the
unit. If you would like to use the control port to configure your unit see
the Configuration section below for setup information.
3.2.2 Configuration
If you plan to use the Model 1095 control port to configure your
unit, you mus set all of the DIP switches to the ON position. This will
force the 1095 into plug-and-play mode (this configuration is also
required if you intend to have the Model 1095 work in a plug-and-play
environment or use the Model 1001MC to configure the unit).
3.2.3 VT100 Terminal Setup
1) Connect the serial RS-232 port of a VT100 or similar DTE with termi-
nal emulation to the EIA/TIA-561 port of the Model 1095. To construct
an RS-232 to EIA-561 patch cable, refer to the control port pinout dia-
gram in Appendix F. Refer to Appendix B to order a pre-made cable.
2) Power up the terminal and set its RS-232 port as follows:
9600 Baud
8 data bits, 1 stop bit, no parity
Local echo
CR-CR/LF on inbound data
ANSI, VT-100 emulation
3) Power up the Model 1095
4) After power up, the control port displays the Main Menu screen. If the
Main Menu is not shown please review your VT100 setup as described
above.

Based on the DTE rate chosen, the Model 1095 will
automatically select the optimum line rate for the distance. This
selection is based on the lowest line rate that will support the
DTE rate.
