MRX-900 Operating Manual: Configuration Options

3. Configuration Options
In configuration mode, the
default serial rate for the
MRX-900 is 9600 baud.
Refer to Appendix A (page
15) for a menu navigation
chart to facilitate use of the
configuration menus.
Configuration options are
immediately stored in non-
volatile memory when
selected and become active
after exiting configuration or
power-cycling the unit.
3.0 Configuration Parameters
The MRX-900 is easily configured to meet a wide range of needs and
applications. Configuration is fully menu-driven and requires only a terminal
with a 9600 baud RS-232 port. Configuration mode is initiated by depressing
the Configuration Button on the back panel of the MRX-900 and holding it
for at least two or three seconds. The main configuration menu is then
displayed:

Note that 9600 baud is the default rate for configuration only, and that the
actual data communications rate during operation is user-defined, with rates
from 2400 to 115,200 bps. (With reference to the serial data port,
baud and
bps can correctly be used interchangeably since no modulation occurs to
increase the bit rate over the baud rate. This may not always be the case with
modulated signals transmitted between DCEs.) No terminal emulation is
required, although a “TTY” setting can be used if mode selection is required
by your communications software.
Most menu items are hot-key driven, requiring minimal keypresses to quickly
navigate and set parameters. Current parameters are indicated to the right of
each item in the main configuration menu (see above), and preceded by an
asterisk (
*
) for each chosen option in parameter submenus (shown on
following pages). Configuration parameters are saved in non-volatile
memory as soon as they are selected. This allows quick configuration of the
modem and reactivation in operation mode by either pressing ESC on the
terminal from the main configuration menu, or simply power-cycling the unit
(momentarily disconnecting power to the MRX-900).
3.1 Operating Mode
The Operating Mode partly defines the “personality” of the MRX-900.
When item 1 is chosen from the configuration menu, the following options
are available:
