3.0 OPERATING INSTRUCTIONS
3.1 Power-on Operation
When the RDMS is powered up it defaults to a modulation based on what mode(s) are
installed. For units with more than one modulation present, the default is determined by the
following table.
Startup Order
Modulation
1
Legacy PSK
2
PCM/FM (Tier 0)
3
SOQPSK (Tier I)
4
Multi-h CPM (Tier II)
Table 2. Default Modulation Startup.
For units with the non-volatile memory option (NV) present, the RDMS will only default to
the modulation according to the preceding table when a modulation is
not
saved in the
Flash memory by the user.
3.2 RDMS Serial Control Protocol
The RDMS is controlled via a simple three-wire serial interface (transmit, receive, and
ground). Configure your controller’s serial port to the following settings:
•
Baud rate of 115,200
•
8 bits
•
No parity
•
1 stop bit
For setup and configuration via a standard Windows-based PC, Quasonix recommends
the use of
Terminal
, a flexible, full-featured control interface that is included in the RDMS
Product CD. Otherwise, one can use
HyperTerminal
, included with the standard Windows
installation (Start -> All Programs -> Accessories -> Communications -> HyperTerminal).
If you have your terminal program active when you apply power to the RDMS, you will see
a welcome message as shown in Figure 5 below.
