Tracking: This function allows SDR software to track the transceiver attached to Station Master.
NOTE: For specific information, please refer to Appendix B.
The bottom two-thirds of the Radio window is a serial communication monitor. The monitor uses colors and tags
to indicate which device is responsible for the data. Black queries (H1-TX or H2-TX) and grey radio responses
(H1-RX or H2-TX) are from the "host" application (e.g., logger), H1 indicates the host application on the main
CAT port, H2 is the host application on the 2
nd CAT port. Green packets (R-TX and R-RX) are polls/responses
from/to Router and not routed to the application.
Router monitors the communication when the host application performs control and polls the radio periodically
for any missing information (VFO frequencies and mode). Because some applications do not poll the radio
regularly or completely, Router must break this communication to update its internal state. In order to avoid
confusing the application when Router polls the radio, data from the application is buffered and sent to the radio
after Router receives a response to its query. If Router does not receive response to a poll within the time
allowed or does not understand the response, it displays "oldest query discarded" but forwards all data to the
virtual serial port to avoid confusing the application (logger).
USB transmits data in frames with a delay between frames. Router indicates frame boundaries with three dots
(...) when a packet is split between frames.
IMPORTANT: If Station Master Deluxe is to operate in stand alone mode (without Router), the settings
must be saved as power-up defaults using “Device | Store as Power-Up Settings.”
2
nd
CAT PORT
Beginning with version 7.0, Router provides unique control capability: the 2
nd
CAT Port is an intelligent data fork
(software 'Y' connector) that allows a second application to share control of the radio. Router monitors the data
from each application and routes the radio's responses to the correct virtual port.
IMPORTANT: Both applications must use same communication parameters (baud rate, data length,
parity and number of stop bits) for proper operation!
Neither CAT port has priority. Polls/commands from each application are processed alternately. In order to
avoid collisions and avoid confusion due to unexpected data, responses from the radio are returned only to the
application that generated the command. Unsolicited data from the radio such as automatic frequency/mode
updates (Icom "transceive" packets or "Auto-information" data from Kenwood, Elecraft and recent Yaesu
transceivers) are forwarded to both CAT ports.
Due to physical limitation of data channel throughput on radio and the controller capabilities in various
transceivers, there are several important rules which must be observed.
●
Total data throughput from both loggers must not exceed maximum throughput of the radio control port
and transceiver controller. In other words, the polling rate from one application may need to be
decreased to provide data space for the second application and vice versa.
●
Applications must be tolerant of delayed responses from the radio. Each logger must wait patiently for
radio response while another logger communicates with the radio.
●
Due to protocol deficiencies in handling VFO split commands with many transceivers (particularly
Icom), split mode must be initiated and ended by only one application and manual split control (from the
front panel of the radio) should not be used.
NOTE: Although Router has been tested extensively using many different applications for the CAT and
2 nd CAT ports, micro HAM cannot guarantee proper operation with every possible combination of
software.
