avoids frequent and undesired tuning of the controller near the limits of a segment.

Ck Buffer checked is recommended with STPIR. If checked, the program checks for an empty

buffer before sending any new command. This reduces the number of collisions but the

program may lock up with some comm drivers (like Prolific).

The SteppIR window

The SteppIR window opens from the Tools/SteppIR submenu and provides various functions

and displays.

SteppIR Window (DATA-OUT)

In some cases of operation (i.e. reversing TX/RX while Split is ON) you may find necessary to

unchek the Auto button to disable frequency tracking (unlike the Interface ON/OFF function,

Auto OFF keeps the controller connected); ->> allows manual update of the controller.

Additional options are provided from the Options dialog:



Set OFF VOX allows setting OFF VOX while tuning for SSB and/or CW (only if your

transceiver provides the corresponding CAT commands),



Correction for 8.50MHz to 9.20MHz fixes a firmware's bug which does not accept

frequencies between 8.50 and 9.20MHz (allows acceptable tunings for SW listening:

8.5-8.85=8.5MHz, 8.85-9.2=9.2MHz). This problem has been fixed by SteppIR for the most

recent firmware.



Polling interval (ms): delay in ms between status commands. 1200ms is the default. If

your interface locks up frequently, please try to increase this value.

Notes



If the current frequency of the antenna is not displayed, press the Interface button to wake up

the controller,



If you use STPIR mode and connect the cable to DATA-IN, frequency updates are processed by

the controller but the SteppIR window is NOT usable (commands are inoperative),



In native mode (connected to DATA-OUT), if the controller does not track properly or COMM

ERROR is displayed... please try switching Off/On the Transceiver Interface (using the Interface

button) or the Controller to resume normal operation,



If COMM ERROR appears too often, please try to uncheck REAL-TIME and to increase the polling

interval (up to 3000ms).



Defaut for Stop Bits is 2. In some cases it appears working better with Stop Bits = 1.

SteppIR: Limitations

The SteppIR controller firmware is limited to due to the lack of memory space on the
