Specifications

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
