Specifications

does not poll the transceiver and uses internal data.
It is NOT recommended you use this protocol to synchronize a logging software but only to
synchronize Power-SDF or NAp3. Indeed some commands sent by a logging sofware which are not
supported by TRX-Manager may cause a lockup or a malfunction.
Supported settings are:

Speed 4800 Bds, StopBits = 2, Parity None, Protocol = None

Speed 9600-57600Bds, StopBits = 1, Parity None, Protocol = None

Basic format but FI command (Get) supported
Example :
You control a K3 with TRX-Manager from COM1 (38400 bds).
TRX-Manager's Synchro tab is configured for K3 and COM3 (57600 bds).
NAP3 is configured for Setup = Elecraft K3, COM7 (57600 N 8 1), Poll:IF and Poll:VFOB
checked.
COM3 and COM8 are connected using a null-modem cable or VSPE. Now TRX-Manager and
NAP3 are synchronized...
TRX-Manager (Synchro tab)
With NAP3 + K3, All SSB Offsets = Zero
With [NAP3+TRX-Manager], offsets for CW and DATA modes have to be set (here CW =
550Hz) !
Global Offset = ~-6000 (to be determined).
