Offset: Number which defines antenna azimuth offset against 0 deg of the internal rotator controller calibration.
Offset range is -180 to +180 deg. Negative value mean counter clockwise offset, absolute azimuth in
range 180-360 deg. Offset is used by the antenna direction control to show and work with proper
absolute azimuth of the antenna – for example when using a 40 meter antenna that is mounted at
right angles to a triband antenna. Offset control works only with SM internal rotator controller.
PA ANT NR: When StationMaster is used with an automatic power amplifier with antenna presets, this number
determines which preset is to be used when this particular antenna is selected for TX.
Serial port functions
Station Master contains one RS232 port that can be used for for control of a SteppIR antenna, provide support
for Icom compatible accessories, or be used as a general purpose serial port.
General purpose, Auxiliary serial port: When Serial port function is set to Auxiliary port, data is transferred
between the "Auxiliary" virtual port defined on Ports tab and the SERIAL port without modification.
Maximum data rate is 19,200 baud. There is no relationship between transferred data and SM
functions.
CAT input: When the Serial port function is set to CAT input, a remote program can control the radio via the
serial port. This is useful, for example, for standalone remote operation of radio without a local
computer with running Router. CAT data is routed from a remote control application (e.g. via some
sort of WAN/LAN-to-serial converter) to the serial port. A valid CAT setting has to be present on
PORT tab, and this setting has to be saved as default prior using this option.
This replicates a similar functionality of the microHAM Band Decoder.
CI-V port: When Serial port function is set to CI-V, SM simulates Icom's CI-V transceive function and
broadcasts the chosen frequency in Icom format (at RS232 levels) even when the transceiver
connected to to the Station Master isn't an Icom radio. The CI-V address and baud rate of simulated
radio is set in appropriate field.
There are five types of frequencies which can be sent: RX frequency, TX frequency, Operating
frequency, VFO A frequency or VFO B frequency. In practice, operation of each setting depends on
the transceiver and its CAT protocol. All settings may not work with some radios.
Acom2000: When the Serial port function is set to Acom2000, SM controls an Acom 2000 amplifier connected
to serial port. SM automatically presets the Acom 2000 to settings defined according to the PA ANT
NUB index. In other words, SM tunes the Acom for the selected antenna before transmitting.
PA ANT NUMB could be unique for each antenna per band, but reserve should skip indexes of
multiband antennas, Acom 2000 supports ten memory slots for each operating frequency segment.
Best explanation is by example. The picture on the previous page shows the index settings for the
following antenna farm:
160 to 10m Vertical
●
80/75m CW/SSB dipole
●
80m four square (4SQ)
●
40m Inverted V for CW usable in range 7.000 to 7.100
●
40m 3el Yagi (whole band) on the rotator but offset 90 degrees CCW from SteppIR
●
20m to 6m 3el SteppIR, antenna is on rotator
●
12m 5el Yagi, antenna is on rotator but offset 90 degrees CW from SteppIR
●
160m to 40m receiving four square with preamplifiers
●
