It is a remote antenna switch who can control up to 5 different aerials. It can be interfaced with the radio to automatically select the proper antenna depending on the VFO's band. It can also be controlled by a software running under Windows.

RSW 5 is based on a Atmel microcontroller which make the device very versatile to the user's need. It can be controlled in three different ways.

1) manually - by pushing the buttons on the front panel

2) automatically - depending on the FT1000MP selected band

3) remotely - by a software running on a PC, through the rs232

For sure :-)

The core is an ATMega32 microcontroller. 6 pins of the micro are continiously read to detect if one of the corresponding buttons is press. 5 buttons are related to the antennas and the 6th is for switching the device from the manual control into the automatic/remote mode. There's a max232 integrate to convert electric RS232 signals into 0v and +5v, needed by the micro. 5 pins more are dedicated to the outputs and depending on the desired antenna makes a transitor activate a 5v relay so to send 12v to the power relais in the remote box. Other more pins are dedicated to control the LCD display. 4 pins read the band directly from the radio and other more pins are connected to the max232.  I have done a specific transformer in order to have a stabilized +5Vdc and +12Vdc. The device is composed by 3 modules: the first is the transformer, the second is the module for the micro relais and the third is the "brain" module.

To configure which antenna should change when the radio changes the band, there's a software. By the software it's also possible to configure the initial message (eg. your call and name) and the name of the antennas (eg. Ant 1 40mt dipole). Furthermore, by the programm it's possible to change the antenna only by the clik of the mouse. The software for PC was written in VB6 and the firmware for the RSW5 in basic.
