Relics: Visual Basic Programming: ICOM IC-R8500 remote control

ICOM IC-R8500 Communications Receiver remote control

RadioFrequency (Remote Control Application)

Raimund Forstmeier, a friend from Padova (Italy) has written a very useful program in VB.NET to send frequencies, modes, etc. to the ICOM and ELAD SW2 radio's via RS-232 (serial port). Frequencies, modes and associated descriptions are stored in a text file. Instructions are included in the ReadMe.txt file. You are welcome to download it. Thank you Raimund.

Latest version: 1.6.1 (03 April 2018)

This update includes:

Please read the specific Help-File [ H ] near the [Elad SW2/DUO Receiver]-Button.

Remote control example

Control you IC-R8500 remotely using the Visual Basic Version 5 MSComm Control and your PC's Serial Port.

ICOM IC-R8500 Communicatons Receiver

Following is an example I wrote using the Visual Basic Version 5 MSComm Control which sets the IC-R8500 frequency to 1,234,567,890 Hz:

The ICOM range of communications receivers use variable length binary command sets, that is, ASCII text commands cannot be sent to the equipment using a text-based terminal such as Windows Terminal. It is therefore important to convert the control command set to a format the equipment recognises.

A typical binary command set is FEFE4AE0dataFD
In this example the data field contains the Set Frequency Command and the desired frequency in Hz i.e.
05 is the Set Frequency Command and 9078563412 is the desired frequency. For a complete Listing of Control Command Sets refer to your ICOM Instruction Manual.

Convert the HEX values to Decimal values for each Byte in the binary command set i.e.
FE=254, FE=254, 4A=74, E0=224, 05=5, 90=144, 78=120, 56=86, 34=52, 12=18, FD=253

Thereafter pass the ASCII character of each Byte above to the MSComm Control.

Note: The MSComm Control is named RS232 in this example:
