    I find myself in need of a device that can communicate with a two-way radio that has rs232 input/output for control and display of operating frequency @ 9600 baud, 8 bits, 1 stop and no parity. Simple (16 x 2) display, switches for frequency set. I need someone to design the hardware and program the RPi. I figure a raspberry Pi plus a display and rs232 interface will do it, I just don't have time to learn enough RPi to do the design myself. But I do have time to assemble and test the hardware/software. What I need is an interface to control a communication radio from a remote location. The radio is mounted in the front seat of my airplane and the control will be mounted in the back seat. I need to be able to select a frequency from the remote location and then ...

    We need an easy solution to convert 8 or more RS232 interfaces to an RS485 bus. The system must add an address to the existing RS232 protocol when sending from rs232 to the RS485 but on the other side, when something is sent on the RS485 bus the system must strip the address and send it to the correct RS232 interface. This is to connect different serial rs232 communications to one bus. the solution must be stable with fixed connections, so no USB. we prefer esp32 but another micro controller can be used. When a pcb is needed we also need the pcb layout.
