The first thing to determine would be if the USB to serial is working.
We suggest using TeraTerm terminal program to open the serial port. If you do not get any error in opening the serial port, set the serial port settings to 115200,no parity, 8 data bits, 1 stop bit, no hardware handshaking. (115200,N,8,1)
Then with the port open and the unit connected power cycle the simulator. On startup it print out the version number of the firmware. You can also type help in the simulator. You should see a response.
If you do not see any activity on the terminal program, check the power going to the unit and the cabling/wiring. Since both units were working and now are not working, there is something wrong with either the USB to serial, the cabling, the power going to the unit or the cable/wire hookup.
