Using TTL for additional Com Port and/or FSK
« on: 2015-01-17, 16:59:50 »
I am using the K3/0 Twin configuration and would like to use the TTL connection on the control unit for PC to Radio CAT to free up COM1 for a pass through for other devices. It appears I should be able to do this with one of the DB9 Serial to TTL devices using the MAX2323, or a USB to TTL converter.  Also, optionally I would like to use the TTL on the control unit for FSK with a level converter from RS232 TxD instead of the USB input. Also is it possible to change the usb port to an RS232 with a TTL converter? Any possibilities here?
