The FE-URT-1 USB to TTL, 485 Bus Programmer offers an integrated USB serial port chip, combined with a linear low-voltage differential voltage regulator circuit, the USB signal can be easily converted to 5 V or 3V3 serial signal level.
In the URT-1 board, serial signal conversion circuit respectively into two different levels of signal, which A road - asynchronous half duplex RS485 level port can be connected to the SMS series servo. B - asynchronous half duplex TTL level single bus port can be connected to the SCS series of the steering gear.
In the URT-1 board in the input and output signal by using asynchronous serial time-sharing using hardware circuit, hardware automatic diversion, without the use of additional IO enable to control, reduces the occupation of MCU port burden and code simple.
