URT-1 multifunction serial signal converter, in order to facilitate the user to debug and use SMS and SCS composite Feite series serial servo design.
URT-1 integrated USB serial port chip, combined with linear low-voltage differential voltage regulator circuit, USB signal can be easily converted to 5V or 3V3 serial signal level.
In the URT-1 board, the 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 a hardware circuit, hardware automatic diversion, without the use of additional IO enable control, reduces the occupation of MCU port burden and code simple.
USB port using USB MINI interface; UART interface with 2.54-row spacing general; SMS series servo interface using the 5264-4AW interface can be directly connected to the steering gear; SCS series servo interface using the 5264-3AW interface can be directly connected to the steering gear.
The working voltage of SMS and SCS series servo fit is not the same, reuse requires a different working voltage, and power supply port, and can also access the SCS from the SMS section of the step-down power supply high voltage after making the system with a power supply to provide power.
Because the power port has an overcurrent limit, the maximum is 6A, so it is necessary to do additional power distribution processing in the actual application of the serial connection of more servos. URT-1 is only used for signal conversion.FE-URT-1 Multi Function Serial Signal Converter Module
