1.9.7 TTL UARTx
Congure UARTx control settings. TTL UARTs are buffered. There are a total of three TTL UARTS
available.
Modes
Pins can have multiple functions. The mode drop down menu under input settings is used to set
the main fuction of the selected pin from the pin settings list. After the mode is set the available
settings for that mode will be active and can be set. If the setting is not applicable to the
selected mode it will be grayed out.
Packet Serial - Mode to communicate to the MCP rmware. Packet Serial mode can be forced
active by setting the RTS signal of the Virtual Serial port.
Priority Timeout - Time in milliseconds new data must be received before timing out. As
long as any data is received, even if it is not a valid packet the timeout period will be reset.
Rate - The bit rate to communicate at. Default value is 115200. Valid Range is 300 to
1000000 bps.
Multi Unit Mode - Sets TTL output into open-drain mode, allowing multiple MCP units to use
the same RX connection to the external controller. An external pullup resistor (recommend
values 1k to 10k) should be added to the external controllers RX pin.
