The Pilot™ device conforms to the RS-232 standard but does not support hardware flow control. Additionally, in the CAN specification hardware, only the transmit line for RS-232 is provided. For the full RS-232 specification Pilot™ device, both incoming (RX) and outgoing (TX) data are supported.

A wide range of baud rates and bit packing formats are supported. All well-known rates up to 115200 baud are supported. Unusual baud rates may be supported but internal clock limitations may mean that certain rates are not possible – it is sometimes possible to correct for such errors by slightly misconfiguring the baud rate of the Pilot.
