IO Connection

Advanced Navigation offers two pre-terminated IO breakout cables (one for the RS232 version and one for the RS422 version) for quick connection to Motus. The evaluation kit USB Cable is supplied as a part of the Motus Evaluation Kit. See Evaluation Kit.

Rugged Evaluation Kit USB Cable

The evaluation kit is supplied with a 2 metre cable with a Motus ODU plug on one end and an overmoulded RS232 to USB converter on the other end, please see Evaluation kit USB cable. The cable is the same 9 wire cable supplied with unterminated ODU cables and all 9 wires are connected on the ODU end. If required, it is possible to cut off the overmoulded RS232 converter to get access to all the individual wires. The chip used in the overmoulded RS232 converter is an FTDI FT232R and supports baud rates of up to 2,000,000 baud.

Optional Breakout Cables

Advanced Navigation offers pre-terminated breakout cables for access to all of Motus' pins. There are two breakout cables — one for RS232 communication and another for RS422 communication. All external signal and power connections are supported with 2 m of cable. The breakout cables are an optional extra and are not supplied as standard with the evaluation kit.

RS232 Breakout Cable (A503-SDC20753)

The RS232 interface cable is provided with industry standard 9 pin DSUB connectors for each of the two RS232 communication channels and GPIO pins.

Please note that this cable is only applicable to the RS232 version of Motus (part number MOTUS2-RUG)
