Serial Port Interface
The Crescent V100 offers position and heading data via both
RS-232 and RS-422 level serial ports. The answer of which serial
port level to use resides with the serial port level(s) supported by
the other electronics involved. You may find that the other
electronics need either serial port level or a mixture of both.
The following sections describe the two serial port levels supported
by the Crescent V100.
RS-232 Interface Level
The Crescent V100 features two full duplex (bi-directional) RS-232
serial ports. In addition to outputting data, these ports are used for
firmware upgrades.
Data output from both RS-232 Ports A and B are also output on the
RS-422 ports.
RS-422 Interface Level
The RS-422 standard allows for one device to communicate with
many other devices simultaneously, therefore the RS-422 ports are
only talkers. These ports are in accordance with international
marine standard IEC 61162. See Annex C of the standard for a
description.
