update. The display should increment till it reaches the end of file and then reset if no errors
occur.
Color Display Protocol
SeaGauge-Remote Senor unit supports remote color displays directly attached to either or
both serial ports. The Remote Color Displays use a propriety serial protocol to convey
graphic type, screen position, and display values. The protocol issues commands for each
display element on the currently active screen. The elements and positions are configured
with the vD ash software and downloaded to the unit’s firmware tables. The SeaGauge-
Remote sensor unit contains graphic position information for all supported displays and uses
the stored information to construct the screen image.
The protocol is a fixed length ASCII text string

Each Remote Color Display interprets the protocol information to construct the desired
graphics
Graphic Type – stars with lower case “m” followed by three digit index for type of graphic
to display. Possible options are Large Dials, Small Dials, Bar Graphs, vertical Bar graphs,
Large text boxes, small text boxes, indicator boxes, switches, and more.
X,Y Screen Position – fixed three digit X and Y coordinate to place upper Left corner of
graphic element. Range is dependent on display resolution and size.
Graphic Index Number – three digit number that defines which graphic element stored in
the display to render. Value is based on dial lookup (last 2 digit HEX) from calibration tables
and provides for animation of gauge needles and bar graphs
Sensor Value – four character sensor display value from calibration table. Lookup is based
on sensor voltage
Sensor Label – eight character display label entered in the vDash software to describe each
of the 16 possible sensor inputs.
Each Port on the Remote Sensor unit can be configured for NMEA 0183, NMEA 2000, or
propriety Color Display. If a remote color display is attached directly to the port, then this
protocol must be selected.
