2.15.2Zooming ARP, TTM targets

You may zoom in on TTM targets coming into the display. TTM targets can come from a NAVNET connected RADAR, or from other ARP RADAR that is outputting the TTM message. Note: TTM stands for Tracked Target Message. It is a NMEA 0183 data sentence that is an available output from some ARP capable RADAR. TTM target numbers must be displayed to zoom in on tracked targets. This can be done by enabling the target ID number option in the ARP setup menu.
