Check of ARP and RP board Connection
The system checks the connection of the ARP and RP board every power on. If the CPU on the
SPU board fails to communicate with the ARPA or RP board, the related display does not appear
on the screen, but also the ARP and/or RP line is not displayed on the self-test result display.
ARP-15 vs. ARP-17

Major feature of ARP-17 is;
1) Automatic tracking
2) More target to be tracked. (increared to 20 targets from 10 targets)
3) Guard ring (guard ring targets of 11)
4) Scenario test
5) Reference target speed
