00835-10, 011-00864-10, 011-00864-11 and GPS 500 part number 011-00562-10, 011-00863-10, 011-
00863-11. For applications requiring secondary or alternate power bus input.
To operate the GNS 530 P/N 011-00550-00 COM transceiver in a 14-volt aircraft, A 14
to 28 volt converter such as a KGS Electronics models RB-126 or UC-14-28 or
equivalent must be used. The voltage converter should include exactly one short-circuit
protection device on its output, such as a circuit breaker. P5002-11 and P5002-12 supply
power to the COM transmitter. The other power input pins (P5001-19, P5001-20, and
P5006-44) accept 11-33 Vdc. GNS 530 P/N 011-00550-10 and 011-00550-30 accepts
11-33 Vdc on all power inputs. Refer to Figure F-10 on page F-21.
A power connection on P5006-44 is only required if NAV SUPERFLAG or G/S SUPERFLAG is utilized.
The power inputs P5001-19 and P5001-20 provide power for all functions of the 500 Series unit except the
COM transmitter and the NAV & G/S SUPERFLAG outputs.

The 500 Series unit can be configured to track 28 Vdc, 14 Vdc, 5 Vdc or 5 Vac lighting buses using these
inputs. Alternatively, the 500 Series unit can automatically adjust for ambient lighting conditions based on
the photocell. Refer to section 5.2.6.
