CAUTION
To operate the GNS 530AW (28 VDC units listed in Table 3-1) 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, P5001-15, P5001-72, and P5006-44) accept 11-33 VDC. Refer to Figure H-4.
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 500W Series unit except
the COM transmitter and the NAV & G/S SUPERFLAG outputs.

The 500W Series unit can be configured to track 28 VDC, 14 VDC, 5 VDC or 5 Vac lighting buses using
these inputs. Alternatively, the 500W Series unit can automatically adjust for ambient lighting
conditions based on the photocell. Refer to Section 5.3.6 for configuring the lighting inputs.
