PFC530 Stand-Alone


PFC 530W.png (323.93 Kb)

This is a GPS that simulates a Garmin GNS 530W.

It consists of standard GNS 530 controls and a monitor and requires external software to operate. As of this writing we are offering RealityXP to drive the operation.

For the PFC 430 LCD and PFC 530

This new code supports legacy 530 hardware and future upgrades, as well as the new PFC 430 LCD. The PFC 430 LCD is functionally identical to the PFC 530 except for the absence of a VNAV button, so we made the hardware mutually compatible; as a result they use the same firmware.

Backlight LED Control Mode

PWM Control

The first run of PFC 530 panels used Pulse-width modulation to control panel and button brightness. Unfortunately it caused interference with the monitor, so we found a way to drive the LEDs with a programmable current controller. If you're having trouble with monitor interference, consider contacting Tech Support; it may be possible to upgrade your unit.

Note that version 4.xx firmware uses a newer PWM technique than version 1.xx firmware. This new technique will mitigate interference with the monitor, and may even eliminate it altogether. Unfortunately, field programming is not possible at this time, so the unit will have to be sent back for an upgrade regardless.

Current Control

Later 530 units (current as of June 2017) use a programmable current control driver in place of the PWM driver. It maintains a regulated current flow, instead of constantly switching on and off like PWM, and so does not produce EMI.

Rev C Hardware

A hardware update is being planned, but no release date has been set. This setting will work for the new hardware.

PFC 430

The PFC 430 LCD has a jumper that forces the firmware to automatically adjust for the 430 hardware. The Backlight LED Control Mode setting is irrelevant for the 430 and changing it will have no effect.

The 430 LCD design includes an LED driver that gives us finer control over its outputs than the older 530 design, but as it uses current control, it produces no EMI.
