for their great work.
UPS Aviation Technologies description:
The SL70 is the smallest, most powerful Mode A/C transponder on the market.
It meets all requirements for use in both VFR and IFR operations. The SL70
SlimlineTransponder is designed to work together with other Apollo avionics such
as the GX and Slimline series GPS receivers. It provides altitude information
required for VNAV and IFR operations through a serial data connection. Pressure
altitude can be provided to the SL70 via a gray code blind encoder or a serial
data blind encoder. This pressure altitude information is displayed on the
transponder display. The SL70 is the only transponder with a built-in
altitude hold feature.
Note:

and download the Operation Manual for the SL70.
Gauge description:
This Transponder radio gauge works close to the real instrument except of the
limitations of FS. It has full functional buttons like the original. It provides
a display with pressure altitude and an altitude hold display. Also a
preselected VFR transponder code is available.
The Indicators:
Indicators are showing up above the corresponding buttons.
If the transponder is replying a signal, the display indicates a blinking bar
above the button IDENT.
The Buttons and Knobs:
See the picture ExplSL70.bmp which gives an overview of the functions.
The power knob switches the transponder on and off.
You can have the power switch always set on and use a central avionic circuit
switch in your main panel to set the power of ALL radios in this package.
Pushing the IDENT button, the display indicates "IDENT" for 20 seconds if the
transponder is not in standby mode.
Pushing the SBY button, the transponder is in standy mode. No signal will be
replied.
Pushing the ON or ALT button, the transponder replies a signal.
Pushing the VFR button, the transponder code will be set to one of the three
built-in VFR codes depending on which *.gau file you have included in your
panel:
- squawk 1200 - USA - use XPDR_Apollo_SL70_us.gau.
- squawk 7000 - most countries in Europe - use XPDR_Apollo_SL70_eu.gau.
- squawk 0021 - Germany - use XPDR_Apollo_SL70_ge.gau.
Set the transpoder code:
Click the large knob on the left or right side to activate the enter mode.
The cursor for the first digit is blinking. Click the small knob left to
decrement or right to increment the first digit. Click the large knob right to
set the cursor at the position of the second digit and click the small knob to
change the value and so on. When finished, click the large knob again to leave
the enter mode. The cursor stops blinking.
Use the altitude hold feature:
If not in altitude hold mode, the transponder displays the pressure altitude as
a 3 digit value (Flightlevel). Climb or descent to your desired altitude then
press the HLD button. The display now shows the +/- difference between the hold
value and your current altitude. If you want to hold any other altitude,
deselect HLD, proceed your next flightlevel and press HLD again.
The built-in altitude hold feature has an altitude buffer of 300 ft. If this
buffer exceeds, the altitude hold display is blinking.
Notes:
This is version 1.0 of this gauge and if any updates are required I will release
them. Send me an email if anything doesn't work as expected.
This gauge is programmed completely new with EASYGauge, a wonderful easy to use
