Capen" Subject: Avionics-List: RE: RV-List: Navworx ADS600b and SL70 Cross-posted to make sure everyone can see responses..... I was initially asking them about the differences between connecting pins 3 and 5 of the SL70 to pins 32 and 33 of the ADS600B for control versus connecting pins 3 and 5 of the SL70 to pins 6 and 7 of the ADS600B for altitude data. Their initial response indicated that I only need 3 and 5 to 32 and 33 as that connection will pass control and data messages. They followed up with indicating extended mode or remote mode were also required - I haven't been able to get a direct response to that question. I sent them pdf's of the SL70 install and user guides - my Navworx manual is rev 33 (guessing from the part number) - it doesn't have any references to remote mode for the SL70...but it does reference a remote mode for the GNS480 and GTX330 units. There is a remote ident supress feature common to the ADS600B (pin 35) and the SL70 (pin 19), which NavWorx recommended to connect also. >From reading everyone's manuals, my gut tells me that connecting pins 3, 5, and 19 of the SL70 to pins 32, 33, and 35 (respectively) of the ADS600B is all that is required....no 'programming' in the SL70 - but there are settings in the ADS600B.... This is how I'm planning my installation - unless I get additional/contrary guidance from NavWorx.

Since the MX20 will take in both traffic and weather data streams from the ADS600B and the 400W/500W series will only take traffic, I am seriously considering NOT burdening the 400W/500W box's processor with the data stream.

Capen" Subject: Avionics-List: NavWorx / SL 70 -> Extended mode >From the folks at NavWorx - kudos to them for documenting this...I expect to find it in a NavWorx manual update soon. The SL70 IM is missing the instructions on how to configure it for extended mode. On page 31 of the 2003 Garmin SL70 installation manual, Appendix E Serial Interface Specification, there is reference/clue in the paragraph Message Definitions. Messages are divided into two groups, the Standard Message which is simply the pressure altitude and system status and the Extended Message group which includes the squawk code and all the other good stuff listed in Appendix E. The last sentence references that this is accomplished in the setup mode and saved in the EEPROM. What is missing is exactly how to do this. The procedure is as follows: Reference page 12 of the 2003 Apollo SL70 Installation Manual Post Installation Checkout 1. Put the unit in setup mode: A. To operate the SL70 in the setup mode hold down the IDENT and ALT buttons while turning the power on 2. Turn the large knob to the SL70 config page a. This should be one click clockwise and change from set up to SL70 config 3. Using the small knob: a. Turn to ASRC This is the altitude source page b. The two choices for altitude INPUT are gray or serial i. Unless Navworx can update its software to run at 1200 baud, an encoder capable of gray code and or a serial to gray code convertor such as Dynon Manufactures will need to be used to interface with the SL70. The SL70 will only accept altitude data from an encoder at 1200 baud. ii. So at this point assuming you use the serial to gray converter, set the input to GRAY by: 1. Press the ident button the serial or gray field will start to flash 2. Set to gray if not already indicating gray 3. Press ident again to set into the memory if the setting was changed, if not proceed 4. Turn the small knob one click to set the baud rate a. To select and change the baud rate, press the ident button once, the baud rate field will start to flash b. To interface with the Navworx unit, at present, the baud rate will need to be set to 9,600 c. Turn the small knob until 9600 in displayed and press the ident button again to set into memory 5. Here is what is missing from the manual Turn the small knob clockwise one click to the next input screen a. The next screen is the TX screen The TX is for the message transmit format used on the serial port b. There are two options Standard STD and Extended EXT c. Press the ident button to highlight the field. It will start to flash d. Turn the small knob to set the EXT into the field e. Press the ident button again to set the field 6. Cycle the SL70 power off and turn back on. The SL70 is good to go and should now be set up to control the Navworx unit a. Using the maintenance port on the Navworx, set the Input screen to SL70 and DB37 pin 33. I have not verified this from a functionality standpoint yet. In my installation, the SL70 port referenced above is currently being used to provide altitude data to my MX20 - so I have a couple of if scenarios.....: If the baud rate on the SL70 port is currently at 9600 and if my MX20 ignores the extended stuff and parses out just the altitude, I'm OK by simply forking the serial output to both the MX20 and the ADS600B. Otherwise, if the MX20 is version 5.6 or later, it should take altitude data along with the Lat/Long it is already receiving from the 420W and freeing up the port for dedicated communication with the ADS600B. I prefer the latter - but I'll take whatever I can get! Hope this helps - and thanks again to the NavWorx crew!

Press ident again to set into the memory if the setting was changed, if not proceed 4. Turn the small knob one click to set the baud rate a. To select and change the baud rate, press the ident button once, the baud rate field will start to flash b. To interface with the Navworx unit, at present, the baud rate will need to be set to 9,600 c. Turn the small knob until 9600 in displayed and press the ident button again to set into memory 5. Here is what is missing from the manual Turn the small knob clockwise one click to the next input screen a. The next screen is the TX screen The TX is for the message transmit format used on the serial port b. There are two options Standard STD and Extended EXT c. Press the ident button to highlight the field. It will start to flash d. Turn the small knob to set the EXT into the field e. Press the ident button again to set the field 6. Cycle the SL70 power off and turn back on. The SL70 is good to go and should now be set up to control the Navworx unit a. Using the maintenance port on the Navworx, set the Input screen to SL70 and DB37 pin 33. I have not verified this from a functionality standpoint yet. In my installation, the SL70 port referenced above is currently being used to provide altitude data to my MX20 - so I have a couple of if scenarios.....: If the baud rate on the SL70 port is currently at 9600 and if my MX20 ignores the extended stuff and parses out just the altitude, I'm OK by simply forking the serial output to both the MX20 and the ADS600B. Otherwise, if the MX20 is version 5.6 or later, it should take altitude data along with the Lat/Long it is already receiving from the 420W and freeing up the port for dedicated communication with the ADS600B. I prefer the latter - but I'll take whatever I can get! Hope this helps - and thanks again to the NavWorx crew!
