I'm in the process of removing the six pack and vacuum system from my RV-8A and replacing it with a D-100 and HS-34. The avionics are an SL-30 and a GX-65, although I realize the GX-65 is apparently not yet compatible. No worries, I'll wait.
I am in the process of wiring everything up to the D-100 and remote compass/OAT and all is working fine. Am awaiting the HS-34 shipment. I'll address HS-34 questions in a moment but have these two questions right now about just installing the D-100 without the HS-34:
1. The install instructions specify that pin 22 of the D-100 is used for both uploading software from a PC and receiving serial data from an SL-30. Do you have to physically break the connection between the SL-30 and pin 22 to upload software or can you just turn the SL-30 off? In other words, can't the SL-30 and a PC both be connected to pin 22 all the time as long as the SL-30 is switched off when the PC is uploading software?
2. Regarding serial ports, my understanding (minimal) is that a transmit port of one device is connected to a receive port of another device. If that is correct, I don't understand the diagram on page 2-2 of the EFIS-D100 Installation Guide dated July 7, 2007. As an example, it shows pin 2 of the PC as serial 1 tx and it is connected to pin 10 of the D-100 which is also called serial 1 tx. Ditto with receive. Pin 3 of the PC is called serial 1 rx and it is connected to pin 22 of the D-100 which is also called serial 1 rx. On the following page the D-100 pins (10 and 22) appear to be properly described as I understand how they are supposed to work. Is there a typo on the PC plug nomenclature for pins 2 and 3 on page 2-2?
As to the HS-34:
1. My SL-30 and GX-65 are wired to an MD-200 ILS head through a switching relay. The SL-30 is set to RESOLVER. I do not intend to change any of that but to simply use the SL-30 and GX-65 serial ports to send nav information to the D-100 HSI. Question: For that configuration it appears that I will not need the HS-34 lower plug at all. Is that correct?
2. The HS-34 lower plug refers to ARINC 429 data. I have not heard of this relative to the SL-30 and the GX-65. Is ARINC 429 involved with these two radios?
3. Back to pin 22 on the D-100. Serial input data to pin 22 is required for the HSI nav display when the HS-34 is not used. However, when the HS-34 is used, it appears that there is no output from the HS-34 to pin 22 of the D-100. Since I intend to have both SL-30 and GX-65 serial data sent to the HS-34 and then on to the D-100 for display, how does it get there? Is that what the DSAB does?
All for now, but I will have more!!
