I am wiring up the D100 and D120 and trying to plan the installation of the wiring for the SL30 and the 496, the included Steinair D100 harness has the 3 connector DB9 for PC update and an additional yellow/green wire for GPS/SL30 TX input, I assume this wire is ganged on pin 22 for SL30 nav data RS 232 input from pin 5 (TxD1) on the SL30, is this correct?
Also as this wire has to be disconnected for firmware updates it suggests I need a switch or connector in this line, is this what most people do? The same pin 22 appears to also connect through the null modem to pin 11 of the EMS (I assume TX to RX for pins 2 and 3 in the DB9 connectors via the null modem) and the instructions have the 496 connected to pin 19 on the EMS which is the aux serial receive. Does this imply that all 496, EMS and SL30 communication comes through pin 22 on the EFIS
If I understand this all correctly, to get full functionality I will need to connect the RS232 TX/RX lines and the DSAB A/B lines between the EFIS and EMS, is this correct? Which functions transfer between the EFIS and EMS through which communication path
Sorry for the lengthy post but I am trying to get the picture before I run wires.
