Hello folks,
I'm working on my harness tonight for the PMA5000 and the SL-40. Looking at the wiring diagrams for the SL-40, I have the Headphone (pin 14) going to COM 1 audio hi (pin 9) on the PMA 5000 and the Audio gnd (pin 13) going to com 1 lo (pin 10) on the 5000. That I get.
Looking at the Mic setup...Mic 1 (pin 8 SL40) goes to com 1 mic audio hi (pin 11 5000). The Mic gnd (pin 7 SL40 doesn't go anywhere on the pma5000, but the SL-40 manual indicates to ties it to the audio gnd (pin 13) which will go to pin 10 on the PMA5000. Those are 2 wire shielded wires.
The problem I'm having is the Txkey is on it's own and not shielded on the SL-40 manual and is supposed to go to the PMA5000 pin 12 com mic key where it is showing as shielded?
So, should I use a 3 wire shielded cable for the mic setup, tie the mic ground to the audio ground and go from there?
I love this stuff!!!!![Roll eyes :rolleyes: :rolleyes:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
