Hello everyone,
First of all, I'm sorry for any mistake I may make, I'm not English.
I've also never worked in electronics.
Here is my situation: I've been told to power a particular device and to transmit its signal to a BNC, without any more information. After some research, I found that I'm gonna have to deal with a 9pin cable. I found two diagrams of this cable:
Firt diagram:
Shield
Pwr Rtn
Power-
Pwr Rtn
Power+
Lock-
Lock+
Sig -
Sig +
Second diagram:
Shield
Gnd
Power-
Gnd
Power+
Gnd
Press+
Sig -
Sig +
Here are a few questions, but feel free to give any advice for newbe:
1) Shield, Power Rtn (Return?), Lock-, and ground all have to be grounded, have they not? Why are they called differently ?
2) How to transmit the signal to a BNC ?
Sig- for the outside of the BNC, Sig + for the inside ? Or should I ground the outside and transmit only sig+ to the inside, and don't use sig- ?
3) What's Press+/Lock+ ? What do I have to do with that ?
I will perhaps think about other questions later;
Thank you for your help!!
