Long story short I'm adding scope to a 2nd little tin boat i bought. I will be moving the black box and 126sv head unit back n forth between boats. My question being what cables do I have to order? It's been several years since I hooked up my livescope and forgot what I all need. I need a black box power cable and 126sv power cable. The transducer cable plugs into the black box. Then I need a black box network cable to a 126sv network cable???? The last one is where I'm fuzzy. Can anyone help. Isn't the black box network cable and 126sv network 2 different cables that attach to each other? Thanks in advance.
