FYI, an RJ-8 modular plug will plug right in to an RJ-45 modular jack.... The retention key on the connector centers it in the RJ-45 jack so that the 4 center conductors are lined up.
The key to making this work is to verify: 1) How are the jacks wired on the switch: 568A or 568B. 2) Match up the wiring in and out on the two P3 TxMon couplers' twisted pair jumpers and the patch cable you buy/make/modify to be the common jumper back from the switch to the P3 rear panel. Eesentially, you're making sure Elecraft used straight through wiring and not some sort of crossover arrangement or other between the P3 and the couplers. DON'T plug it all up UNLESS and UNTIL you map the conductors to make SURE they have continuity and continuity in accordance with the wire conductor order used on the P3 and the coupler. PROBABLY, Elecraft used straight through wiring, so it is just a matter of making the additional straight through patch cord to go from the P3 to the switch in/out. IF you want to get fancy and have the tools/skillset, make all new cables... Use RJ-8 on the P3 and couple ends and use RJ-45 on the ends that will plug into the switch. Holler if this has completely confused you and I will amplify/clarify. 73, ______________________ Clay Autery, KY5G MONTAC Enterprises (318) 518-1389 On 6/18/2016 4:36 AM, Mike VE3YF wrote: > Hi Alan: > > Tnx for the info, good to see someone else has done it.
