ID-1 Ethernet Port
|
Hi,
I've 4 ID-1's. Three of them behave perfectly fine in all respects including DD mode. The 4th however doesn't get recognised by any of the machines I have and they all refuse to acknowledge that anything is plugged into their ethernet ports. Has anyone come across this before or am I doing something monumentally stupid? This ID-1 has been back to ICOM already and they say it's fine (I'll be ringing them again this morning to check exactly how they tested it). Regards de John EI7IG |

Check the female-to-female "RJ45" 8-pin modular coupler. It may not be a true CAT5 "straight through" coupler that's used for CAT5 network cables (Pin 1 on one side appears as Pin 1 on the other side), but a phone company style "rolled pins" (Pin 1 on one side becomes Pin 8 on the other) type of coupler.
Non-network/non-technical persons would switch the names around -- because if you put a VOM trace on one side of a flat piece of 8-wire satin wire to the other side, you would call that "straight through". But, if you put a pair of 8-pin module connectors properly on it, and you study it, you'ld see that Pin 1on one side becomes Pin 8 on the other -- where the wire pairs are "rolled". Try swapping the beige plastic coupler between radios and see if the problem follows the coupler. If it does, go to Radio Shack or Home Depot and LOOK CAREFULLY at the couplers in the blister packs. Study it for straight-through versus rolled. Ron Hashiro, AH6RH Honolulu, HI |

Eyeballed the RJ-45 this morning and noticed some of the plastic between the pins was slightly bent, straightened it up and then the ethernet port is being recognised. Radio was receiving from Ethernet Port and sending data over RF. However data directed at it's IP address wasn't making it out the ethernet port (looking at it using tcpdump). Re-crimped the RJ-45 and still the same issue. So to discount the cable/RJ-45 being faulty. I think I'm going to swap that little pigtail with one from another radio (that I know works), as I have access to more than two radios. Regards de John EI7IG |

After we removed the original RJ-45 and re-crimped all is now working as it should.

For everyone's information. We had one fellow, who just could not make his ID-1 work. Probably spent 8 hours trying different settings, etc. He tried everything, except a different Cat 5 cable. I assume everyone can guess as to the source of the problem. ? Buddy Morgan WB4OMG KJ4ACN Trustee Lakeland, FL USA On May 10, 2010, at 7:30:03 AM, "John Ronan" wrote:
