Look at this: https://forum.unitronics.com/topic/6309-6-pin-rj45-screwed-terminal/#comment-25515 I use these, mainly for testing purposes, but mostly make up a cable using the 6P6C like Kratmel has shown. cheers, Aus -
Saragani, somewhere nearby (next to it?) you should say it can't be edited. Having a number without further info will be just as puzzling.

PS to the FYI, take super care putting the I/O PCB back in. It's really easy to misalign the pins and bend things. Poop! With the I/O on a fair angle to the main board so that you can easily see things, engage the "outermost" pair first and that guides things much better.

Shentek must have changed because mine is definitely a Prolific. But old! I don't have it on hand at present to give numbers etc. Also, have a read of this: https://forum.unitronics.com/topic/6708-jazz-usb-to-serial-converter/?do=findComment&comment=27303 I'd try the battery first, though. Also just ensuring that you have all comms parameters set correctly. And here's something interesting. I went into my U90 install to check how to set things, and opening advanced in the comms box everything fell over. As in serious issue restart needed. This has never happened before. I can't help but think it is related to this problem which I still haven't had time to pursue: https://forum.unitronics.com/topic/8660-v1040-lost-gsm-modem-connection-after-os-update/?do=findComment&comment=36456 So I'm wondering what driver your adapter is using? Even though you are using XP, wondering whether it put a later driver in, and this might be the issue. But I still think Prolific is the main key. And FYI, the battery is a CR 2450 and is awkward to get to. It's under the board. Easiest access is to NOT push the locking tabs in on the back, but use a small flathead to "flare" the edge of the main panel that the locking tab engages on, ease the tab out a bit then do it to the other 3. Remove boards, and remove the display connector to get the last one out. cheers, Aus
