  1. Hi, I managed to pick up another Linebacker to keep on the bench for testing (I'm messing around with Arduinos, Artnet, E1.31 and DMX at the moment)... this time a faulty one, the reported fault was that the display didn't work. Turns out the power supply was u/s! Replacing the power supply has brought it back to life but not 100% (the display just displayed two slightly faded bars). The battery (a Ni-MH one) has seen better days and is now rather fluffy and leaky :-( I've removed the battery and have a replacement on order. Unfortunately this has done some damage to the PCB beneath. Nothing too major, just one track that had been eaten through with some others looking bad but not gone. I've given that part of the board a good clean with IPA and have repaired the broken track by tracing it through and using carefully soldered wire wrap wire. It's now mostly working. The display appears to need replacing as it's fading in places but that's a cheap and easy fix. DMX in and out appear to be working as expected. The main problem is that the cable test doesn't function properly. If I disconnect the input and output boards (the ones attached to the XLR connectors), it'll report 'multiple cable faults'. If I reconnect the boards, it reports 'no cable'. However, when I try it with a known good cable or even a cable with 2 & 3 swapped (I've got some old Martin gear that needs it), it goes to 'Starting DC test' and that's where it sits. Not sure whether this could be caused by another faulty track or maybe something else. This is a unit from 2000 and the board is issue 4, revision 2. It's running version 2.0 of the firmware (9504). The only other thing to note is that this one's got a PALCE16V8H-15 labelled 9602 whereas my older one (issue 2, version 2 board which stays with the gear I take out) has got a PAL16R4A-2CN labelled 9601. Any help or advice would be appreciated. Many thanks in advance, Neil.
  2. Paul, many thanks for answering my questions so quickly! I'll grab the HEX files and get a new EPROM written - what EPROM should I use? The part no. is covered on the current one and I'd rather not rip the label off to check it! Is it a 27C256? It'll be 2.0 as the cable tester definitely works and was one of the reasons of picking it up! Thankfully it's an older one! As for the batter - I'll get a NiMH one on order! At a glance and without removing the battery it looks like the board is OK. Fingers crossed it is when I get the battery off! Many thanks once again, Neil.
  3. Hi, I've just picked up a linebacker for a sensible price to keep in my toolbox for cable testing and the odd backup job and I've got the following questions: 1. The device reports software version 1.2 and I see the manual that's available for download refers to software version 1.8. Is it possible to update the device? If so, is this available as a replacement EPROM (in which case what would the cost be) or could you supply a .HEX (or equivalent) file so I could get an EPROM programmed myself as I have access to EPROM programmers. 2. The internal backup battery appear to work OK but is looking like it's seen better days (it's starting to look a little fluffy)! It's a Varta 3.6v 110mAh Ni-Cd with the number '105'. I can't find a a replacement, only a NiMH variant but I don't know if that would be a suitable replacement. Any suggested replacement batteries? Apart from those couple of things the Linebaker works perfectly and will come in very handy! Many thanks.
