Hmmm...is the BCC02 a 15-15 straight cable? If so then I can whip one up myself instead of paying 20 bucks to a dealer... On 5/26/05, Paul Koning <pkoning at equallogic.com> wrote:

I remember it doesn't. The colour monitor cable, for the VR241, has a 4 pin keyboard connector in the junction box , and 3 pigtails ending in BNCs for the monitor. But the VR201 (mono) monitor has the keyboard connector (4 pin, of course) on the back of the monitor, the CPU-monitor cable just has a DA15 at each end. -tony

Well, I certainly posted one a few years back -- for a universal colour/mono/2-monitor cable. Here it is again... A universal DEC Rainbow video cable ----------------------------------- This cable allows almost all possible monitor combinations to be used with the Rainbow (see below).

You could use other connectors, like RCA phono, but BNC are standard. RJ11 socket, chassis mounting (for LK201 keyboard). Chassis mounting sockets of this type are very hard to find. I ended up making a bracket to clamp a PCB-mounting one to the panel Metal box of a suitable size to hold the above connectors (apart from the DA15S). 1m cable. At least 4 75 Ohm screened cores and 6 single wires. I used a 'unversal SCART cable' which has 6 75 ohm screened cores (I simply ignored 2 of them), a 4 way screened cable (I used this for the 4 keyboard connections) and 4 other wires (2 in parallel for each of Power 12V and Power Gnd). Possible monitor combinations : ------------------------------- 1) VR201 only This is pretty useless, but you can connect a VR201 mono monitor using the DEC lead to the DA15P on the box. Connect the LK201 keyboard to either the VR201 or the RJ11 on the box. 2) Standard composite mono monitor Connect monitor input to 'mono' BNC on the box. Connect LK201 to the RJ11 on the box. This works just like a VR201, but you can use any monitor 3) VR201 and separate mono graphics monitor Connect VR201 to DA15P. Connect LK201to either RJ11 on the box or to VR201. Connect second (composite) monitor to the 'green' BNC. You can use the dual monitor driver for GSX and have text on the VR201 and graphics on the second monitor 4) Two composite mono monitors Connect one to 'mono' BNC, other to 'green' BNC. Connect LK201 to RJ11 on box. Using the dual monitor driver, you get text on the first monitor and graphics on the second monitor 5) RGB (sync-on-green) colour monitor (e.g. VR241) Connect monitor inputs to BNCs as follows : Red - Red Green - Mono Blue - Blue. Connect LK201 to RJ11 on box. This gives the standard DEC color monitor connections giving green text and colour graphics using the colour monitor driver 6) RGB monitor and VR201 Connect VR201 to DA15P on box. Connect LK201 to RJ11 on box. Connect color monitor as follows Red - Red Green - Green Blue - Blue This gives separate text and colour graphics displays when used with the dual monitor driver 7) RGB monitor and composite mono monitor Connect mono monitor input to 'mono' BNC. Connect LK201 to RJ11. Connect colour monitor as follows Red - Red Green - Green Blue - Blue This gives separate text and colour graphics displays when used with the dual monitor driver -tony

Yes, but you really want to use 75 Ohm coax for the video signal. You also don't need to wire all the pins. Accordign to my VR201 schematic, the pins used are : 4,5,6 Ground (and shield of the coax) 7,8 +12V (power for the monitor and keyboard) 12 : Composite video 13 : Ground 14 : Data from keyboard 15 : Data to keyboard Keyboard data is at RS232-ish levels, the power is fused inside the monitor at 2.5A, but the keyboard is fed on the CPU side of this fuse. So make sure you use think enough wire! -tony

It doesn't matter if the data wire is heavier than it needs to be, and only having one such cable might be easier to manage. Since heat shrink isn't particularly flexible, something I like to use is the spiral-slit cable wrap. I picked up a reel of it a few years ago and only use a few feet at a time. -ethan
