Subject: Wiring Color Codes From: "David Scribner" <david@blackiris.com <mailto:david@blackiris.com>> Date: Wed, 19 Jan 2000 07:18:30 -0600 Since Richard Schneider mentioned in his post the importance of following the correct Color Codes when doing wiring I have posted to the Resources page on the list's web site: <http://diyapason.pipechat.org> , copies of the Color Codes for 50 pair (100 wire) cables. There are two versions, an Adobe PDF document, which requires Adobe Acrobat Reader and a MS Excel spreadsheet. Most people do not use cables larger than these 50 pair ones however, cables do exist in 100 pair and even 200 pair versions. Unfortunately, I don't have the definitive code for the various bundles in these larger cables so those are not covered in the files. If anyone has the exact order for the bundles in larger cables, please let me know and I will update these charts. Having dealt with wiring that has not been done to the color codes, I know that it can be a real mess trying to figure out what is what. To save yourself and others a lot of aggravation ALWAYS use the correct color codes when doing your wiring. It may take a little bit longer at the beginning, especially if you don't have the codes memorized, but those few minutes will save lots of time if at some point you need to figure out a problem and end up having to "ring out" each and every wire to find it.

In addition to David's fine info, it should be noted that the Chart as shown is also applicable for cable sizes *smaller* than 50-pair. Our firm commonly uses cable in 2, 3, 12, 25, and 50 pr sizes -- in each case just follow the code chart from #1 until you run out of wires! Thanks, David, for providing the Charts!

Many companies sell connector that are designed for use with 50-wire (25-pair) telephone cable. Many of these let you "punch down" the wire onto the connector, which therefore has "insulation displacement connection" points that both strip the insulation and grip the copper conductors. For telephonic use, the 50-position connectors are a good match, but for organic use, it is often convenient to use 64-position (32-pair) cable.

These are a plastic shell idc version of the "57 Series" = Telco connector. Newark carries them. Before you go to the expense of buying 32 pair wire and trouble of wiring the connectors, consider that you could buy a pre made 15' cable with 50 = pin connectors on each end for $10 to $15 (I paid $10.80 in quantity 20). The unit manual chests on my Wurlitzer are diatonic and have two bottom boards for each rank. I cut a cable as necessary for each bottom board and wrote the extra wire off as "spares" in case of a problem in the future. = The other end of the cable was hooked to the punch down blocks at the relay. Now I have a male connector on each bottom board and an associated female connector on the relay. Add one more cable of the appropriate length = between these two and the job is done for a total of $32.40 per rank (if you have 15' from chest to relay, longer cables are available). If I change the installation in the future, I change only the connector cables ( and = winding and....... :<) ) Hope this helps, Joe

There are actually quite a large number of sizes available from the 1 pair up to 500 pair! The common sizes that we keep running spools of in stock for our work are in the following sizes: 3 Pair (for diatonically split offset basses) 6 Pair (for chromatic octaves) 12 Pair (for 2 octaves of whatever -sometimes good for stop action wiring) 16 Pair (great for Pedalboards!) 25 Pair (great for 49 note ranks, such as celestes) 32 Pair (great for 61 Note Primaries or chests) 50 Pair (great for "extended" ranks of 73, 85 or 97 notes, although in the smaller groupings, that results in a *LOT* of spares!) The larger sizes beyond this don't have quite as frequent of application as in former times, in that they were usually used to make up the main cables between consoles and the organ proper. Nowadays, much of this is done by either fiber-optic or other forms of multiplexing the signals, rather than huge "analog" cables! Faithfully, "Arp in the Corn Patch" Richard Schneider

You sure about the # count in each bundle? My experience has been with TELCO cables that if there were 64 wires, the first bundle consisted of 25 pair (50 wires) and had the Blue and White plastic lacing around them, with the remaining 14 in an Orange and White plastic lacing. I'm not disputing what you said, but it makes me wonder if they had that cable made up "special"? I use 32 Pair (64 wire) cable by the spool and mine all comes the way I describe, although I purchase mine from Clifford of Vermont, instead of OSI. > In a way, it is too bad they didn't use the resistor color code, but the > telephone industry seems to have a history all of its own!

Subject: telco wiring junctions From: "Brian Graham" <bgraham@geaf.com <mailto:bgraham@geaf.com>> Date: Thu, 20 Jan 2000 13:46:52 -0600 I've been surfing the net looking for telco wiring hardware suitable for organ use. It's been rather frustrating. There are a lot of sites, but they aren't very user friendly, and most of them seem very "data" oriented. Here is what I want: I have for "primary sets" (2 chests, both duplex). For each of these I want to wire each magnet individually to a junction block of some sort on the primary set with a modular plug to which I could connect a cord to from this junction to the console, so that the next time I move it will be less nightmarish. I presume I'll be using 50 pr. cable in order to find standard plugs, since the 32 pr. stuff isn't very standard. Q. Where could I find standard junctions/plugs for 50 pr. cable? Q. Is there a company that would send me a catalog with photographs of this stuff? Q. If I want to use modular plugs, could I buy plugs that I could "splice" to the ends of bulk cable, or will I have to order cable with integrals plugs. Thanks!

The standard plug for a 50 pair cable is two 25 pair plugs (generally referred to as BLUE RIBBON, TELCO, OR CENTRONICS style. Don't know what the official name is). > > Q.

PANDUIT has a good catalog in PDF on their site. Of course you'll have to go through a distributer to actually buy it.

This is probably the most enconmical solution in my experience. > Q. Where could I find standard junctions/plugs > for 50 pr. cable? You should consider buying premade cables, cutting them into two pieces wiring one end to the chest , and the other end to the console. Then you = use one more cable of an appropriate length to connect the two. Newark Electronics sell premade cables mfg by AT&T, and you can also find them at Alltel Supply, and Graybar. I was able to purchase cables with a male end, and a female end 15' in length for $10.80 ea. in 20 quantity. This is less than the Cinch connectors alone from Newark. > Q.

You can buy cables with a plug on one end, but angin, the cable with two plugs is less expensive. Hope this helps. Regards, Joe
