APPENDIX I – COMMUNICATION AND CONNECTION TUTORIAL
There is only one, really basic set of rules that you must consider when wiring two 9760 communication devices together. Those rules are given in item 3 below.
Frustration arises only if the information you are given does not enable you to identify those elements of the connection you need to know or if the information you need is not readily at hand.
You should not be satisfied to just plug in a cable “type” because you are told to without having the slightest idea what to do if it doesn’t work. It’s easy enough to check the parameters for your- self so that when you do plug that cable in, you expect it to work. In fact, you should be surprised if it doesn’t work.
You will never get in trouble when wiring two 9760 communica- tion devices together, if you know and follow the information contained in the following points. You may not always need all the information in all the points, but you must always have enough information at your disposal to follow the connection rules stated in 3.
1.You should always know or be given the location of Pin 1 on each of the devices input/output, plugs/connectors that you intend to wire together.
2.You should always be given the signal function that can be accessed at the Pin 1 location.
3.All communication devices in the 9760 System must be wired so that the result, if checked against the following table, is true.
Device A ➞ | Device B |

would physically be connected to pin 1 on device 2. Straight cable is used in devices where the signal pin run on the first device is opposite that of the second device.
If a cable is “reverse”, then pin 1 on one end of the cable goes to pin 8 at the opposite end of the cable. If the connecting plugs on this cable interfaced separate devices, then pin 1 on device 1 would physically be connected to pin 8 on device 2. Reverse cable is used in devices where the signal pin run on the first device is the same as that of the second device.
The physical wiring differences for “straight” versus “flipped” come about because of the relationship of the physical orientation of the attached plugs when the cable is created.
Almost all pieces of equipment connected to the
How to identify a “straight” cable apart from a “flipped” one is illustrated in Figure

Identifying Cables
Compared “Color Run” is in Opposite Direction
Given 1 and 2 and knowing 3, you can successfully connect any two communication devices together to make them work. In many cases, a cable is provided. That’s OK. Just check it before you use it.
Depending on the physical geometry of the cable itself, you may also need to know how to determine cable “type” before you can apply the rules above. Most devices in the 9760 family use RJ- 45,
This is rigid cable so, in effect, it has a cable “color” run across its width. This fact is used to determine the cable type as either “straight” (parallel) or “reverse” (flipped).
If a cable is “straight”, then pin 1 at one end of the cable goes to pin 1 at the opposite end of the cable. If the connecting plugs on this cable interfaced separate devices, then pin 1 on device 1
Compared “Color Run” is in Same Direction
