NOTE: For short distances that exceed the cable length supplied, you might consider the use of CAT 5 cable (for distances up to 300 feet). This cable is RS-422 compli- ant (up to the length men- tioned) and is used primarily for Ethernet connections within networks. Moreover, it is readily available (be- cause of demand) and cost is reasonable (because it is less difficult to manufacture).

Most of the time, connection cables are supplied with the device. As long as the supplied cable is appropriate, no problem arises. If the cable length needed is greater than that sup- plied, a problem arises for the installer/specifier as to the type of cable to use. One of the most common hookup extensions is the remote hookup of a 9760 keyboard. The following highlights the issues involved and ends with some recommendations.

For remote installation of a keyboard, the user must supply a cable of appropriate length that supports the TIA/EIA-422-B (RS-422) communication standard. The example in Figure 21 shows a keyboard placed 2,000 feet (610 m) from the CC1 via the user-supplied cable. Junction boxes (phone boxes) are used to facilitate the RJ-45-to-cable connection points at either end of the run. Note that only signal wires and ground are run through the cable itself (five of the six available wires are used in the example). The transformer serves to pass on the data signal and to supply power to the keyboard at the keyboard end.
