Q32128: Extension Cables for Microsoft Mice
Article: Q32128 Product(s): See article Version(s): 5.x 6.x 1.00 Operating System(s): MS-DOS Keyword(s): ENDUSER | | mspl13_basic Last Modified: 17-JUL-1989 Microsoft retails a 1.5-meter InPort extension cable. Although the cable was designed for the gray-button mouse, we have found, under informal testing, that the extension cable works with the new white-button mice (serial and bus). If you decide to make a longer cable, special wire is not needed. The Microsoft extension cable uses shielded, 7-conductor, 30-gauge wire. A heavier gauge wire might be considered for strength. If an extension is added to the serial mouse, the cable needs to pass the following pins straight through as follows: pins 2,3,4,7,20 and shield for the 25-pin D version, or pins 2,3,4,5,7 and shield if using the 9-pin version. Microsoft is not aware of any special considerations for special installation, such as alignment to compensate for cable characteristics, special cable termination (R, RC, etc.), needed for line drivers, or noise-immunity considerations. If you do anything to change the mouse cabling, the machine is likely to violate FCC Electromagnetic Interference regulations. The computer may interfere with nearby television or radio reception. Operation in a residential environment is especially ill-advised, and such a configuration certainly cannot be offered for sale without extensive testing and FCC certification. Microsoft takes no responsibility for the performance of its products when modified or used in a manner other than that intended and advised in the manual. Microsoft assumes the customer will comply with all applicable laws and regulations, and offers the above advice only on that basis.
