Charts and Diagrams

Figure C-1 shows the hole pattern for the mounting bracket. Use a 4-40
machine screw, a 4-25 tapping screw, or a 0.125 DIA rivet to fasten the
bracket. A flat washer is not required because the bracket is made of
hardened steel, but a lock washer is required.

Figure C-2 shows the modem connector pinout configuration. A straight
cable is required between the DTE (computer or terminal) and the DCE
(modem).
