Appendix E. Strap Codes - Comtech EF Data DMD50 Installation And Operation Manual

E.1 Strap Codes
The Strap Code is a quick set key that sets many of the modem parameters. For quick setup of
the modem, Strap Codes are very helpful. When a Strap Code is entered, the modem is
automatically configured for the code's corresponding data rate, overhead, code rate, framing,
scrambler type and modulation. An example of how to set a strap code follows:
Example: At the Front Panel <Modulator> Menu, depress '↓', then move '→' to the 'Strap
Code' Submenu and enter #16. The modem will be automatically configured to the parameters
shown below in the highlighted row 'Strap Code 16'.
Use the Strap Code Guide (Table D-1) for available strap codes.
