RS-232 Parameters - 1
User’s Guide 5-71
The RS-232 Parameters - 1 Programming mode contains
four shortcuts: A, B, C, and D. After entering this
programming mode you can go directly to a specific
parameter by scanning the appropriate shortcut Hex tag
(Hex A through Hex D). This eliminates the need to
enter all parameters when only one needs changing.
