NV3128 RS-422A Machine Control Data Routing Switch 3-14
Screen II
Editing the scramble map:
1. Function Key F7 allows setting the router level on which the scramble
map is to operate. ESC exits this edit mode.
2. Function key F2 loads the scramble map currently active in the router
controller RAM.
3. Function Key F3 loads a scramble map previously saved to disk.
4. Function key F8 invokes the scramble map editor.
5. Function key F4 downloads the edited scramble map, along with the
configurationinformation entered in screen I, to the router.
6. Function key F5 loads the edited scramble map, along with the
configuration information from Screen I, to disk. Prompt is for a file name.
The default file-name extension is .CFG.
· The scramble map operates on up to 256 addresses. The ranges of
addresses available to a given map begin at the points defined in Screen
I.
· Initially, undefined map fields within the configured partition range will
consist of “---” entries. Out of range fields are blank.
· Keyboard arrow keys guide the editor through the fields. The enter key
accepts the keyed in data.
· Two physical inputs can be a mapped to a single input controller
address, and two physical outputs can be mapped to a single output
controller address. This allows pairs of connections to be made with
a single take. However:
Physical input ports may be assigned to multiple controller addresses.
Physical output ports may only assigned to a single controller address.
Because of this restriction, output port entries must be nulled or re-
assigned before they can be re-used. To empty a field, enter a
SpaceBar followed by Enter.
· Some control systems begin their addressing with 0. The NVision
routers begin their physical addressing at 1.
· The ESC key ends the edit session.
