NOTES
1. Saved configuration data is read at power-up and compared with
configuration jumpers. If the saved configuration data has never been
saved (e.g., new installations) an ERROR 30 Check Configuration will
occur when the box comes out of standby. If the saved configuration data
does not match the current jumper(s) an error 30 will occur at power-up.
The conflicting jumper(s) will be highlighted on configuration screen(s).
(See figure 4-8.)
2. Configuration pages 1, 3 and 4 contain configuration jumper data. On
each page verify jumpers are correct and press SAVE to write the new
configuration into system memory. When done the SAVE button
disappears. Repeat this step for each page. Save command can be used if
using a terminal device.
