5: Function Reference
jumper can be identified because it is the only three-prong jumper on the Main CPU card,
and is labelled “J3”.
Units are shipped to the customer with no jumper installed. The jumper is used by
Symmetricom technicians to test and configure the unit. With this jumper installed, the
operation and integrity of the XL-GPS are compromised.
Warning: Do not run the XL-GPS with the jumper, unless specifically directed to
do so by a qualified Symmetricom technician.
To test the state of the factory mode jumper:
F100<S>J<CR>
where:
F
= ASCII character F
100
= unit function number
<S>
= space
J
= specify User Name command
<CR>
= input line terminator
XL-GPS responds:
F100 J FACTORY MODE = 1<CR><LF>
or
F100 J FACTORY MODE = 0<CR><LF>
F100 K I L L – Reboot
Use function F100 K I L L to reboot the unit. Use F100 K I L L after upgrading the system
firmware.
K I L L is a case-sensitive command. When entering this command, use all capital letters
and put spaces between each letter.
To reboot the unit, enter:
F100 K<S>I<S>L<S>L<CR>
For example:
F100 K I L L<CR>
