Comtech EF Data OM20 - Manual (Page 168)

OM20 Universal Outdoor Modem Appendix B
MN-OM20– Revision 5 B–2
The value displayed on the top line of this menu is the 12-digit Unit ID. It is displayed as 3 sets
of 4 digits in a dot-delineated format as follows:
1 2 3 4 . 1 2 3 4 . 1 2 3 4
Your Comtech EF Data Sales Representative will ask you for this number along with your
desired feature set upgrades when placing your order.
Once your order has been processed, you will be issued a 12-digit feature set upgrade code. This
code is only good on the modem for which it was ordered. To enter this code from the terminal
port, perform the following:
a. From the “Enter Selection Number” line type in 45.
b. Press Enter.
c. Enter the new code and press “Enter”
d. Your system is now up graded.
If the code entered is correct, the display will display CODE ACCEPTED, otherwise the
display will display INVALID CODE.
Care should be taken to insure that the upgrade code is entered properly.
After three unsuccessful attempts to enter a code, the upgrade and
demonstration capability will be locked out and it will be necessary to
cycle power on the modem in order to continue.
