4.4 Upgrading the Modem Feature Set

Each of the modems in the PSM-500 series is available currently with 3 different "Feature Sets",
M505, M511 and M523, representing basic capabilities that suit it to certain tasks. They are
currently given a feature set code representing the elements of those features. Refer to Section
1.1.2. which shows the capabilities of each standard feature set.
Upgrading from one feature set to another is accomplished in the following manner.
Contact your local reseller or Datum Systems directly requesting an upgrade and noting the Unit
Serial Number, current version and the version to which you would like to upgrade to. There are
only 3 upgrades possible at this writing, from the M505 to the M511, from the M511 to the M523
and from the M505 to the M523.
Upon purchasing an upgrade you will be provided with a special 16 digit code which is used to
enable the upgraded features. The code is unique to this unit's serial number and will not work in
any other modem.
To insert the code go to the <Unit: Status - Feature> parameter using the front panel keypad.
Then enter the 16 digits of the given code directly using the digits on the keypad, then press the
"Enter" key. If correctly entered the modem will now display the new feature set and list the
available modulation modes above the standard set in the M505. For example when the M523
feature set is enabled the <Unit: Status - Feature> parameter will display "M523-8PSK-16QAM".
Feature sets can only be upgraded. There is no code to downgrade a feature set to a lower one.
4.4.1 Future Software Options –
In the future we may have additional options which can be enabled via an "unlock code". For
example, newer FEC options based on Intellectual Property (IP) which we must license and
charge for, may fit into this category. The procedure for these options will be similar to that
described above and explained in the transmittal that accompanies the unlock code.
