SEL-3044 Encryption Card
Overview
The SEL-3044 Encryption Card is a standalone card that can be added to the SEL-3031
to encrypt the radio data being sent between SEL-3031 radio links. The SEL-3044 can
be ordered at time of purchase or added as an upgrade. The SEL-3044 requires one
setting to provide a very strong level of encryption over the radio link. Anytime the
SEL-3031 is used with critical data it is strongly advised to use the SEL-3044. If you
do not use the SEL-3044, the data between the radios can be compromised. If you want
to encrypt the radio link an SEL-3044 is required in both radios.
NOTE: The SEL-3044 is NOT a PCMCIA card. Do not install
in a laptop.
