Most entries on this page are self-explanatory. The following lists unique or important parameters.
• Fill in the date and time fields as soon as practical. Events are captured with time/date stamps,
which is valuable information for troubleshooting.
• Set the Link Security Key to something other than the factory default setting (12 characters, all
zeros) at each end. The link security key must match at both sides of the link. If the security key
remains at the factory setting, the radio link is open to sabotage by a party with the same radio
model. Each link should have a unique security key. If using the same security key for every link
in the network, the radio could link to any other radio with the same security key. This is
problematic in multi-radio networks.
– Note that the security key must be exactly 12 characters. Any alphanumeric character can be
used. The link security key is case sensitive.
• Reset the admin and user passwords. These passwords should not match. If the admin password
remains at the factory default setting, it provides an opportunity for random reassignment by a
network-connected user.
– The new password must be entered twice. If the passwords do not match and the Update
button clicked, the password is not changed and remains set to the previous password.
• Enter the license key provided by Exalt to access extended features or diagnostic capabilities.
Click Update to accept the changes and enable the new features. License keys are issued by radio
serial number, so ensure that the license key used was issued for this particular radio.
• The Regulatory Domain Key establishes the frequency bands, tuning frequencies, bandwidths,
output power and Dynamic Frequency Selection (DFS) requirements, in accordance with the
regulations that apply in the country where the product is deployed. The RDK must be typed in to
enable ANY functionality for the radio. The RDK is issued to the Exalt Authorized distributor or
reseller, and is paired to the specific serial number of the radio.
• AES (Advance Encryption Standard) can be implemented to provide additional data security for
the wireless link. This function requires an upgrade license key (purchased separately). Both
radios in the link must have a valid AES upgrade license key to implement AES. Different bit-
length encryption license keys (for example, 128-bit and 256-bit) are also available, depending on
model type. If the required upgrade license key is present, simply insert a matching hexadecimal
string on both terminals and select the Enable AES On option for AES encryption. Note that
similar to the administration and user passwords, the AES string must be entered twice for each
terminal.
Note: Changing the link security key interrupts transmission until the opposite end is
changed to match. Always change the far-end radio first, and then change the near-end radio.
