Gateway ID - ADVANCED SETTING - DO NOT CHANGE - Manual overrides of the
NIC’s gateway identifier.
ARP Cache – Disabled by DEFAULT. When enabled, the radio will respond to ARP requests
intended for other network devices with known addresses. It will not forward the ARP to the
intended device.
ADR Mode – Adaptive data rate mode controls whether the NIC will attempt to use different
modem speeds for different remotes. All downstream traffic uses the lowest rate; only
upstream traffic can use the variable rate. ADR setting is automatically learned by remotes, but
remotes modem must be set to Auto, or 125 for 125-250kbps, or 500 for 500-1250 kbps
operation.
- 125-250kbps – ADR will attempt to use the FHSS modems (125kbps and 250kbps) when
trying to determin the best modem for the remote.
- 500-1250kbps – ADR will use the DTS modems (500kbps, 1000kbps, 1000W kbps, and
1250 kbps) when attempting to determine the optimal rate.
- none – ADR is not used and the static modem setting in nx-config is used for the modem.
ADR Threshold – The threshold is an RSSI threshold. If the received signal is stronger than
the threshold the NIC will attempt to use a faster modem. ADR Threshold must be set for each
radio (Remotes and AP). This is advantageous in that you can run the majority of the network
in ADR mode, but if a particular remote has strong RSSI but difficult channel conditions, you
can effectively disable ADR on that specific remote by setting the ADR threshold artificially
low. DEFAULT = -70, range from -127 to 0.
Encryption Protocol – Encryption Protocol 2.0 provides the highest level of over the air
encryption security with a strong encryption key, but is not compatible with MCR-900 radios
running firmware earlier than 3.1.0. Encryption Protocol 1.0 provides compatibility with older
firmware by using the strong key when talking to units with firmware 3.1.0 and later, and a
less strong key when talking to units with firmware earlier than 3.1.0. DEFAULT 2.0. For
