 Local Time
Displays time zone configuration using UTC time and the configured Time Zone. An SNTP
server can be specified under Setup (Advanced) D Time Source. The time will reset to the
default setting if power is cycled on the Viper unit and no SNTP server is configured.
 CWID
Continuous Wave Identification - Default = Disabled
Allows the user to broadcast their FCC call sign.
CWID Call sign is the user's FCC call sign to be broadcast.
CWID Interval is the time interval in minutes that the call sign will be broadcasted.
CWID can be configured under Setup (Basic) D General.
 IP Forwarding Mode
Displays IP forwarding mode (Bridge or Router). The IP Forwarding Mode can be configured
under Setup (Basic) D General D IP Forwarding Mode.
 Station relay point
Displays if the unit is being used as a relay point (Yes or No). The Station Relay Point can be
configured under Setup (Basic) D General D Station relay point.
 Multi-Speed Mode
Displays if a unit is in multi-speed mode (enabled), or not (disabled).
When Multi-Speed mode is disabled (default), the units communicate with each other at a
fixed speed. This data rate is user programmable and must be programmed on each Viper
unit.
Enabling multi-speed mode on a standard Viper will configure the unit to be a rate-follower.
In this mode, the unit will adjust its over-the-air data rate to that of the rate-controller.
The rate-controller feature is not available on the standard Viper unit. It is only available
with the 19’’ rack mount Viper Base Station. With the Viper Base Station, the user can
configure the master Viper(s) to be rate-controllers. The user can then configure the rate-
controller to talk at different over-the-air data rates for each remote Viper. This allows the
user to uniquely control the data rate for each RF link in the system from the Base Station
web pages. The user can program RF links with strong signal strength to communicate at
fast data rates and RF links with low signal strength can be programmed to communicate at
more robust, slower data rates. The data rates chosen must all use the same bandwidth.
In a network operating with Multi-Speed, there will normally be one rate-controller (Viper
Base Station) with all other units configured to operate in rate-follower mode.

ETSI (European Telecommunications Standards Institute)
Displays if the unit is in ETSI Mode (enabled/disabled).
Note: This parameter is not user settable. It is programmed by the factory for European or
Australian/New Zealand approved Viper models.
