― Destination RF MAC address. User entered RF MAC address of the Viper unit they wish to connect to (Format
0x00000FD4). Default = 0xFFFFFFFF) Send a broadcast packet to all Viper listening for the test packets.
― Number of packets to transmit. The total number of packets transmitted during the test. Default = 1.
― Delay between packets. The user can enter a delay in milliseconds between the packets being sent. Note: If a delay is
not present between packets, it may appear the transmitter does not unkey and is only sending one long continuous
packet.
― Packet data pattern. Select Fixed/Random Fixed data is highly compressible; random data is not; Viper SC utilizes a
data compression algorithm to compress data before transmitting.
― Packet data type. Select ASCII/Binary. Hex formats. ASCII data is highly compressible. Random Binary data best
simulates PLC SCADA data.
― Length of data payload. Enter the length of the data to be transmitted. Note: A typical SCADA value would be
between 10 to 250 bytes. The maximum value is equal to the MTU set in each Viper SC unit.
― Lock PTT between packets. If the "Off" option is chosen and enough delay has been added between packets, the
Viper SC will stop transmitting between packets. If "On" is selected the Viper SC will continuously transmit between
packets.
― Test Mode. Select Enable/Disable. If Enabled, Viper listens for test packets being transmitted from a remote unit.
Start Test/Stop Test. Click to start/stop transmitting test packets. Test packets received are stored and can be used by
selecting Show Stats. Select Clear Stats to clear test results.
Warning! When Viper is in test mode, it will not respond to RF activity from other Viper units. Test mode cannot be Enabled
(active) for more than 15 minutes. After 15 minutes, test mode will be automatically disabled and normal communications
will resume.
