Command Set

dbe_personality – set / get the RDBE FPGA bit code personality

dbe_dot – get the Data Observable Time (DOT) clock information

dbe_dot_set – set the DOT clock on next 1pps tic

dbe_dot_inc – increment the DOT clock

dbe_status – get system status

dbe_sw_version – get the RDBE command/control software version numbers

dbe_ifconfig – set / get RDBE 10G network interface configuration

dbe_arp – set / get the IP to MAC address resolution

dbe_packet – set / get packet transmission criteria

dbe_data_format – set / get data transmission mode

dbe_data_connect – connect an IF to a destination IP address

dbe_data_send – send a valid data stream out of the RDBE on/off

Communication Model Sequence

Step 1: load personality

Step 2: setup 10Gbit communication

Step 3: setup timing

dbe_personality = <type>;

!dbe_personality = <return code>;

dbe_ifconfig = <state>:<mtu>:<mode>:<ip>;

!dbe_ifconfig = <return code>;

dbe_arp = <ip>:<mac>[:<ip>:<mac>];

!dbe_arp = <return code>;

dbe_dot_set = <ho time>;

!dbe_dot_set = <return code>;

dbe_dot_inc = <secs>;

Step 4: setup packet format

Step 5: data transfer

!dbe_data_format = <return code>;

“Station PC” RDBE

dbe_packet = <dp offset>:<df offset>:<length>:<psn mode>:<psn offset>;

!dbe_packet = <return code>;

dbe_data_send = <state>:<start time>[:<stop time>][:<duration delta>];

!dbe_data_send = <return code>;

After stop time or duration elapses issue another . . .

dbe_data_send = <state>:<start time>[:<stop time>][:<duration delta>];
