EDM 01-18 DAG 4.5G2/G4/GF Card User Guide
Type 16 Record
The TYPE_DSM_COLOR_ETH record is shown below:
Byte 3
Byte 2
Byte 1
Byte 0
timestamp
timestamp
type 16
flags
rlen
color wlen
offset pad
(rlen - 18) bytes of record
The TYPE_16 color field is divided into several bit fields as shown below:
Bits
Attribute
0-5 Receive
stream
0-63
6-13
Filter match bits (bit 6 = filter 0, bit 7 = filter 1 etc)
14
hlb0 (CRC calculation) output bit
15
hlb1 (parity calculation) output bit
Note:
Because both the Type-2 and Type-16 Ethernet record header
occupies 18 bytes instead of the standard 16 bytes, any payload
captured will always be 2 bytes less than the slen value ie. a slen of 48
which will produce a 64 bit record made up of 18 bytes of header and
46 bytes of payload.
Because the slen value must always be a multiple of 8, this means that
if you wish to capture 48 bytes of payload for instance, the slen must be
to set to 56.
