• Select Packet Headers under Event Groups.
You see the Packet Headers window:
Packet Type
The Packet Type drop down menu lets you select the following packet types
for filtering or triggering: NULL, POLL, FHS, DM1, DH1, HV1, HV2,
HV3/EV3, DV, AUX1/PS, DM3, DH3, EV4, EV5, DM5, or DH5.
Select “Don’t Care” if you want Merlin II to ignore this field.
LT_ADDR
(Logical Transport Address) The LT_ADDR is a three bit slave address. To
select packets from a particular slave device for filtering or triggering, enter
an address into the LT_ADDR text box. You can target up to three devices
using the three text boxes.
SEQN, ARQN, and Flow Control Bits
To set event conditions on SEQN, ARQN, and Flow control, uncheck
"Don't Care." Unchecking "Don't Care" sets the event condition to
SEQN=0 AND ARQN=0 AND Flow=0. This action also puts a checkmark
in the box marked "Packet Headers." A checkmark next to SEQN, ARQN,
or Flow changes the value of this field from zero to one. For example, if
SEQN is checked, the event condition becomes "SEQN=1 AND ARQN=0
AND Flow=0.
