Amount of protocol dump data in
one protocol dump list print
operation
0: Up to the limit of the memory
area for protocol dumping
1: Last communication only
Change this bit to 1 if you want to have a
protocol dump list of the last communication
only.
How to calculate the RX level listed on the Journal (when bit 2 of system switch 00
is set to 1)
Example: 32 V34 288 L 01 00 00 00
The four-digit hexadecimal value (N) after L indicates the RX level.
The high byte is given first, followed by the low byte. Divide the decimal value of N
by -16 to get the RX level.
In this above example, the decimal value of N (=0100[H]) is 256.
So, the actual RX level is 256/-16 = -16 dB.
