Newbie here, "Hello"

In HDLC Mode protocol disconnect from meter looks something like this:

HDLC Flag: 7E Frame format: A0 Frame length: 07 Dest and Source addresses: 0303 Control field: 53 HCS: 80D7
HDLC Info.: FCS: Flag: 7E
SEND: 7E A0 07 03 03 53 80 D7 7E
RECV: 7E A0 20 03 03 73 F0 2E 81 80 14 05 02 00 F8 06
RECV: 02 00 F8 07 04 00 00 00 01 08 04 00 00 00 01 58
RECV: 71 7E

How do you protocol disconnect in IP mode from meter? (not TCP disconnect)

Hi Fred,

You need to call release to close the connection in WRAPPER mode.
You need to call client.release.

Thanks Mikko,

What would the byte structure look like for the above example, with Dest and Source addresses: 0303?

Hi,

Destination and source addresses are 1 and 1, not 3.
WRAPPER looks like this:

00 01 00 01 00 01 00 05 63 03 80 01 00
