Hello guys, do you have experience with communication unit CU-P42 https://www.prodemel.es/manuales/LANDIS_GYR_CU-P4X-datos-tecnicos.pdf connected to Landys+gyr e650? There are some mysterious at commands before data communication. Do you have datasheets for this modem?
Landys+gyr CU-P42
Hi,
We have read CU-P42 for a long time for one of our clients. If I remember right and you are using Map120, there are set some modem settings first. Those are AT commands what are sent.
Post that data here if you need help. Please, do not post all data, just those AT commands.

Mikko
log
I have log from application vdewsrv.exe 3.5.7.11:
Baud:2400 DataBits:7 Parity:Even StopBits:1
Transmit: ATE0V1X3[0D]
Receive: [0D][0A]
Transmit: ATDT732[0D]
Receive: OK[0D][0A][0D][0A]CONNECT[20]2400[0D][0A]
and now iec62056
Transmit: /?![0D][0A]
Receive: /LGZ3\2ZMD4104407.B14[0D][0A]
...
Without right at commands I get damaget some data, look at the first two lines from register:
\x82\xc6.\xc6(00000000\xa9\x8d\n0.0.0(5\xb1\xb29\xb43\xb2\xb4\xa9\x8d\n
Instead [02]F.F(00000000)\r\n i got [82][c6].[c6](00000000[a9][8d]\n

Hi,
ATE0V1X3 is init command. after that you call (ATDT) to number 732.
Are your serial port settings same? Because this might be the problem.
If I remember right you should use 9600 or 4800 8N1.

tcp/ip initialization
I'm doing it all wrong. This AT commands are for dial-up connection, but I use tcp/ip. All what I need to know, is how to make initialization for tpc/ip.
tcp/ip initialization
Hi,
If you are using TCP/IP connection you do nothing. Just give correct port and IP address. Make sure that module is enabled. You can access module with GXDLMSDirector using optical eye or serial port if you change logical server from zero to one.

my data is broken.
Now I do not have access to dlms director, I'll try it later.

Ok I have emeter back and look at this.
If I set protocol IEC + "use serial port through ethernet" dlms director has same issue

what is this? incorrectly adjusted electrometer?
tcp/ip initialization
Hi,
"Use serial port through ethernet" is used if you have TCP/IP to serial port converter. Example Moxa. Do not select that.

Hi,
Hi,
if you meant this strange data(I get them over TCP/IP + IEC):
AF CC 47 5A 35 5C B2 .....
It's because encoding of 7bit with parity. Make logical 'AND' for each character, ex:
'AF' & 0x7F => '2F', and 2F is '/' character you expected.
