[Jazz and GPRS router MODBUS rs232]

I'm using JZ-PRG, and after connecting pins like on attached picture i got "2" as status massage on SI66 (illegal data address).

Maybe communication it's working, and I just need to adjust parameters for modus

commands?

Thanks

[Jazz and GPRS router MODBUS rs232]

Hi all,

I have problem connecting to GPRS router, maybe problem is in cable or software a don't know.

I successfully configured GPRS communication with routers and configured them to work as MODBUS slave.( One remote unit configured as modbus slave (modbus address 1) which have some inputs for analog signals and other unit next to Jazz which only works as a router).

I tried "modbus poll" program to test communication with routers on PC and found that my data is located on modbus address 30003.

Now the problem is connecting to Jazz.

Configuration of modbus is similar to one from example except that I used timeout time 700 instead of 100

For modbus commands settings are:

SI 141 #1

SI142 #0 ???

SI 143 #10

SI 144 #3

SI 145 #5

SI 140 #604 or # 609

And for cable connection pinout is:

Jazz MJ1022-CS10 Router

7 RTS ----------- 1 DCD ????

3 Tx ----- ----- 2 RD

2 Rx ----- ----- 3 TD

----- ----- 4 DTR

5 Gnd ----- ----- 5 GND

4 DTR ----- ----- 6 DSR

----- ----- 7 RTS

----- ----- 8 CTS

----- ----- 9 RI

Thanks

Best regards
