Hi Kalle,
I cannot find DSR and RTS on the balance.
I tried the follwing today:
- Balance to Hyperterminal:
9600 bps, 1 stopbit, 7 databits, hardware control
The balance can do handshake in hardware control or software control, not without. This works, data arrives in the hyperterminal.
- Hyperterminal to CP340 (read with P_RECV)
9600 bps, 1 stopbit, 7 databits, No Hardware control.
When I set No Data Control in Hyperterminal as well, then I can Send data to the connected DB in S7, NDR becomes high every succesful received char.
Balance connected to CP340:
- The RXD led only blinks when I set RS232 automatic under the tab transfer. But I cannot read data Error on P_RCV block, status 818.
hmmm
Do you have an idea ?
thanks
Do you use the BRECV to read out the data?
Edit: And you could try to use No dataflow control, and to strap DTR/DSR and RTS/CTS on the balance side.
