P774 data bits
The number of data bits per character for the selected port, ports 1 to 3 (P774-01 to –
03).
Protocol P774 Value
Modbus RTU 8
Modbus ASCII 7 or 8
Dolphin Plus 7 or 8
Note:
If using port 2, 8 data bits must be used.
Values
5 to 8 ( f =8)
P775 stop bits
The number of bits between the data bits for the selected port, ports 1 to 3 (P775-01
to –03).
Values
1 or 2 ( f =1)
P778 modem attached
Sets port 1 (P778-01) to use an external modem.
Any connected modem must be set up to auto-answer incoming calls. The BW500
does not automatically configure the modem.
Autobaud (enabled by P778=1)
When the BW500 is powered up or the P779 Modem Inactivity Timeout expires three
carriage returns are sent to the modem to allow it to set its serial connection to P772
Baud Rate.
If a connection is made with the modem at a different baud rate the BW500 will
attempt to use that rate instead of the P772 value. For troubleshooting purposes the
baud rate on the modem can be hard-coded to the rate set on the BW500. See your
modem documentation for information on fixing the baud rate.
Values
0 * No modem connected
1 Modem connected
P779 modem idle time
Sets the time in seconds that the BW500 will keep the modem connected even
though no activity is happening.
To use this parameter ensure that P778=1.
