10.1. COM Serial
All serial ports of the ip.buffer include full auto-pin detection, auto-baud
rate
measurement, and auto-parity detection. You can also set the type of hardware flow
control for receive and transmit.
10.1.1. Settings
Serial
Autobaud
Whether Scannex auto-baud and auto-protocol detection is
enabled.
[Enabled]
Baud
The baud rate, from 300 to 115200. If autobaud is enabled, this is
the starting baud rate.
[115200]
Protocol
The number of data bits and parity.
[8N]
Rx/Tx
“
DTE: Rx2/Tx3
” – pin 2 is receive on the DB9 connector
“
DCE: Rx3/Tx2
” – pin 3 is receive on the DB9 connector
“
Auto
” – uses the detect voltage on the pin
“
Diagnostics
” – puts the COM port in a diag mode
[Auto]
Rx Flow
Which control lines to use to stop the device sending more data.
[RTS]
1
The NetBuffer and ModemBuffer required a pause in the data after measuring the baud rate and
before detecting the parity. The ip.buffer uses a different technique which means that a pause is
not required.
2
If the device has TTL outputs, and not standard RS232 +ve/-ve signals, you cannot use Auto. The
electronics require the receive pin to go negative to detect.
3
No data can be received in the Diagnostics mode. It reports a “
Detect
” number that can be
reported to Scannex for problem solving.
