3.3 Serial Type
The BF-480 support three serial types: RS232, RS422 and RS485, These types are listed in the
drop-down menu for the Serial Type setting. Each setup screen and available features will differ
depending on what kind of Serial Types you select and BF-480 product model you buy. Default is
RS232
RS232/422
Baud Rate: default
19200
, range 1200bps to 230.4Kbps, Others
If no suitable Baud Rate in the drop-down menu chose others, input the value you want.
Data Bits
: 5, 6, 7,
8
(default)
Parity Check
:
None
(default), even, odd, mark, space
Stop Bits
:
1
(default), 2
Flow Control
:
None
(default), CTS/RTS (or Hardware), XON/XOFF (or Software)
Force Packet Transmit Time (ms)
: default
20
, range
0
to
65535
The timing of transmitting an Ethernet packet, in order to get the whole data in on packet,
you can tune this setting value to fit the data length of your device per transmission. The
more small value be set will get more less data in one packet.
Delimiter 1(00 to FF)
: default 0x00
Delimiter 2(00 to FF)
: default 0x00
Once receive delimiter 1 or both delimiters through its serial port, BF-450(M)/430/431
immediately packs all data currently in buffer and send it to Ethernet port.
Force Packet Transmit Length (bytes): default
0
, range
0
to
65535
The length of transmitting an Ethernet packet, in order to get a fix length data in on packet,
you can tune this setting value to fit the data length of your device per transmission.
RS485 Only
RS485 Transmission Delay Time (ms)
: default
0
, range
0
to
65535
Due to different device has different capability in handling data received from serial port. So
you can tune this setting value to slow down the speed of BF-450(M)/BF-430/431 to fit the
speed of your device handling.
