  • 2400
  • 4800
  • 9600
  • 19200
     (default)
Data Bits
Specifies the number of bits of data per character. Available options are:
  • 7
  • 8
     (default)
For DF1 Point to Point, DF1 Master, DF1 Slave, DF1 Radio Modem and DH485 protocols,
Data Bits
 is disabled and set to 8.
Parity
Specifies the parity of the transmitted data to verify data integrity. Available options are:
  • Odd
  • Even
  • None
     (default)
Available options for DF1 Point to Point, DF1 Master, DF1 Slave, and DF1 Radio Modem are:
  • None
  • Even
For DH485 protocol,
Parity
 is disabled and set to
Even
.
Stop Bits
Specifies the number of stop bits for each data value sent. Available options are:
  • 1
  • 2
For DF1 Point to Point, DF1 Master, DF1 Slave, DF1 Radio Modem, and DH485 protocols,
Stop Bits
 is disabled and set to 1.
Serial Media
Determines whether the media connected to the channel's serial port is
RS-232C
,
RS-422
,
RS-485
. The default is RS-232C.
Available options for Generic ASCII, Modbus Master, Modbus Slave, DF1 Master and DF1 Slave are:
  • RS-232C
  • RS-422
  • RS-485
Available options for DF1 Point to Point and DF1 Radio Modem are:
  • RS-232C
  • RS-422
Available options for DH485 are:
  • RS-232C
  • RS-485
Duplex
Specifies the handshaking used by channel.
Available options for Generic ASCII, Modbus Master, and Modbus Slave are:
  • No-Handshake
  • Full Duplex
  • Half Duplex
Available options for DF1 Master, and DF1 Radio Modem are:
  • No-Handshake
  • Full Duplex
  • Half Duplex
Available options for DF1 Slave are:
  • No-Handshake
  • Half Duplex
Available options for DF1 Point to Point are:
  • No-Handshake
  • Full Duplex
Available option for DH485 protocol is:
  • No-Handshake
Tip:
Full Duplex
 and
Half Duplex
 are available only when
Serial Media
 is set to
RS-232C
.
Continuous Carrier
Determines whether to transmit a carrier frequency even when no data is sent.
Select the checkbox to use continuous carrier with half duplex communication.
Tip: The checkbox is available only when
Duplex
 is set to
Half Duplex
. In DF1 Master,
Continuous Carrier
 is always cleared and disabled.
RTS Send Delay
Specifies the delay (in 20 msec) between the time the RTS signal turns on (high) and the time data is sent.
Valid value is from 0 through 32767. The default is 0.
Tip: When the serial media is RS-422 or RS-485,
RTS Send Delay
 is disabled and set to blank.
RTS Off Delay
Specifies the delay (in 20 msec) between the time the last character is sent and the time the RTS signal turns off (low).
Valid value is from 0 through 32767. The default is 0.
Tip: When the serial media is RS-422 or RS-485,
RTS Off Delay
 is disabled and set to blank.
DCD Wait Delay
Shows the seconds the data carrier detect (DCD) waits until it becomes inactive before discarding the packet.
Tip:
DCD Wait Delay
 is enabled only for DF1 Radio Modem protocol. For other Serial protocols,
DCD Wait Delay
 is disabled and set to 1 second. When the serial media is RS-422 or RS-485,
DCD Wait Delay
 is set to blank.
