Compact 5000 I/O Serial Module Features Chapter 3
Common Module Functions
The module supports the following terms, definitions, and parameters.
Table 3 - Common Module Function
Function Definition Available Options
Baud Rate The communication speed of each channel. • 9600
•1200
•2400
•4800
• 19200 (default)
• 38400
• 57600
• 115200
Data Bits The number of data bits are used to represent one
character of data.
•7 bit
•8 bit (default)
Parity Sets the parity of transmitted data for error detection. It
is created with data files and used to check data integrity
and help with data recovery.
• None (default)
•Even
•Odd
Stop Bits This parameter sets the number of stop bits for
each data value sent.
•1 (default)
•2
Serial Media Type of media that is connected to the channels
communication ports.
• RS-232C (default)
•RS-422
•RS-485
Duplex The type of communication that is used by each channel. • No Handshake (default)
• Full-duplex
•Half-duplex
Continuous Carrier A carrier frequency that is transmitted even when data is
not being sent.
Continuous carrier is selected if you want to use it with
half-duplex communication. The checkbox is unavailable
if you have chosen something other than half-duplex
communication, or if you have chosen Master as your
protocol. The default option is cleared when enabled.
•On
•Off
RTS Send Delay Enter the time (x20 ms) to delay transmitting the first
character of a message after turning on the RTS line. The
default value is 0.
• 0…255
(default = 0)
RTS Off Delay Enter the time (x20 ms) to delay turning off the RTS line
after the last character has been transmitted. The default
value is 0.
• 0…255
(default = 0)
DCD Wait Delay The number of seconds to wait before lowering the DCD
modem line. When DCD is high, the controller is in the
middle of transmitting data. This delay may be needed
because of the latency in the sending radio transmissions.
• 0…255
(default = 1)
