User manual

 DCD Control
Radio button selection for RS-232 DCD (Data Carrier Detect) mode
• Active – DCD is always asserted
• Switched – follows the radio carrier and data sent to DTE
 DTE Baud Rate
Select 1200/2400/4800/9600/19200 to configure the port speed of the COM Port
 DTE Data Format
User Selectable; Default = 8 bits, no parity, 1 stop. Other options include:
• 8 bits, no parity, 2 stop
• 8 bits, odd parity, 1 stop
• 8 bits, odd parity, 2 stop
• 8 bits, even parity, 1 stop
• 8 bits, even parity, 2 stop
• 7 bits, no parity, 1 stop
• 7 bits, no parity, 2 stop
• 7 bits, odd parity, 1 stop
• 7 bits, odd parity, 2 stop
• 7 bits, even parity, 1 stop
• 7 bits, even parity, 2 stop
 Data Fwd Timer
User Selectable to set the timing between data blocks in a transmission to accommodate some RTU’s special
timing requirements:
• Normal = 15 ms (default)
• Fast = 5 ms (do not use for baud rates below 2400 b/s)
 Break
Select the device response to break signals (protocol dependent) on the COM Port:
• Ignore break - unit does not transmit or receive break signals
• Transmit break - unit transmits and receives break signals
 Deferred Rx-Data Delivery
This field sets the period of time the unit waits until delivering received data to the COM Port. Range is 0 to 255 ms
in 1 ms intervals (keeps delays minimum for protocols susceptible to inter-character delays).
