Part No. 001-4008-101/102
DCD Control
This field selects the mode of the RS-232 DCD (Data Carrier Detect)
z
Active - always asserted
z
Switched - follows the radio carrier and data sent to DTE
DTE Baud Rate
This field selects the port speed of the COM Port (independent of Network Speed)
z
300
z
1200
z
2400
z
4800
z
9600
z
19200
For best results, Dataradio recommends using the same rates for both the COM Port and Network Speeds.
DTE Data Format
This field selects the format for the COM Port. All units in a network must use the same DTE data format:
8 bits, no parity, 1 stop 7 bits, no parity, 1 stop
8 bits, no parity, 2 stop 7 bits, no parity, 2 stop
8 bits, odd parity, 1 stop 7 bits, odd parity, 1 stop
8 bits, odd parity, 2 stop 7 bits, odd parity, 2 stop
8 bits, even parity, 1 stop 7 bits, even parity, 1 stop
8 bits, even parity, 2 stop 7 bits, even parity, 2 stop
Data Fwd Timer
This field selects the timing between data blocks in a transmission to accommodate some RTU’s special
timing requirements:
z
Normal - 15 ms option
z
Fast - 5 mS option (do not use for baud rates below 2400 b/s)
Break
This field selects the unit’s response to break signals on the COM Port:
z
Ignore break - unit does not transmit or receive break signals
z
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.)
