Timeout: The time that an RTU will wait for a reply to its first message. If Message Retries is set to 1 or
greater, the RTU will try sending the message again. The time waited for a reply to all other message
attempts depends on how many message attempts have already been sent and on the Global Timeout
setting (as defined in Configuration, System Parameters) as detailed below.
Attempt Time waited for reply (milliseconds)
1 Timeout
2 Timeout + Global Timeout
3 Timeout + (Global Timeout x (1<Random<2))
4 Timeout + (Global Timeout x (2<Random<4))
5 Timeout + (Global Timeout x (4<Random<8))
etc
Where Random is a random number between the upper and lower limits defined above.
Example: Timeout=4000 ms, Global Timeout=1000 ms. The wait time after each message attempt is
therefore in the following ranges:
After attempt 1: Wait = 4000 ms
After attempt 2: Wait = 5000 ms
After attempt 3: 5000 < Wait < 6000 ms
After attempt 4: 6000 < Wait < 8000 ms
After attempt 5: 8000 < Wait < 12000 ms
IP Address: (For CP-xx RTUs only) The IP (internet protocol) address of the Target RTU. A local area
network may be used to communicate with a CP-xx RTU that has an Ethernet option board. Each number in
the IP address can have values in the range of 0-255.
CTCSS freq: This is the frequency to use for encoding outgoing FSK radio messages. CTCSS frequencies
can be configured from 67.0 to 250.3 Hz. CTCSS frequencies are used to modulate (encode) a TX signal so
that only radios that have the corresponding CTCSS frequency can decode and hear the TX signal. CTCSS
encoding is only available with PC-1/MC-1 radio option boards and must be ordered as an extra.
Wake Up RTU From Power-Down Mode? (Only applicable to radio ports) When this option is ticked, the
message will be preceded by 4000ms of carrier signal. This will cause a powered-down outstation RTU to
wake-up if the outstation RTU port is enabled to wake the RTU up. After waking an RTU up (after the first
successful message), subsequent messages do not have 4000ms of Pre-Tx carrier. However, another
wakeup message is generated if the local port has been inactive for more than 2 minutes and the last
message is not from the powered-down RTU.
