NAME RANGE DESCRIPTION
Receive Squelch 00 .. 2147483647 Receiver squelch time in milliseconds.
A typical Receive Squelch is 00.
Pre-Transmit
Delay
00 .. 2147483647 Pre-transmission RTS on time in milliseconds.
A typical Pre-Transmit Delay is 15.
Post-Transmit
Delay
00 .. 2147483647 Post-transmission RTS off time in milliseconds. This must be at
least 2 character times for reliable communication. A typical
Post-Transmit Delay is 3 character times. Refer to Table 3 for
character times at various baud rates.
CTS Timeout 00 .. 2147483647 Clear to Send (CTS) transmit timeout period in milliseconds.
A typical CTS Timeout is 10.
ENQ Count 00 .. 32767 Default number of Enquiries (ENQs) to be retransmitted.
A typical value is 3.
NAK Count 00 .. 32767 Default number of Negative Acknowledgements (NAKs) to be
retransmitted.
A typical value is 3.
ACK Timeout 00 .. 32767 Time duration to wait for an Acknowledgement (ACK) from the
host station (1/38 sec).
A typical value is 38 (1 second).
Master Address 00 .. 254 The address of the host (source) station with which this DPA is
communicating. Address 255 is reserved as a broadcast address.
RTU Address 00 .. 254 The destination address this RTU is to respond as (0 through
255). Address 255 is reserved as a broadcast address.
Valid Status -128 .. 127 4 Entries indicating acceptable Status return values from the
host. These status values apply only to events issued by the
master, and not the status of the message.
These values are typically set to 00.
Event Buffer Size 1 .. 32000 Size of the ANSI event buffer.
A typical value is 1000.
Spontaneous
Timeout
00 .. 32767 Spontaneous event timeout (in milliseconds) before a failure is
logged.
A typical value is 5000.
DI Retries -1 .. 255 Number of digital event data retries before discarding event
(-1 try forever).
A typical value is 3.
AI Retries -1 .. 255 Number of analog event data retries before discarding event
(-1 try forever).
A typical value is 3.
EV Retries -1 .. 255 Number of EV event data retries before discarding event
(-1 try forever).
A typical value is 3.
SPA Event Retries -1 .. 255 Number of SPA events retries b efore discarding event
(-1 try forever).
A typical value is 3.
