Sentinel & PimaGuard
Installation Guide
If Communication 1 fails, events will be sent via Communication 2 until timeout is over. If Communication 1 is
restored by Idle’s ACK, the events in Communication 2 will not be looped back to it; all the new events will be
sent via Communication 1, but Communication 2 will still try to send the former events from the buffer until
timeout is over.
Format
5. Select the format for the current configuration. The structured formats are listed in Appendix D, page 29;
Constrains and limitations are listed in Appendix B, page 27.
ACK timeout
6. Set the ACK waiting timeout (in seconds). Each format has a default ACK and by setting the timeout the
ACK is enabled.
• In ‘Software’ mode, the PimaGuard requires the ACK from the Central Monitoring Station, in the protocol;
• In ‘External’ mode, the Mcard generates the ACK if a value is set;
• Three consecutive transmissions timeouts with no ACK, triggers a fault (see Appendix C, page 28);
• When working in TCP type, ACK is not required, unless the Central Monitoring Station requires it. If no ACK
is set, TCP errors will be reported as communication errors;
• When working in UDP type, ACK is required for generating a communication fault
• In External mode, if a filter is set and an ACK is requierd, the ACK is sent anyway, even if the event is
not within the filter’s range (except for time filters). This is to enable the external decoder to keep
running in anyway.
Idle timeout
7.
Set the Idle timeout in seconds. To view ACK & Idle patterns, see "Communication formats" on page 14.
Idle ACK
8. If set to ‘Active’ in
‘Software’
mode, an ACK from the Central Monitoring Station is expected for the Idle.
If set to ‘Active’ in
‘External’
mode, the PimaGuard will send an ACK for any received Idle frame.
Port number
9. There are two options: if the mode is Software or Repeater Out, the port is a destination port; if the mode
is External or Repeater In, the port is a listening one.
IP/URL
10. Set the destination IP or URL. If the communication channel is set as Repeater Out or Software, the
destination IP/URL must be set. If the channel is set as Repeater In or External, these does not have
to be set. After setting the IP or URL, transmissions will be recived only from the specified destination
address..

Filters
For the External mode only, see page 25.
The formats are listed in Appendix D, page 29.
‘Software’ and ‘External’ modes have the same formats for input and output, and the same ACK & Idle patterns
.
• In ‘Software’ mode, Idle is reported if no transmission is received within the timeout.
• In ‘External’ mode, Idle is expected within the interval, if no transmission is received.
If the IP/URL field is left blank, the PimaGuard will accept transmissions from any IP
with the specified Port number.
