•
Number of stop bits: 1 or 2
Check the printer manual to find out which parameters should be configured for your specific printer
model.
Below you can see an example configuring these parameters: speed 9600, 8 data bits, without parity
and 1 stop bit.
PRIMARY SEPI-serial0/1 Cfg>serial-parameters speed 9600
PRIMARY SEPI-serial0/1 Cfg>serial-parameters data-bits 8
PRIMARY SEPI-serial0/1 Cfg>serial-parameters parity none
PRIMARY SEPI-serial0/1 Cfg>serial-parameters stop-bits 1
Values valid for speed are from 300 to 115200. For the data bits 5, 6, 7, or 8. For parity, “even”,
“odd” or “none” and finally for the stop bits 1 or 2.
5.4. Communicating with the mIP/IPDACTs
Another aspect requiring configuration is the communication between the VisorALARM PLUS 2U
and the mIP/IPDACTs. The parameters requiring configuration are as follows:
•
VisorALARM PLUS 2U UDP port to which the mIP/IPDACTs send alarms and supervision
traffic.
•
Set time period to assume an mIP/IPDACT is “lost”: if after this configured time, supervision
traffic is not received from an mIP/IPDACT, an alarm (whose code is configurable) is sent to
the automation server as there is a probable communication problem with the said
mIP/IPDACT.
It is essential that this time is greater than the time between mIP/IPDACT retries to
those providing the service in order to avoid ‘false’ alarms.
•
IP address to check VisorALARM PLUS 2U IP connectivity: the device sends ICMP echo
packets to the configured address. In cases where responses are not received, IP connection is
considered lost and the device notifies the automation server through an event (whose code is
configurable). mIP/IPDACT supervision is cancelled until connectivity is recovered to avoid
loss of connectivity alarms being sent by each registered mIP/IPDACT. Additionally, you
need to configure how often the connectivity should be polled.
Use the following command to configure the UDP port:
PRIMARY ARLY-1 Cfg>supervision port 1234
PRIMARY ARLY-1 Cfg>
The following command configures the address to poll the IP connectivity and the polling interval:
PRIMARY ARLY-1 Cfg>monitor-ip-addr 213.4.21.187 rate 30
PRIMARY ARLY-1 Cfg>
5.5. Network Backup Parameters
Network backup is the possibility of the mIP/IPDACT having a second receiver to send alarms to and
keep-alive polls. From the VisorALARM PLUS 2U point of view, network backup consists of two
devices, one configured as main and the other as secondary or backup. Both devices should have
different gateways and if possible different Internet access providers. In this way, the possible
problems of communications between the two devices are isolated.
Use the following syntax to configure each of the backup parameters:
