GPO Setup
The GPO Setup is used to select what input or alarm the GPO follows. If an alarm
occurs on an input associated with the GPO, the GPO will change its polarity
setting. If Follow Alarms is selected, the GPO will change its polarity setting
whenever an alarm occurs on any input.

IP Configuration
: The IP configuration selection option is used to configure the
CMN-41 for Ethernet communication. The Ethernet interface provides a high-speed
communication link to the third party applications (such as SNMP) over standard
LAN and Internet networks. The interface conforms to industry Ethernet standards:
•
Connection via a standard RJ45 socket
•
Automatic detection and switching between 10Base-T and 100Base-T
•
TCP/IP stack is fully compliant with RFC2500, “Internet Official Protocol
Standards”
•
Fully compliant with IEEE 802.3 Ethernet standard
The interface can accept a static IP address, or it can obtain an IP address
dynamically from a DHCP server. The IP Address, Subnet Mask, Gateway
Address, DHCP enable, and Port are programmable from the unit’s Ethernet Setup
menu. The settings are performed in the IP Configuration screen.
−
DHCP: The Dynamic Host Configuration Protocol (DHCP) function is used
to have the CMN-41 automatically configure an IP Address, Subnet Mask,
and Gateway every time the unit is powered on. The IP Address is dynamic
and could change each time the CMN-41 is powered on. DHCP Enable is set
to OFF by default.
−
IP Address: The IP Address is used to select a static IP address (unless DHCP
will be used). The IP address must not be the same address as another
instrument or PC on the network. Network conflicts will occur if two devices
have the same IP address. See the System Administrator to determine a static
IP address that will avoid conflicts.
−
Subnet Mask: The Subnet Mask is used to configure the Subnet Mask on a
network if DHCP is not enabled. If DHCP is not used to automatically detect
the Subnet Mask on a network, the Subnet Mask must be manually
configured. Unlike the IP address, the Subnet Mask must be the same Subnet
Mask as the network Subnet Mask. See the System Administrator to
determine the Subnet Mask.
−
Gateway: The Gateway is the network address that provides access to an
outside network. Use the Gateway submenu to configure the Gateway on a
network if DHCP is not enabled. If DHCP is not used to automatically detect
the Gateway on a network, the Gateway must be manually configured. Unlike
the IP address, the Gateway must be the same Gateway address as the
network Gateway address. See the System Administrator to determine the
Gateway address.
•
System Time
: This selection option allows the setup of the clock display’s date and
time.
