1-4. Outline of Communication
A controller (PC) communicates with a display according to the communication data format. Communication is started by
issuing a command from the controller. Communication is terminated when the display sends return data (an answer message) to the controller after it receives the issued command.
It is inhibited that a controller sends multiple commands at a time.
Therefore, a controller cannot send other commands until return data is sent back from a display after it sends one command. The display sends return data after command processing is completed.

SNMP
2-1. SNMP
This unit installs SNMP (Simple Network Management Protocol). SNMP is a standard protocol for
network management that was standardized in IETF (Internet Engineer Task Force).
By using SNMP, the management information of equipment connected to a network can be gotten via a
network. The information of multiple equipment gotten using SNMP can also be unitarily managed by
using SNMP management software.
The equipment corresponding to SNMP has a “management information database” called MIB (Management Information Base) in the inside of equipment. In SNMP, the bidirectional communication of data
contained in MIB is realized between a “management system” and “management object system” that exist
in a network.
In MIB, there is the standard MIB prescribed by RFC. Especially, MIB-II is its representative MIB.
MIB-II was established to manage a network. MIB-II is installed in much network equipment such as a
PC, router, and switch as a standard feature. This unit installs this MIB-II.
Monitoring and monitored sides exist when equipment is monitored via a network using SNMP. The
monitoring side is called an “SNMP manager”. It is mainly constituted by the software of PC. For the
monitored side, a module called an “SNMP agent” is installed. SNMP-compatible equipment transmits
MIB information to an SNMP manager via this SNMP agent. This unit installs this SNMP agent. This
unit can realize the communication with a general-purpose SNMP manager using this SNMP agent.
Basically, an SNMP agent replies only when an inquiry is sent from an SNMP manager.
The SNMP manager periodically inquires the equipment, which it manages, about MIB information. This
way to get information is called “polling”. In polling, equipment replies using a response command when
an SNMP manger sends a request command to equipment. By polling, therefore, equipment can be
monitored without applying a high load to the equipment.
On the other hand, notifi cation can also be done from the equipment side to an SNMP manager. This noti-fi cation is called a “trap”. Using this trap, when a serious trouble occurred in equipment, it can be notifi ed
to the SNMP manager in a short time.
This unit is compatible with the two polling and trap protocols described above. Equipment can be
effi ciently monitored using these protocols.

The setting below is required to use the SNMP function of this unit. (Set according to your network
environment and SNMP management environment.)
. Community and its Community property
. Authentication trap
. Host restriction
The Web server function of this unit is used for setting. Refer to the Operation Manual of this unit for the
operation of the Web server.
The contents of each item and the setting of SNMP are fully described in this specifi cation.
2-4. Operation of SNMP Setting Window

2-4-1. Community
A Community name is used as the password for SNMP access. The request received from an SNMP manager is accepted when the Community name contained in the request coincides with the Community name
set. The request is rejected when the former does not coincide with the latter.
A maximum of three Communities can be set.
There are “Rights” and “Trap destinations” items in the property of Community. The property can be set
for each set Community.
n
When multiple Communities are set, all set Communities are validated.
1. Rights
The rights that can be set are as follows:
Read Only: An SNMP manager can reference MIB information using this Community name.
Read Write: This Community must be set when a write request is sent from an SNMP manager.
Other: Do not set this option because it is used for the function extension in future.
2. Trap destinations
When Trap destinations are set, during trap occurrence, a trap is notifi ed to the equipment set as trap desti-
nations using the Community name set.
Up to four Trap destinations can be set to one Community.
Trap destinations are not set in default.
n
This product can be set on only the Web screen because it does not install the automatic setting function
of Trap destinations.
3. Setting procedure of Community
Community can be added, edited, and removed.
The addition, editing, and removal procedures of Community are described below.
Addition of Community
1. Click the [Add] button.The “Community name”, “Rights”, and “Trap destinations” text boxes, and [Set|to|List] and
[Cancel] buttons are validated.
2. Type the Community name you want to add.
3. Set the Rights of Community and the Trap destinations you want to add.
When you want to save the setting, click the [Set|to|List] button and then click the [Apply] button at
the bottom of the window.
m
. Click the [Cancel] button when you want to discard the setting during setting.

2-4-2. Authentication Trap
An authentication trap is the trap for making it detect by an SNMP manager that an illegal access was
gained to this unit using an SNMP protocol.
. The authentication trap is validated when this check box is selected. A trap is transmitted when an
illegal access is gained.
. The authentication trap is invalidated when this check box is not selected. A trap is not transmitted even
if an illegal access is gained.
n
Be sure to click the [Apply] button when you edited setting.
2-4-3. IP Restriction of Host
It is possible to put restrictions on the IP address of an SNMP manager, as one of the security countermeasures, which communicates using an SNMP protocol.
. IP address restriction is invalidated when you select “Accept packets from any host”.
. Only the SNMP access from an SNMP manager that has the set IP address is accepted when you select
“Accept packets from those hosts”. The SNMP access from an IP address that has not been set is rejected.
m
. Up to four IP restrictions can be set.
. Be sure to click the [Apply] button when you edited setting.

2-5. MIB to Be Installed
This unit installs MIB-II.
MIB-II is the most representative standard MIB. It is installed in various network products.
The statistical information on the amount of network traffi c or the number of transmitted and received
packets is defi ned, and the change or transition can be monitored by polling the information periodically.
Additionally, the management items to be installed can be defi ned using a TCP/IP device so as to get the
information effective for the monitoring of the network communication state.
Refer to RFC1213 for the detailed defi nition of MIB-II.
2-6. Information to Be Notifi ed on Trap
In software version 2.0 or later, the software have a function that transmits error information to this unit.
The error trap and authentication trap are installed.
