|  | Configuring the NetSpot Device Installer for TCP/IP Environment
| Setting Discovery Criteria

This section describes the procedure for setting discovery criteria.
There are three ways for discovering devices, as listed below.

Broadcast Discovery: | Search for undetermined devices.
IP Address Range Discovery: | Search for devices within a specified IP address range.
Multicast Discovery: | Search for specific devices using Multicast.

| As the default setting, NetSpot Device Installer for TCP/IP is configured for broadcast discovery on the local subnet to which the computer running NetSpot Device Installer belongs.
| If you are installing NetSpot Device Installer on an operating system which has the Windows Firewall function, such as Windows XP Service Pack 2, and the Windows firewall function is enabled, you cannot display unconfigured devices in the device list, nor carry out Broadcast Discovery and Multicast Discovery on a network other than the local subnet without registering NetSpot Device Installer as a program that is not to be blocked in Windows Firewall. For instructions on how to make registration settings, refer to the Readme file. (If you have registered this software in Windows Firewall by following the instructions during installation, it is not necessary to perform this procedure.) If you do not register it, you can use the IP Address Range Discovery function to discover the devices for which IP addresses have been set on a network other than the local subnet. For information on how to do this, refer to Setting IP Address Ranges for Discovery.

Setting Broadcast Discovery

To use broadcast discovery on the local subnet or at specified broadcast addresses, follow the procedure below.

1. Select [Discovery Settings] from the [Options] menu.
2. Click the [Broadcast] tab in the [Discovery Settings] dialog box.
3. To add new broadcast discovery settings, click the [New] button.
   To change broadcast discovery settings already specified, select the broadcast discovery setting that you want to change from the list, and then click the [Edit] button.
   To delete the broadcast discovery settings already specified, select the broadcast discovery setting that you want to delete from the list, and the click the [Delete] button.
4. Specify the broadcast discovery criteria in the [Specify Broadcast Discovery Settings] dialog box.

   | [Broadcast Address]: Input the broadcast address for the subnet where you want to discover devices. You cannot set this item for the local subnet. [Subnet Mask]: Input the subnet mask for the network where you want to discover devices. You cannot set this item for the local subnet. [Gateway Address]: Input the gateway address for the network where you want to discover devices. [Timeout]: Sets the timeout for devices that do not respond during discovery, from 1-9 seconds. [Discover Devices that are Not Configured]: Select this option to discover [Not Configured] Canon devices. Select the check box to perform the discovery. [SNMP Community Names]: A list of the SNMP community names to use for discovering devices or collecting device information. [Community Name]: Specify the SNMP community name to use for discovering devices or collecting device information. Input the community name here, and then click the [Add] button to add the community name to the [SNMP Community Names] list. To delete a community name, select it from the [SNMP Community Names] list, and then click the [Delete] button.

   | When you make the initial settings of [Not Configured] devices, the subnet mask and gateway address set here are set automatically in the [Initial Settings] dialog box. If the gateway address is not correctly specified, devices may not communicate across subnets after you execute [IP Address Settings] for [Not Configured] devices.

5. Click the [OK] button to complete the settings.

   | The settings are now enabled.

Setting IP Address Ranges for Discovery

To set one of more IP address ranges used during discovery, follow the procedure below.

1. Select [Discovery Settings] from the [Options] menu.
2. Click the [IP Address Ranges] tab in the [Discovery Settings] dialog box.
3. Click the [New] button to add a new discovery address range.
   To change a discovery range already specified, select the discovery range that you want to change from the list, and then click the [Change] button.
4. Specify the discovery criteria in the [Specify IP Address Range] dialog box.

   | [First Address]: Input the first address of the address range for discovery. [Last Address]: Input the last address of the address range for discovery. [Timeout]: Sets the timeout for devices that do not respond during discovery, from 1-9 seconds. [SNMP Community Names]: A list of the SNMP community names to use for discovering devices or collecting device information. [Community Name]: Specify the SNMP community name to use for discovering devices or collecting device information. Input the community name here, and then click the [Add] button to add the community name to the [SNMP Community Names] list. To delete a community name, select it from the [SNMP Community Names] list, and then click the [Delete] button.

   | To delete a community name, select the community name in the [SNMP Community Names] list, and then click the [Delete] button.

5. Click the [OK] button to complete the settings.

   | The settings are now enabled.

Setting Multicast Discovery

To use Multicast Discovery, follow the procedure below.

| To be able to use Multicast Discovery, the router must support this function.
| This discovery method will only find Canon devices that support Multicast Discovery. For information on whether your device is compatible with Multicast Discovery, refer to the documentation supplied with the device.
| Only devices where both the Multicast Discovery scope name and SNMP community name are matched will be discovered. If the device has been set up not to respond to Multicast or SNMP discovery, it will not be discovered.

1. Select [Discovery Settings] from the [Options] menu.
2. Click the [Multicast] tab in the [Discovery Settings] dialog box.
3. To add new discovery settings, click the [New] button. To change existing discovery settings, select the setting that you want to change from the list, and then click the [Edit] button. To delete an existing discovery setting, select the setting from the list, and then click the [Delete] button.
4. Specify the discovery criteria in the [Specify Multicast Discovery Settings] dialog box.

   | [Number of Routers]: Select the number of routers through which the Multicast messages can pass. When set to 0, only the local subnet will be searched. [Timeout]: Sets the timeout for devices that do not respond during discovery, from 1-9 seconds. [Multicast Scope Names]: A list of names to use for Multicast Discovery. [Scope Name]: Specify the scope name to use for multicast discovery. Input the scope name here, and then click the [Add] button to add the name to the [Multicast Scope Names] list. To delete a scope name, select the scope name you want to delete from the [Multicast Scope Names] list, and the click the [Delete] button. You can set up to 10 scope names. [SNMP Community Names]: A list of the SNMP community names to use for discovering devices or collecting device information. [Community Name]: Specify the SNMP community name to use for discovering devices or collecting device information. Input the community name here, and then click the [Add] button to add the community name to the [SNMP Community Names] list. To delete a community name, select it from the [SNMP Community Names] list, and then click the [Delete] button.

5. Click the [OK] button to complete the settings.

   | The settings are now enabled.
