User Manual

Destination identification

When retrieving device data, the RDS Plug-in will only communicate with the registered device. The

RDS Plug-in will not communicate with any other device on the LAN. When sending the retrieved

device data, the RDS Plug-in communicates only with the UGW server registered in the RDS Plug-in

configuration settings. The IT administrator for iWEMC can regulate access to the configuration

settings through user privileges.

Communication protocol between device and RDS Plug-in (device

to RDS Plug-in)

Table 2 lists the communication protocols and port numbers used to facilitate the data retrieval

from device to RDS Plug-in. As shown in the table, the communication protocols are proprietary to

Canon except for SNMP. All of the listed protocols are used for managing devices. SNMP is also an

RFC-defined protocol for managing network devices. These protocols are not capable of accessing

or retrieving image data or content information such as Address Book data.

a Web server.
