Appendix E IR-IP Interface Module E.1 Introduction Introduction IR-IP is a high-performance, miniature IP router based on RAD's unique IP router chip, the ChipRouter. IR-IP works by taking each Ethernet frame from the LAN and determining whether the IP packet is destined for the IP net on the Ethernet LAN. If not, IR-IP forwards the packet to the WAN link. IP packets received from the WAN link are automatically forwarded to the LAN if the IP net matches.
HCD-E1 Installation & Operation Manual Appendix E - IR-IP Interface Module Application Figure E-1 shows a typical application of HCD-E1 with the IR-IP module.

HCD-E1 Installation & Operation Manual Appendix E - IR-IP Interface Module When the factory-default parameters are used, the ERR indicator located on the HCD-E1 rear panel, near the IR-IP Ethernet interface connector flashes rapidly (about three times per second). The flashing of the ERR indicator also serves as a warning to the user that the IR-IP WAN interface does not send, nor does it receive packets, and therefore IR-IP can be accessed only from the LAN.
Appendix E - IR-IP Interface Module Connecting the Telnet Host HCD-E1 Installation & Operation Manual 3. Establish communication with IR-IP and assign the prescribed IP address to its LAN interface. 4. Establish again communication with IR-IP and continue the preliminary configuration in accordance with the Quick Setup Menu section below. Before starting the management and configuration activities, it is necessary to establish IP communication between your Telnet host and the IR-IP interface module.
HCD-E1 Installation & Operation Manual Appendix E - IR-IP Interface Module IP Learning Mechanism To simplify the configuration process, IR-IP has a special mechanism for configuring the IP address of its LAN interface. Setting section 1, called IP address learning, of the IR-IP DIP switch (Figure E-3) to ON enables this mechanism. The IP learning mechanism enables IR-IP to learn its LAN interface IP address by receiving frames sent by a ping utility to the prescribed LAN IP address.
HCD-E1 Installation & Operation Manual Appendix E - IR-IP Interface Module 4. Send a ping to the new address to be used by IR-IP. A confirmation should be received after the third ping: after the confirmation, the flashing will slow down to approximately twice a second.
