On the PMI/OWSmotherboard, two network interface modules are used to connect tothe two networks of interest. With the JC-MER-CXB, this samefunctionality can be provided in a compact and reliable configuration.On the front panel of the JC-MER-CXB is a BNC connector for theARCNET and an RJ-45 connector for the Ethernet.Resident in the JC-MER-CXB is an embedded computer with a solid-state flash disk capable of executing an application program. This user-supplied application program routes packets between ARCNET andEthernet networks that utilize the same network layer or serve as agateway between different protocols used by the ARCNET and Ethernet networks. For example, a popular transport layer for Ethernet is TCP/IP. To route between ARCNET and Ethernet at the network layer (IP), ARCNET would need to be operating a TCP/IP stack as well. For all other situations where different higher-level protocols are involved, a gateway program would be needed to effect connectivity between ARCNET and Ethernet. Either situation can be addressed by the JC-MER-CXB.To provide ARCNET-to-Ethernet connectivity within a Metasyssystem, the JC-MER-CXB was created by installing the necessaryapplication program onto the flash disk. This product replaces theJC-MH-16, JC-EP-RG and JC-EP-CS version or model of theEthernet router. To configure the JC-MER-CXB, a laptop computerrunning a terminal emulation program, like HyperTerminal, isattached to one of the COM ports using a null-modem cable. Onceconfigured, the program runs continually.TD060100-0MA7Electrical SPECIFICATIONS DC AC Input voltage: 10–36 volts 8–24 volts Input power: 8 W 8 VA Input frequency: N/A 47–63 Hz Environmental Operating temperature: 0°C to +60°C Storage temperature: –40°C to +85°C Humidity: 10% to 95%, non-condensing Shipping Weight 1 lb.
