The 8-Port Asynchronous/Synchronous Grid Router WAN Interface Card (GRWIC) provides low speed synchronous/asynchronous serial connections supporting EIA-RS232 for the Cisco CGR 2010. The 8-port serial RS-232 GRWIC helps customers to enable applications such as legacy protocol transport, console server, and dial access server. Combining a high density serial GRWIC with the Cisco CGR 2010 enables utilities to transport Supervisory Control and Data Acquisition (SCADA) over an IP network.
