Connectors and Cabling for the 8-Port Asynchronous/ Synchronous
RS-232 GRWIC
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 router. See Figure 23 on
page 51
The 8-port serial RS-232 GRWIC enables applications such as legacy protocol transport, console server, and dial access
server. Combining a high-density serial GRWIC with the Cisco CGR 2010 router enables utilities to transport Supervisory
Control and Data Acquisition (SCADA) over an IP network.
Figure 23 Cisco 8-Port Serial Async/Sync RS-232 GRWIC
The 8-port serial GRWIC has connectors and cabling that allow high-port densities in the compact GRWIC form factor.
The 8-Port Asynchronous/Synchronous GRWIC uses two high-density 4-port connectors. Each connector supports four
ports of EIA-232 with data communications equipment (DCE) or data terminal equipment (DTE) interfaces. All four ports
on one cable use the same DTE/DCE mode. Table 11 on page 52 outlines the cable specifications for the 8-Port
Async/Sync RS-232 GRWIC.
Note: The operating temperature range for these cables is -40º C to +60º C.
