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 3-23
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 3-23 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 3-11
outlines the cable specifications for the 8-Port Async/Sync RS-232 GRWIC.
Note The operating temperature for these cables is -40º C to +60º C.
