Connecting Serial Cables and Devices on the DECserver
Connecting Serial Cables and Devices on the DECserver
The DECserver can be configured by the software to support one of the two sets of
modem signals. One modem set consists of:
• Clear to send (CTS)-This is the default setting.
• Request to send (RTS)-This is the default setting.
• Data set ready (DSR)-This is the default setting.
• Data terminal ready (DTR-This is the default setting.
The second set consists of:
• Ring indicator (RI)
• Data signal rate selector (DSRS)
• Data carrier detect (DCD)
• Data terminal ready (DTR)
Before installing cables to the DECserver, you must find out which modem signals are
supported from the person managing the DECserver. This information is necessary to
determine which cables to use. For more information on the signals, refer to the
Network Access Software Management Guide.
Cable and Adapter Connections
Table 4-1 describes the cable connections that are compatible with the DECserver
Ethernet and serial line connectors. Wiring diagrams of individual cables are provided
for use in troubleshooting and cable building.
