Console Port Signals

The console port on the RSP8 is an EIA/TIA-232, DCE, DB-25 receptacle. Both Data Set Ready (DSR) and Data Carrier Detect (DCD) are active when the system is running. The Request To Send (RTS) signal tracks the state of the Clear To Send (CTS) input. The console port does not support modem control or hardware flow control. The console port requires a straight-through EIA/TIA-232 cable. Table 5 lists the signals used on this port.
