TX - Access the data stream being received from the network. RX - Access the data stream being transmitted to the network. MON ¦ Provides a non-intrusive access point to the data stream. TX - Monitors the data stream being received from the network RX - Monitors the data stream being transmitted to the network. NOTE: The DDM+ H2TU-C does not have the DSX-1 Bantam Jacks option. RS-232 DB-9 CONNECTOR ¦ Used to access performance monitoring data, perform loopbacks and provision units via VT100 emulation applications such as Hyper Terminal – Private Edition, ProComm Plus, and Telnet. ¦ There are two types of terminal emulation modes, Manual and Real-Time. Use “CTRL-T” to toggle between the two modes. Manual Emulation Mode: Press the space bar 3 times to manually update the screen. Print screen and log file commands are available in this mode. Real-Time Emulation Mode: The default mode. Print screen and log file commands are not available in this mode. Cursor placement and screen highlighting are enabled. ¦ Provision terminal port as follows: Data Rate — 1.2 to 19.2 kbps Asynchronous Data Format — eight data bits, no parity (none), one stop bit ¦ When using a PC with terminal software, be sure to disable any power saving programs.
