Ordering and Installing the Inlet Connector Lock

NOTE: The Inlet Connector Lock is available only on the LX-4008, LX-4016, and LX-4032. It is not supported on the LX-4048.

You can use an inlet connector lock to lock the AC power cord to the LX-4000 Series unit. MRV does not supply this lock. You can order the connector lock (part number 85910020) from Panel Components Corporation. The web address at which you can order the connector lock is: www.panelcomponents.com/first.html. See Figure 26 for installation instructions.

Connecting to the Diagnostic Port (Port 0)

NOTE: Display problems may occur during bootup when you attach a VT420 terminal to the DIAG port (port 0) and the VT420 display setup is configured to Smooth-2 Scroll. To avoid this, change the VT420 scroll setting to Jump Scroll.

Connect the provided serial port cable to the DIAG connector (port 0), and the other end to your terminal. You can use this direct connect serial link to send commands to the boot loader and diagnostics. This port is used to log system messages during bootup. You can also use port 0 to manage and configure the LX-4000 once the unit completes the bootstrap process.

Modem Control/Hardware Flow Control

LX-4000 Series serial ports can be set up to support RTS/CTS flow control. The adapters shown in Figure 27 and Figure 28 illustrate RTS/CTS flow control for DTE devices using DB25 and DB9 connectors. Figure 29 illustrates RTS/CTS flow control for a DB-25 connector on a DCE device like a modem. LX-4000 Series serial ports can also be set up to support modem control (except for the DIAG port (port 0)). Figure 27, Figure 28, and Figure 29 support modem control as needed. Only Figure 28 and Figure 29 support concurrent modem control and RTS/CTS flow control between the LX-4000 Serial Port and the attached device.

The adapter shown in Figure 29 supports modem control.
