NTI RACKMUX KVM Drawer with NODEMUX Switch

Configuration

Baud Rate

In order for a terminal to communicate with the NODEMUX, the terminal and NODEMUX must each be configured for the same baud rate.

Press <W> from the Administration Mode menu (page 8) to enter Switch Configuration mode. (Fig. 15) Press <Tab> once to move the cursor bar to highlight "RS232 BAUD RATE". The default setting is 9600.

Press <Up Arrow> or <Down Arrow> to change the selected baud rate to 300,600,1200,2400,4800, or back to 9600.

Do not change this field.

Figure 15- Switch Configuration Mode screen

Note: When used in a RACKMUX, the NODEMUX can only be used as a stand alone switch. Do not change this setting.

In the event the setting is changed from "stand alone" to "slave", when the switch is power cycled the OSD menu will no longer work. To restore the setting back to "stand alone", factory default settings must be restored via a terminal connected to the RS232 control port. See the RS232 Command "CF" on page 19 to restore default settings.

Loop Back

In order for an RS232 command and a response to the command to be viewed at the terminal screen, the NODEMUX must have its Loop Back feature enabled.

More than one NODEMUX may be connected to a terminal at a time. To do so, a Matrix-Y-1 cable (available from NTI) must be used. (See Fig. 16). For each additional NODEMUX connected, another Matrix-Y-1 cable will be required.

If the NODEMUX is one of two or more switches being controlled via RS232, and if the NODEMUX is not that last switch in the series of switches controlled, then this setting should be changed to "DISABLED".

If the NODEMUX is the only device controlled via RS232 , or if it is the last device in a series of devices being controlled, then this setting should remain "Enabled". (See Figure 16)
