188 DL-V3 User Manual Rev 3
The Com Ports dialog appears, see Figure 41 above. Select a COM port to use as the virtual serial port
for the Ethernet device. Notice that you are unable to select previously assigned ports. Click OK to
return you to the main CPR Manager dialog.
D.2.4.3 Redirector Configuration Completion
After completing the steps in the three sections starting on Page 187 through to the section above,
click the Save button in the Lantronix Redirector Configuration dialog, shown in Figure 40 on Page
186, and follow the prompts. Click the Close button to close the Redirector program. The Windows
system may require a reboot when a new COM port is selected.
The system is now ready to be used with HyperTerminal, CDU, or other serial communications
software. Ensure that the serial settings are identical to those configured for the Ethernet device, that
is 115200 baud, 8 data bits, no stop bits, 1 parity bit, hardware flow control and the same PC/laptop
COM port as selected in the “Configure Virtual Serial Port” section on Page 187.
D.3 Alternative Serial Configuration
Serial Command Mode is an alternative method to configure the Ethernet network and serial settings.
This method is complicated by the fact that there is no direct access to the Ethernet device because it
is an embedded part connected internally to COM3. The following paragraphs describe the detailed
process of configuring the Ethernet via the Serial Command Mode.
D.3.1 Physical Connections
To physically connect the Ethernet to the DL-V3, follow these steps:
1. Connect a serial null-modem cable from your Laptop to the DL-V3 COM1 port
2. Connect a serial null-modem cable from your Laptop to the DL-V3 COM2 port
1 serial null-modem cable may be connected from the laptop and switch between COM1 and
COM2 on the DL-V3. You can avoid switching if you have two serial connections on your
laptop and two null-modem cables. Also, if your laptop has only USB connectors, you need a
USB to serial adaptor between the null-modem cable and the laptop’s USB connector.
3. Connect the power cable to DL-V3 power port, power and switch on the unit with the button
on its front.
D.3.2 PC/Laptop Software
HyperTerminal communications software is recommended for COM1 communications to the DL-V3.
From Window’s Start menu, select Programs | Accessories | Communications | HyperTerminal. The
HyperTerminal default communications parameters should be set to those listed Table 83 on
Page 189.
