Step 5: Making Serial Cable Connections
RS232 serial communication enables the Command Line Interface (CLI) and
Command Line Utility (CLU) on your PC to monitor and control the VTrak. On
VTrak, RS232 communication goes through the RJ11 serial connector on each
controller.
Figure 21. Serial communication goes through the RJ11 connector
To set up a serial cable connection:
1. Attach the RJ11 end of the RJ11-to-DB9 serial data cable, supplied with the
VTrak, to the RJ11 serial connector on one of the controllers.
2. Attach a null-modem cable to the DB9 end of the RJ11-to-DB9 serial data
cable.
3. Attach the other end of the null-modem cable to a serial port on the Host PC
or Server.
You will establish a serial connection on the Host PC or Server in Step 7 (see
page 25). At this time, continue with Step 6.
Note
The DB9 connector on the VTrak controller is for a UPS support,
which is planned for a future release.
