Chapter 2: Installing the monitor

Step 2: Connect serial cable

Important

•To reduce the risk of voiding FCC and CE compliance and reducing the performance of the ET 350 monitor, when making your own cable, reduce the sensitivity of the ET 350 monitor to electrical and radio frequency noise by connecting the cable shield to the connector shield (360º shield) on both ends of the cable.

•Before attaching or removing communication cables, disconnect power to the ET 350 monitor.

To connect the video signal cable, follow these steps:

1.If the monitor has a hatch, the hatch must be open to access connectors. Remove the four #6-32 Phillips screws affixing the hatch to the monitor and open the hatch cover. For an illustration of the locations of these screws, refer to Figure 13 on page 38.

2.Connect one end of the video signal cable to the VGA signal cable connector on the side of the monitor.

3.Tighten the screws on the signal cable.

4.Connect the other end of the signal cable to the video adapter port on the computer.

5.Tighten the screws of the signal cable to ensure proper connection.

6.After connecting the video signal cable to the monitor and computer, make sure you have the latest video drivers for the video adapter. You may be able to download the most recent drivers from the video adapter manufacturer’s web site.

The ET 350 monitor uses a 9-pin COM port for touch screen communication with the host computer. The standard length of the serial cable is 6 feet. There are 25-foot and 50-foot cable options available.

Use a standard cable or make one using the “Serial port RS-232C connector” in Appendix C. Note that the pin-out presents the ET 350 monitor as a Data Communication Equipment (DCE) device so that a “straight-through” cable can be used.

To connect the serial cable:

1.If the monitor has a hatch, make sure that the hatch is open (it should have been opened when connecting the video cable). The hatch must be open to access connectors.

2.Connect one end of the serial cable to the serial cable connector on the side of the monitor.
