Chapter 2: Installing the monitor
15
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.
Step 2:
Connect serial
cable
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.
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.
