residential area is likely to cause interference, in which case the user at his own
expense will be required to take whatever measures may be necessary to correct
the interference.

Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.

This digital apparatus does not exceed the Class A limits for radio noise emission from
digital apparatus set out in the Radio Interference Regulation of Industry Canada.

CHAPTER 3: Installation

3. Installation

This chapter describes how to connect the system cables, the screen cable, and the
power supply to the CAT5 Video Splitter System using the Remote Standard CAT5
Video Splitter or Remote Long-Range CAT5 Video Splitter in conjunction with:

• The 2-Port CAT5 VGA Video Splitter (central unit).

• The 4-Port CAT5 VGA Video Splitter (central unit).

3.1 Setting the DIP Switches (AC503A and AC503AE Only)

You can improve the picture quality and sharpness by setting the DIP switches
(located on the bottom of the remote unit) for coarse adjustment.

1. The bottom of the remote unit contains DIP-switches G, B, and R.
See Figure 3-1.

Figure 3-1. AC503A(E) DIP-switch settings for coarse adjustment.

2. RGB compensation demands identical settings for all three DIP switches.
Table 3-1 defines the appropriate DIP-switch settings.

NOTE

Set positions 1, 2, and 3 of DIP-switches R, G, and B as described in
Table 3-1. Position 4 on each of the three DIP switches is not used.

This DIP

switch is

not used.

3.2 Installing the System Cables

The system cable you received with each remote unit ordered is a single 4-pair
CAT5 UTP cable with two RJ-45 male connectors attached at each end, as shown in
Figure 3-2. One system cable connects each remote unit to each system port on the
central unit’s rear panel.

remote units #2, #3, and #4, respectively.

3.3 Installing the Screen Cable

The screen cable has a DB15 HD male connector attached at one end, and a DB15
HD female connector attached at the other end. It connects the 2- or 4-Port CAT5
VGA Video Splitter central unit to the CPU.

Or, you can link a display screen to the CPU by connecting the display screen to
the screen out port on the central unit’s rear panel. You can also connect a
keyboard and mouse to the CPU, which lets you update the data display on each
remote display screen.
