Guidelines
Mini-touch panels require 12 VDC power to operate properly. The AXCESS Control
System supplies power via the AXlink cable. The maximum wiring distance between
the control system and mini-touch panel is determined by power consumption,
supplied voltage, and the wire gauge used for the cable. Figure 15 lists wire sizes
and the maximum lengths allowable between the mini-touch panel and control
system. The maximum wiring lengths for using AXlink power are based on a
minimum of 13.5 volts available at the control system’s power supply.

If you install the mini-touch panel farther away from the control system than
recommended in Figure 15, connect a 12 VDC power supply to the TiltScreen,
UniMount, and rack-mount mini-touch panels according to the wiring diagrams and
pinout descriptions in this section.

Caution
Do not connect power to the
mini-touch panel until the wiring
is complete. If you are using a
12 VDC power supply, apply
power to the mini-touch panel
only after installation is
complete.
