13.5.4 Wiring Cooling Units without Wall Mount Displays
NOTE: Cooling units are factory wired for stand-alone operation. Do not connect the U2U network cabling before
setting the U2U network configuration/groups. Network communication conflicts and unreliable display readings will
result.
NOTE: Before you begin, refer to Preparing for U2U Group Set Up on page 57, and Configuring U2U Network Settings
on page 59.
To connect two cooling units with a touchscreen, a network switch is not needed:
• Connect a crossover CAT5 cable to the ETH-2 connector on the rear of each display as shown in Figure 12.19
below.
