Figure 3-1 HX.PTP-GM02 diagram
On the front surface, a 3-color LED is used to indicate the operational status
of the device, as described in Table 3-1.
Four suction cups are screwed into the corners on the back side. These
suction cups can be easily pressed to mount the device onto a clean smooth
window glass.
Three signal ports and a dip switch are placed on the front panel of the
device, as shown in Figure 3-2. Two LEDs within the Ethernet port are used to
indicate the status of the electrical Ethernet connection, while the LEDs along the
optical port indicate the status of the optical Ethernet. Descriptions of these ports
