5.7. CON7/CON8 (Power Input Connector)
CON7 is a DC jack that supplies power to the Armadillo-210 and CON8 is a 2-pin connector that supplies
power to the Armadillo-210.
The input voltage range is DC9V to 48V. The AC adapter jack is 5.5mm in circumference and 2.1mm in pin
hole. Those AC adapters having the same polarity mark as shown in Figure 5-2 can be used.
In addition to the power input from the DC jack or the CON8, the Armadillo-210 can support Power over
Ethernet*.
Power over Ethernet (IEEE802.3af) is the standard for a system to supply electrical power to remote devices over
standard LAN cable.
Note 1: If an AC adapter with high-voltage specification exceeding 12V is used, a high-voltage spark can
generate at the contact part when a plug is connected to the Armadillo-210. Therefore, be sure to first
connect the Armadillo-210 to the AC adapter and then connect the AC adapter to the outlet.
Note 2: If power has been restored to the Armadillo-210 in a very short time interval, it may keep in reset mode
and not boot up. Therefore, be sure to leave over 30 milliseconds before restoring power.

5.8. CON9 (Power Output)
CON9 is an external output power connector. It outputs power from the AC adapter or the Power over
Ethernet. Output voltage is determined according to the supplied power voltage.
- When using an AC adapter, total consumption current of Armadillo-210 must be less than 800
ｍ
A.
- When using Power over Ethernet, total power consumption of Armadillo-210 must be less than 12.95W.
(Standard power consumption of the Armadillo-210 main body is approx. 1.2W).
- Depending on operational environments, the Armadillo-210 could not be operational even if it was used
below maximum rating. Be careful about this when using the Armadillo-210.
