A good power source is very important. The TDAS WET should be powered from a
fully-charged 12 V battery or high-quality 12 V power source. When assessing power
requirements, please consider any voltage drops that may occur due to cables,
connectors, power converters, etc.
COM A and COM B Connectors
Ethernet 10/100BaseT communications, event input, start record input, and status
output signals are supported via these connectors. These connectors are functionally
identical and are compatible with all TDAS COM connectors.
WARNING:
Do not apply external voltages to the communication output
and inputs—this could result in damage to the unit.
Push-button Switch (POWER)
To power-up the unit, connect sufficient power to the power input
connector and press the push-button switch for 5 seconds. Power-up is
immediate after which the unit will log into the network.
To power-down the unit, press and hold the push-button switch for
3 seconds or until the POWER LED goes dark.

This LED indicator is green, blinking, or off. A green LED indicates the unit has
connected to the wireless access point (WAP). The LED blinks when data is trans-
mitted. If the LED is off, the unit has not connected to the WAP and troubleshooting is
required.
