•
When the ignition sense line is pulled low (less than 2 V), the EXPLORER 122 Terminal
performs a controlled shutdown sequence (under software control), de-registering and
saving any relevant operational data before powering off.
•
When the ignition sense line is pulled high (5 to 30 V) or left unconnected, the EXPLORER
122 Terminal powers on.
CAUTION:
Do not apply an input voltage to the terminal outside of the
specified range. This will permanently damage your terminal.
CAUTION
: Observe proper Electro-static Discharge (ESD) practices during
installation.
The terminal protects against continuous inputs of -32 VDC to +32 VDC. Applying an input
voltage outside this range may permanently damage the terminal and cause it to become
non-operational.
2.7.2.2
Ethernet Interface
The Ethernet interface is defined by IEEE 802.3 for operation in 10Base-T and 100Base-TX
modes with the exception of the connector type. Cabling for Ethernet connectivity must
meet ANSI/TIA/EIA-568-A specifications for Category 5 or Category 5e cables. It is
recommended that the wired Ethernet interface be used for permanent installation. Contact
your terminal retailer for power/Ethernet cable or build your own cable assembly as shown
in section 6.
CAUTION
: Use an Ethernet cable length no greater than 100m (328 ft.) to
ensure proper terminal operation.
