The green light (2) is illuminated when the encoder is waiting for a card

will go out.
The other red light (3) is illuminated when the encoder returns the card
after finishing a read and/or write operation.
• Switches
The red power setting switch (7) is used to select the type of power that
is being supplied at the site; either 115VAC or 220VAC. Installations
within the United States will use the 115VAC setting. For information
about the power supplied to your property, please contact your local
electric utility company.
The Power switch on the back of the unit (11) is used to turn power to
the unit on or off. Inside the switch housing is a small compartment that
contains the main power fuse and one spare.
If you have the High Coercivity model, the encoding mode selector
switch (12) is used to select either High Coercivity or Low Coercivity
encoding. High Coercivity encoding uses either 2750 Oersted or 4000
Oersted magnetic stripe cards. Low Coercivity encoding uses 300
Oersted magnetic stripe cards.
• HT24+ Connections
The DB9 connectors (9 and 10) are used to connect the encoder to the
communication distributor through the HTCOM network.
