Onity HT24W / HT28 Smart Hardware • 83
The on-line reader acts as a switch to control an electrical locking device, such as an
electric strike, magnetic lock, automatic door, or gate operator. If the locking device
requires 12VDC power, and draws less than one Amp of current, the internal power
supply of the reader control unit may be used to power the locking device.
The on-line reader has a much larger capacity for data than the stand-alone locks.
The on-line reader can recognize the codes for up to 8000 rooms and masters, and
will store the last 8000 openings. If communication with the front desk console is
interrupted, the on-line controller continues operating normally with the last access
data received from the front desk console. Once communications are restored, the
front desk console will update the on-line reader with any changes made during the
interruption.
The on-line reader has a feature called anti-passback. This feature allows connection
of a second reader to the controller. The second reader is used to record exits. Anti-
passback only allows cards to re-enter an area if the card was used to exit the area.
As an example, if an on-line reader was used to control the gates in a parking deck,
users may freely enter the deck the first time. Once they use their card to exit the
deck, they may re-enter at a later time. However, if they were to enter the deck, then
give the card to a friend to allow them to park in the deck, the card will not allow the
second entry, because no exit has been recorded. This feature is optional; it is not
active unless requested at the time of setup.
Encoders
Encoders are used to create working guestroom and master cards for your Onity
locks. They can operate with a Property Management system or directly from the
software. There are several varieties of encoder available from Onity, each with
different features, but they all serve the same basic purpose.
HT22 Encoder
The HT22i insertion encoder is a single-track manual insertion encoder. No
information can be encoded on track 1 or 2. When used with the HT24W/HT28
system, the HT22i insertion encoder is controlled directly by a PC or through
HTCOM in a PMS network. In addition, the HT22i can use the onboard display and
keypad to function as a terminal on the HTCOM network. From an HT22i in
terminal mode, users can create new keys and perform other transactions directly
with only one PC acting as the server. Refer to the section of this manual about
Terminals for details.
The HT22M has an internal 3-track motorized encoding deck with integrated smart
card encoder. This deck is capable of encoding HICO, LOCO, and Smart cards.
This encoder can encode information on all 3 tracks of a magnetic stripe card when
connected to the PC based system.
HT22 Display and keypad
The display on the HT22 encoder provides instructions and messages to the front
desk operator. The eight-line display is back-lit when messages are displayed for
easy viewing. The characters on the display can be made lighter or darker by
adjusting the contrast knob under the left rear ledge of the unit.
