the corresponding outputs on the interface.
While typing you should hear a "beep" emitted by the
buzzer, and should see the green LED LV turn on briefly.
Verify that by powering on the interface you receive the
proper LED ignition sequence L1, L2, A, B, C, D.
Check that, with the keyboards connected to and
memorized on the interface, the green interface LED
L1 flashes quickly, and that the red LED L2 remains off
(communication with keyboards is without errors).
Make sure the white backlight LEDs are dimmed when
the keyboard is idle, and that upon pressing a button, it
brightens up.

Maintenance
Perform scheduled maintenance every 6 months by
checking the state of cleanliness and operation of the
device, as indicated in paragraph 9 Testing).

Keypad functionality for access control
Description of the terminals (Figure 8):
1 Positive of the power supply, 12Vdc o 24Vdc (*)
2 COM, negative of the power supply
3,4 Not available
5 for ISO2: CLS, "Card Loading Signal" enabling line.
6 for ISO2: RCP, "Read Clock Pulse" clock signal;
for Wiegand: DATA1
7 for ISO2: RDP, "Read Data Pulse" data line;
for Wiegand: DATA0
(*) The power supply must be continuous; reverse polarity
will activate keypad protection
NOTE: signals CLS, RCP and RDP or DATA0 and DATA1 are
digital signals ranging from 0 Vdc to 5 Vdc.
If the keypad is configured to send channel information (keys
1/A, 4/B, 7/C, */D), after entering the user code followed by
the star key *, the LV green LED lights up. At this point, the
channel key can be pressed, thus sending the code to access
control (the LR red LED comes on for a second signaling the
transmission). Then, other channel keys can be activated,
provided that no more than 5 seconds elapse between one
activation and another. Otherwise code transmission mode
is exited, the buzzer sounds, and the LV green LED goes out.
If the keypad is configured to not send channel information,
the user code followed by the star key * immediately
activates message transmission to access control; a one
second flash of the LR red LED indicates that transmission
has occurred and the keypad is ready for another entry.

Operating mode selection

The H85 / TTD touch keypad has a 3-way dip-switch to
select specific operating modes for communication with
access control systems:

The Wiegand modes (26-bit, 37-bit, 50-bit) and ISO2
("magnetic stripe") are standard communication protocols
used by access control manufacturers, and allow choice
over the format of numeric data to be transmitted.
To entered user code information can be added:
• information relating to the "site code", a numeric
code that distinguishes a particular installation,
which is customizable: by typing the same user code
on two keypads with different site codes a different
transmission is obtained
• the information on the activated channel key (1/A, 4/B,
7/C, */D), for example, to identify a door that must be
open
Communication according to the Wiegand protocol (3-
wire) is realized by connecting the DATA0, DATA1 and COM
terminals to the access control system.
Communication according to the ISO2 protocol (4-
wire), with encoding format ABA-TRACK, is realized, in
compliance with ISO-3554, by connecting the CLS, RCP,
RDP and COM terminals.
For both protocols, the signals go out live, with values 0Vdc
(transistor forced) or 5Vdc (via resistance of 2k7 pull-up),
so more than one keypad cannot be connected to the
access control.
12.2
Wiegand communication mode
The functions available are "Code activation" and "Change
password". Here, "password" denotes "site code" and as
factory standard the initial site code is "0000".
Therefore, to change the site code follow the password
change procedure, which also allows enabling or disabling
of the transmission of channel information.
If the password (site code) change procedure is followed
by the star key * instead of the # key, in addition to site
information, the transmission of channel information is
enabled (see table in paragraph 12.1, column "INFO CH ").
Example:
to set the site code to 1234 and enable the transmission of
channel information, enter the following sequence:
* * <old site code> # <1234> # <1234> *
NOTE: there is a maximum number of bits that can be
assigned to the binary code (indicated in brackets). If this
is exceeded, an error message is returned with 5 quick
flashes of the LR red LED, accompanied by a buzzer sound.
