series. The original version of this Tibbit required 5V power to be connected to the
IO line 3. On the new Tibbit #08 of the
revision B
, line IO3 is connected to the
internal 5V power (the diagram above shows this modification in
red color
). This
modification spares you from the necessity to provide external power for pull-ups.
You can even use IO3 line to power your reader (if the reader can run on 5V and
your TPS system has enough spare power).
Revision B
devices are marked by a
small round sticker with letter "B". The sticker is on the side of the Tibbit.
Tibbit #08 has a standalone open collector output controlled through LINE D. Set
LINE D LOW to open the transistor. When left unconnected, the line defaults to
HIGH (hence, the transistor is closed).
Combine this Tibbit with terminal block devices --
(four terminal blocks). Note that #21 doesn't provide the ground line, and using this
Tibbit requires the ground line between the reader and your system. Hence, if you
use Tibbit #21 you will need to "steal" the ground somewhere else.
Check out the Tibbit
(four open collector outputs) if you are looking to
emulate
clock/data or Wiegand reader output (that is, of you want to turn your device into
a reader that outputs data).
LEDs
There are four LEDs: two red and two green. Red LEDs are connected to the
CONTROL and OC line. Green LEDs are connected to W0&1 and W1 lines. All LEDs
are buffered (with logic gates) and light up for the LOW state of control lines.
