MODEL V732

DATA IN Indicator
The DATA IN LED indicates the level of the data being input
to the V732 over copper. A green LED indicates a logic
HIGH is present on the copper inputs. A yellow indication
indicates a logic LOW is present on the copper. No color
(OFF) indicates a tri-state or high impedance input. This
can therefore be used to determine the resting state of your
equipment and, in the RS-485 state, verify that a tri-state is
being detected properly. The V732 has special circuitry to
capture data transitions and make them visible on the
LEDs. High-speed bursts of activity, previously unde-
tectable by standard LED circuits, can easily be seen by
this special circuitry.
DATA OUT Indicator
The DATA OUT LED functions identically to the DATA IN
LED except that the LED represents data that is being out-
put from the unit. This LED has the same high-speed cap-
ture circuitry described in the DATA IN section.
