DATE OUTPUT.- Serie format, type RS-232 or RS-422, selectable
by internal jumper. Transmission rate is 1200 Bauds.
INPUT.- The input accepts six digits in BCD parallel code (1, 2,
4, 8) minus sign and six decimal points.
HOLD.- One pin is available to achieve function HOLD, in each
one of the digits, plus other pin for sign. This function allows the
user to multiplex the data inputs. If this function is not activated,
the interface unit transmits in a continuous way the BCD codes
which are presents in data input.
The logic level by default is 0 and this function is activated when
a logic level 1 is reached.
TEST (LT).- This function is activated when pin LT is linked to
level logic 0 (GND). Numerical characters sent are -8.8.8.8.8.8.
BLANKING (BI).- This function is activated when pin BI is
connected to level logic 0 (GND), in the output appears a string
of blank characters. If the output is connected to a display it will
switch off.
DECIMAL POINTS.- Until six decimal points can be controlled by
the data inputs or by the wiring in the input connectors.
MULTIPLEX.- A multiplexed system can be achieved, using only
one BCD parallel code, connecting all the parallel inputs and
operating with function HOLD, to select the digit corresponding
to the one sent it, by the BCD parallel code.
POLARITY.- With logic level 0, the sign is activated and it is
switched off when a logic level 1 is applied.
CONNECTORS.- Two 25 pins Sub-D male connectors, for BCD
data inputs.
One 9 pins Sub-D female connector, for the Serial data outputs.
One push-in cable connector, for Power Supply.
