LOGIC TRUE SELECTION
be compatible with the logic convention of the output device (programmable
controller, etc.). DIP switch A (SWA) has two switch positions which provide
pull-up (SNK) or pull-down (SRC) resistors on all Data and Strobe inputs.
Position 1 and 2 of DIP switch B (SWB) select the logic true state of the “DATA”
and “STROBE” inputs. A “0” logic true level for the “STROBE” lines indicates
that it is necessary to pull the “STROBE” lines low to allow the data to be strobed
in and displayed. A “0” logic true level for the “DATA” inputs indicate that to
activate the 1, 2, 4, or 8 data inputs, they must be pulled low. For example, a 9
is entered by pulling the 1 and 8 data inputs low and strobing the digit. A “1”
logic true condition indicates that the line must be brought high to be activated.
When setting up the DIP switches to a logic true level, both “DAT” or both
“STR” switches on “SWA” and “SWB” should be in the same position (0 or 1).
NON-MULTIPLEXED (Input Following)
OPERATION
each digit is available all of the time. In this mode of operation, the strobe inputs
are set in their logic true state. When this is done the data sent to the unit will be
displayed immediately. In setting up the DIP switches for this mode, the “STR”
position on “SWA” is set opposite to the “STR” position on “SWB”. Both “DAT”
switch positions should be set to the same state depending on the logic (0 or 1).
digit/s only part of the time. This normally occurs in systems which utilize the
BCD data lines to send data to more than one digit, more than one display, or
both. For the Slave Display to function properly, the digit Strobes must be
activated when the correct information is present for the digit/s being strobed.
MULTIPLEXED (Strobed) OPERATION
lines are required, however , a separate strobe line is needed for each digit. The
four data lines are connected in parallel to each individual digit of the display/s.
lines per digit. All BCD data information is available to the Slave Display at
the same time and only one “STROBE” line is required for each Slave Display
(all “STROBE” lines are tied together).
“DAT” switch positions should be set to the same state and both “STR” switch
positions should be set the same.
CASCADING DISPLAYS
for six digit) among several Slave Displays. To accomplish this, each Slave
Display must have its data strobed in at different times which requires
multiplexed operation and a separate strobe line or lines for each display. If data
can be strobed into each display, four or six digits at a time, only one strobe line
is required for each additional unit cascaded. If only four BCD data lines are
available from the output device, they must be paralleled with the other digits and
four or six strobe lines would be required for each additional Slave Display.

The Slave Display has one 100 K

each diagram the ACA1 DIP Plug Cable Assembly parallels the BCD data
lines to the second display. Additional units can be added in a “daisy chain”
configuration by utilizing additional cable assemblies and plugging them into
the unused DIP sockets. The pin 1’s of the cable assembly must be connected
to the corresponding pin 1’s of the DIP socket.
