STATINTL DESCRIPTION OF #2826A BI-DIRECTIONAL COUNTER
!STATINTL
Dwg. No. 5000-119)
The 2826A Bi-Directional Counter is a 6 digit, bi-directional totalizer which
will register the algebraic sum of the number of input pulses fed into the inputs
A and B.
_ Input requirements, Channel A and B:
Pulse, 51isec wide, +1V peak amplitude in reference to 0 volts,
rise time 11Asec or less.
Maximum Counting Rate: 100KC May be expanded to 1MC (Option).
Minimum spacing between pulses on either channel: 10?sec.
_ Preset-reset capability: From 000,000 through 999~ 999 by remote selection,
BCD 1-2-4-8 coded switches necessary. Preset voltage supply from counter.
Preset command is remote by contact closure.
Reset capability: To 000, 000, by remote contact closure.
_ Output specifications: BCD 1-2-4-8. Logic 1= -8VE2V; Logic 0=-. 5V or less
over 6. 8K series resistor. BCD output is from built-in register.
_ Storage capability: The counter has a register which will follow the counting
decades until a keying command is issued. Upon this command the information
contained in the register is being held until removal of the keying command. The
keying command is a level change from -6V - -12V to -. 5V - +6. 0 Volts. The
register store BCD coded information, not the 10 line-output to drive the remote
readout.
Readout: Remote, 10-line output to drive standard Nixie* tube.
Counting direction: Normal or reversed by external contact closure.

amplitude: 90mV Peak-to-Peak.
Input impedance: 5K ohms shunted by 30pf.
Power requirements: 115VAC ?10%, 50/60cps, 60 watts.
Dimensions: Approximately 19" x 5 1/4" x 12 1/2" (without connectors)
Rack mount, all connectors on rear panel.
Weight: Approximately 35 lbs. net.
DESCRIPTION OF #2827A SYNCHRONIZER & FORMAT OUTPUT CONTROL
Dwg. No. 5000-120)
General:
STATINTL The #2827A Synchronizer and Format Output Control accepts up to 42 digits
or characters in BCD coded form and converts these into serial form.
1. 1 Speed: 1200 letters per second ?. 001%.
1. 2 Input requirements: Up to 42 1-2-4-8 coded parallel inputs. Logic 1 equals
-4. 5 to -12 volts, logic 0 equals -. 5 volts or less into 3. 9K load.
1.3 Receive data lead (RDL): +8 ?2V for space, -8 ?2 for mark into 4. 7 K load.
1.4 Clear to send (CTS) signal: -8V ?2 for Off, +8 ?2V for On into 4. 7K load.
1.5 Interlock to transmission equipment: OV for Off, +8 ?2 for On into 4. 7K load.
1.6 Send Data Lead (SDL): +10 ?2V for space, -10 +-2 V for mark @ 2mA each.
1.7 Request to Send (RTS) signal: -8V ?2V for Off or Hold; +8 ?2V for On
or Transmission.

#2827A SYNCHRONIZER & FORMAT OUTPUT CONTROL
2. 1 In addition to the information bits to be transmitted, two pulsing bits are
generated for each character. A start pulse is a space or (0) and is the
same duration of the other bits. A stop pulse is a mark or (1) and is a
minimum of 1. 5 bits in length but may be longer.
3. 1 CODE: The code generated will meet the following requirements:
3. 2 Code to be used is Field Data Code, consisting of a 6-bit character plus
one parity bit. Parity is odd.
3. 3 The 2? or least significant information bit is the first bit to be transmitted
from each character.
3. 4 Parity is to be the 26 bit and is the last information bit of each character.
4. 1 MESSAGE GENERATED: The message generated by the Synchronizer
consists of:
4.2 Digital coordinate values for each axis of the system. This shall
normally consist of six decades plus sign per axis.
4.3 A start of message character (SOM).
4.4 An end of transmission character (EOT). (This bit configuration
would normally be a parity error).
4.5 A message parity count (MPC). This is the sum of bits of all
characters transmitted (including SOM and EOT), and is non carry add.
Lateral parity is odd. Longitudinal parity is even. The parity bit is to
be the sum of the longitudinal bits.
4.6 Four special instruction characters, each generated by four operator
controlled push on, push off back lit switches, two dummy bits (mark or 1),
and a parity bit generated by the equipment based on the condition of the
four switches. The fixed dummy bits occupy the 24 and 25 bit positions.
4. 7 A special readout character generated by five momentary contact push
button switches and two fixed dummy bits occupying the 25 and 26 bit
positions. The dummy bits are spaces or 01s. It is understood that the
parity (26) is to be fixed at 0 so that if two of the five switches are pressed
at the same time, a parity error will be detected. The five switches are
understood as readout switches and also control the request to send, SOM and
text as later described.

I# 2827A SYNCHRONIZER & FORMAT OUTPUT CONTROL
4.8 Three rotary switches are provided for machine identification purposes.
These switches are to have the capability to create 0 to 9 and are placed
at the rear panel of the synchronizer so that only the maintenance engineers
have the capability to change them.
4. 9 10 special characters, generated by remote switch setting. These switches
have the capability of producing 0 to 9, minus (-).
5.1 SPECIAL CIRCUITS: There is to be no character by character acknowledge
signal received by the digitizer output circuit. However, there is to be a
message acknowledge or error signal received on the basis of the total
message transmitted. The reply consists of SOM, A or E, EOT, and
MPC. In addition, a timer in incorporated in the equipment to trigger an
alarm if the reply is not received in a time of 3 seconds to be specified
by the customer. The output is to be held in the digitizer buffer until an
acknowledge is received or the timer alarm is triggered. If an error
signal is received due to a bad transmission, the timer is reset and
another attempt at transmission is made. If, after a set number of attempts
of retransmission (under computer control), an acknowledge or error
signal is not returned, the timer will time out. If a read-out is initiated
but no acknowledge or error signal is received, the timer will also time
out, warning the operator that the transmission is not taking place.
In addition, an indicator light is to be placed on the control panel in close
proximity to the readout switches. On depressing any one of the five
readout switches the light is to turn on and remain on for approximately one
second or until an acknowledge signal is received, which ever is longer,
This will indicate to the operator that a readout has been initiated within
the digitizer.
