Parallel Interface
Standard 4803DVR supplies a male DIN
connector for mounting a 2003, 2303, 4803
or 8003 Interface Board with its Digital I/O
connector on the circuit side. Power supplied
by a switching power supply on the 4803DVR
board.
Supplied Power:
Voltage
+5 ± 0.2 Vdc
Current
500 mA max
Companion Interface Boards
The Standard 4803DVR board supports the
following ICS small Interface Boards:

4803DVR Connections
The following companion Interface Board
lines are used by the 4803DVR Board:
40 Digital I/O lines
Stable Signal
External Reset Input
Other Interface Board Signals
The following companion Interface board
signals are brought to pads on the 4803DVR
Board and are available to the user:
LED drive signals:
PWR, RDY, TALK, LSTN, SRQ
and ERR
EDR and Inhibit pairs #1 and #2
Status A and Status B inputs
Trigger, Remote and Reset outputs
Data Strobe
4803DVR: Specifi cations
Driver Characteristics
High power outputs for driving relays or
other loads. Relay driver outputs controlled by
SOURce or ROUTe commands with polarity
set to high true. Number of lines is 40 less the
number of lines that by-pass the relay drivers
and connect directly to ports 1 and 2 on the
digital board.
Number
24, 32 or 40 Lines
Driver Form Open collector with
anti-backlash diode.
Current
up to 300 mA
Vout low
1.3 volts at 300 mA
V max
32 Vdc
TTL Signal Characteristics
TTL signals have the same characteristics as
the companion Interface Board's digital signals.
Inputs typically have 33 Kohm pullups for
sensing CMOS signals and contact closures.
Outputs sink up to 48 mA. Signals controllable
by Interface Board commands or are monitored
by the Questionable Register.
Number
16, 8 or none
As inputs:
High
> 2.4 Vdc or open
Low
< 0.5 Vdc at 200 µA
Pullup resistor 33 kohms to +5 Vdc
As outputs
High = >3 V with 3 mA source
High =>2 V with 24 mA source
Low = 0.0 to +0.55 Vdc, 48 mA sink
External Reset Input
TTL input signal that resets the Interface
Board when pulled to ground. Pullup pro-
vided by a resistor on the companion Interface
Board.
