GPIB to Parallel Digital Interface Board

● Provides a user-definable, 128-line parallel interface with bit, byte, pulse, string and binary data transfer capabilities. Fully configurable to the user's needs by bus commands.
● High-current drivers and input pullup resistors. Drives more devices, longer lines and inputs CMOS signals or switch contacts.
● Two companion Relay Driver Boards drive 5-48 volt relays. Boosts drive signals to control larger relays and solenoids.
● Companion expansion board adds another 128 I/O lines. Expanded configuration provides 256 I/O lines.
● Device configuration, user's IDN message and bus address stored in Flash. User can easily customize the 4813 configuration as part of his system.
● New Pulse Commands. Extends the 4813 to control latching relays and other pulse applications.

The Model 4813 GPIB <-> Digital Interface Board is an IEEE-488.2/GPIB to digital interface with 128 I/O lines that can be used to easily adapt devices with a large number of digital signals to the IEEE-488/GPIB/HP-IP bus. In a typical application, the ICS Digital Interface Board 4813 is located inside a device or test chassis and is powered by the device's +5 volt power. All digital signal connections are on a 150-pin connector at one end of the card. A 26-pin header on the other end of the ICS Digital Interface Board 4813 contains the GPIB and address switch input signals. It connects to a companion GPIB Connector/Address Switch Board that mounts on the rear panel of the chassis.

 

The ICS Digital Interface Board 4813's high-power TTL type signals can easily drive small relays or other logic elements. Applications include controlling switching matrices, displays or large signal arrays. Use with a ICS Digital Interface Board 4813 Relay Driver Board to drive high current or high-voltage relays. An Expansion Board adds an additional 128 lines letting the user control up to 256 I/O lines from the GPIB bus.

GPIB Capabilities
IEEE 488 Bus Interface
The 4813's 488 Bus interface meets IEEE STD 488.1-1987 and has the following capabilities:
SH1, AH1, T6, L4, SR1, PP0, DC1, RL0, DT1, C0 and E2 drivers.
Address Capability
Primary address range: 0-30.
Dual primary addresses or single primary with secondary addresses 0 and 1 for transparent data transfer.
SRQ Generation SRQs are generated if the unit is not a talker, if SRQs are enabled and if an Enabled Event Status Register bit or if a monitored digital input change occurs. Digital inputs monitored by the Questionable registers.
488.2 Common Commands *CLS, *ESE, *ESE?, *ESR?, *IDN?, *OPC, *OPC?, *RCL, *RST, *SAV, *SRE, *SRE?, *STB, TST? and *WAI
SCPI Commands Used to set and query all programmable functions. The 4813 conforms to SCPI 1994.0 Specification.
Interface Specifications
Signal Characteristics The 4813's parallel I/O signals have the following electrical characteristics. All time delays listed here are maximums, all pulse widths are minimums.
Inputs 128 Digital I/O lines (256 lines with expansion Bd), 2 Status and Reset Inputs
Input Logic Levels
High = > +2.0 V @ ±10 μA
Low = <0.8 V @ 250 μA
with 33 KΩ pullup to +5 VDC for sensing contacts.
Max high input = 5.5 V
Input Timing External Data Inhibit line SETS within 1 μs of the active edge of the EDR Input signal and resets after data is loaded. Data loading time for 6 BCD/HEX characters is 0.15 ms (typ.) after the 4813 has been addressed as a Talker
Output Logic Levels
High = >3 V with 3 mA source
High =>2 V with 24 mA source
Low = 0.0 to +0.55 Vdc, 48 mA sink
Output Timing Data is transferred to the output 0.6 to 8 ms after receipt of a terminator depending upon transfer method and command.
Pulse Widt
10 to 30000 ms in 10 ms steps
50 ms default
Data Stb Output pulse width, 2-5 μs
Trigger Output pulse width, 5 μs
Remote Output level asserted when in the remote state
Reset Output pulse width, 270 μs for when 4813 reset.
Reset Inputs The 4813 is reset by a low going pulse on the External Reset input line or by pressing a miniature push-button on front edge of the 4813's PCB.
