4813
GPIB to Parallel DigitalInterface 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.
Details
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 |
| ||
| Address Capability |
| ||
| 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 |
| ||||
| 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 |
| ||||
| 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 |
| ||||
| 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. |
