Drives more devices, longer lines and inputs CMOS signals or switch contacts. ● Device configuration and bus address stored in Flash. Saves your setup values. ● IEEE-488.2 compatible unit uses SCPI commands and Short Form commands. Includes latest GPIB program advances. ● Packaged in small 1U high metal case. Smaller size with EMI/RFI protection. ● Includes a menu-driven configuration program. Steps user through configuration choices.
The 4863 is an IEEE-488/GPIB/HP-IB to Digital Interface that provides 48 programmable digital lines that can be configured as inputs or outputs in eight bit bytes. Each data line has a pullup resistor for sensing contact closures or TTL/CMOS inputs. As outputs, each line is latched and can source 24 mA or sink up to 48 mA. The ICS Digital Interface 4863 can also be configured to monitor up to 15 input lines for changes. Applications include interfacing devices with parallel digital signals to the GPIB bus, controlling discrete devices from the GPIB bus, monitoring digital signals for changes and outputting blocks of data.
ICS Digital Interface 4863 is a member of ICS’s Minibox™ interface family. All Minibox™ interfaces are IEEE 488.2 compatible, use SCPI commands for ease of programming and are packaged in a CE compliant metal case that is less than 1.6 inches (39 mm) high. Rack mounting kits are available for mounting one or two Model 4863s in a single 1U high space.
The 4863's 488 Bus interface meets IEEE STD 488.1-1987 and has the following capabilities:
SH1, AH1, T6, L4, SR1, PP0, DC1,
RL1, DT1, C0 and E1/E2 drivers.
Address Capability
Dual primary addresses or single primary with secondary addresses 00 and 01. Primary address range: 0-30.
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 an monitored digital input change occurs. Digital inputs monitored
by the Questionable registers.
Used to set and query all programmable functions. The 4863 conforms to SCPI 1995.0 Specification.
Digital Lines
The 4863's parallel I/O signals have the following electrical characteristics. All time delays listed here are maximums, all pulse widths are minimums.
Lines
48 Digital I/O plus
2 Status Inputs
Input Logic Levels
High = > +2.0 V @ ±10 μA
Low = <0.8 V @ 250 μA
with 33 Kohm pullup to +5 VDC for sensing contacts.
Max High = 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 4863 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 5.3 ms after receipt of a terminator depending upon transfer method.
