EMI/RFI WARNING
Thisequipment generates, uses,and can radiateradio frequency energyand,if not
installedandusedinaccordancewiththeinstructionmanual,maycauseinterference
to radio communications. The Model 4863 and 2363 have been tested and found
to comply with the limits for a Class A computing device pursuant to Subpart J of
Part15 oftheFCCRulesand tocomplywiththeEEC StandardsEN55022andEN
50082-1, which are designed to provide reasonable protection against such
interference when operated in a commercial environment. Operation of this
equipment in a residential area is likely to cause interference, in which case the
user, at his own expense, will be required to take whatever measures may be
required to correct the interference.

General Information
1.1 INTRODUCTION
This section provides specifications for ICS's Models 4863 and 2363
Parallel Digital Interface Modules. All specifications and functional
descriptions apply to both units unless stated otherwise.
1.2 DESCRIPTION
The Model 4863 GPIB <-> Parallel Interface is an IEEE 488.2/GPIB/HP-
IB compatible device that provides digital signals to drive external devices
and to input digital data onto the GPIB bus from external devices. The
Model 2363 Serial <-> Parallel Interface provides the same digital I/O
capability and GPIB functionality but with RS-232 and RS-422/RS-485
serial interfaces.
Both modules provide 48 programmable digital lines with TTL levels for
controlling devices or for data transfer. The digital interface is user
configurableintogatedinputsand/orlatchedoutputsineightbitincrements.
As inputs, each data line has a pullup resistor for sensing contact closures
or for interfacing with CMOS signals. As outputs, each line can source 24
mA or sink up to 48 mA. The interfaces can also monitor 15 of the digital
linesandreport any changestothe Bus Controller. The 4863transfers data
either as the parameter in a command or as a transparent data string. Data
can be formatted as decimal or hex characters or unformatted binary bytes.
Applications include interfacing devices with parallel digital interfaces to
theGPIBbusortoseriallinks,controllingdiscretedevices,readingthestate
of external switches or signals, and monitoring digital events.

Handshake lines are provided for transferring data to external devices and
for inputting data. Other control lines include a Remote line for enabling
external controls, and Trigger, Clear and Reset pulse outputs.
The 4863 and 2363 uses SCPI commands (Standard Commands for
ProgrammableInstruments)tosettheirconfigurationparametersandaddress.
The configuration settings can be retained in nonvolatile memory and
recalledautomaticallyatpowerturn-on. Thismeansthattheunithastoonly
beconfiguredonceandthenleftaloneuntilusedinanotherapplication. The
SCPI commands can also be used to query the current parameter settings.
Refer to the appendix for additional information about SCPI commands.
At power turn-on, the modules perform a self test of their internal logic. At
theendoftheselftest,theymomentarilydisplaytheirGPIBorserialaddress
by blinking the front panel LEDs before displaying their normal Power-on
- Ready condition.
The 4863 is a member of ICS's Minibox product family and is packaged in
asmallmetalcasethatislessthan1U(1.6 inches)inheight. Thefrontpanel
contains the power switch and LEDs which indicate the unit's status. The
rear panel contains the GPIB connector, the Relay Contact/Digital Input
connector and a DC power jack. The 4863 accepts a wide range of DC
voltages and is shipped with an AC adapter for the local power lines.
TheModel2363issimilartotheModel4863exceptthattheGPIBconnector
on the rear panel has been replaced with a connector that contains the RS-
232 and RS-485 serial signals. Because of the nature of the serial interface,
the2363onlytransfersformatteddataasacommandparameteranddoesnot
have the 4863's transparent or binary data transfer capability. The 2363 are
network capable and up to sixteen 2363s can operate on an single RS-485
network. All of the 4863's functional descriptions apply to the 2363 unless
otherwise stated.

1.3.2 OEM Board Part Numbers and Configurations
OEMBoardversionsofthe4863and2363areavailableintheconfigurations
shown in Table 1-1. On OEM Boards, the GPIB connector is a vertical
header that mates with one of ICS's GPIB Connector/Address Switch
Assemblies which may be used to mount an Address Switch and a GPIB
Connector on the user's rear panel. (See Appendix A) An LED header is
provided toremote the LEDsand thepowerswitch isremoved. Aseparate
header is provided for the optional serial interface. The Digital I/O
connectorremainsthesame. RefertoFigure1-6fortheOEMBoardlayout.
Most of the options listed in paragraph 1.3.1 can be applied to the board
product by adding the dash number after the part number.
e.g. 114504-11-7 specifies a 114504-11 Board with a custom program.

1.4 IEEE 488 INTERFACE
1.4.1 488.1 Capabilities
The4863's488BusinterfacemeetstheIEEESTD488.1-1987standardand
has the following capabilities:
SH1, AH1, T6, L4, SR1, PP0, DC1, RL0, DT1, C0 and E2 drivers.
1.4.2 GPIB Addressing
The 4863 has three, user selectable address modes. In the Single address
mode, the 4863 responds to a single primary address for all commands. In
the Dual mode, the 4863 responds to two consecutive primary addresses.
The lower address is used for commands and setting the device's address,
the upper address is used for transparent data transfer. In the Secondary
addressmode,the4863respondstoasingleprimaryaddressandsecondary
addresses 00 and 01. The lower address is used for commands, the upper
address is used for transparent data transfer. Valid primary addresses are
0 to 29 for the Dual address mode, 0 to 30 for the other modes.
1.4.3 Serial Poll Responses and SRQ Generation
The 4863's Serial Poll Responses and SRQ generation uses an IEEE-488.2
type reporting structure that has been enhanced by the addition of
Questionable and Conditional Registers for reporting the digital input
signal status and monitoring signal changes. The enhancement conforms
to the SCPI 1995.0 Specification.
1.4.4 488.2 Common Commands
The4863conformstoIEEESTD488.2-1987andrespondstothefollowing
488.2 commands:
*CLS, *ESE, *ESE?, *ESR?, *IDN?, *OPC, *OPC?, *PSC, *PSC?,
*RCL, *RST, *SAV, *SRE, *SRE?, *STB, *TRG, *TST?, and
*WAI.
