General Information
1.1 INTRODUCTION
This section provides specifications for ICS's Models 4807 and 2307 Data
AcquisitionandControlBoardsandModels4867and2367DataAcquisition
and Control Modules. All specifications and functional descriptions apply
equally to both types of units unless otherwise stated.
1.2 DESCRIPTION
1.2.1 All Units
All units covered by this manual provide the same analog and digital
interface that contains digital and analog signals to control external devices
and input digital data, analog voltages and temperature readings from
external devices.
The analog section of the interface provides four analog outputs, six analog
inputsandfour thermocoupleinputs. Theanalogoutputs areprogrammable
over a 0 to 5 Vdc range. The analog inputs are single-ended inputs with
programmable ranges of ±10, ±5, 0 to 5 and 0 to 10 Vdc. The thermocouple
inputs accept type J thermocouples and can read temperatures from -100 °C
to + 400 °C.
The parallel digital interface provides 32 programmable digital lines with
TTL levels for controlling devices or for inputting digital data. The digital
interface is user configurable into gated inputs and/or latched outputs in
increments of eight bits. As inputs, each data line has a pullup resistor for
sensing contact closures or for interfacing with CMOS signals. As outputs,

1-2
1
each line can source up to 24 mA or sink up to 48 mA. The boards can also
monitor 15 of the digital lines and interrupt the system controller when a
change occurs.
The units also provide six relay driver outputs that can be used to actuate
external solenoids, drive relays or operate any device requiring a high sink
current.
All units use SCPI and/or short form commands to set their configuration
parameters, transfer data, operate the control lines, take measurements and
to set its address. All settings are retained in nonvolatile Flash memory and
are recalled at power turn-on or when the unit is reset. This means that the
unit has to only be configured once until used in another application. The
SCPI and short form commands can also be used to query the current
parametersettingsandallinputsignals. SCPIstandsforStandardCommands
for Programmable Instruments. Refer to the appendix for additional
information about SCPI commands.
At power turn-on, the units perform a self test of their internal logic. At the
end of the self test, the units displays their address by momentarily blinking
the address on its LEDs before displaying the normal Power-on - Ready
condition.
1.2.2 Board Units
The Model 4807 and 2307 DAQ and Control Boards are small 4.5 x 5.5 inch
PCBassembliesthat arepoweredfrom5 Vdc. Theanaloganddigital signals
are on a right-angle metal shell connector with lock studs for secure signal
connections in any application. The Model 4807 has an GPIB/IEEE-488.2
compatibleinterfaceanda headerforconnectiontoan ICS GPIBConnector/
Address Switch Assembly. The Model 2307 has RS-232/RS-422/RS-485
compatible serial interfaces on a right-angle 9-pin DE connector for direct
connection to a serial link. Both boards are designed to be installed
internally in a piece of equipment and to be shielded by the host equipment's
case.
The 2307 may be controlled over an RS-232 or RS-422/RS-485 point-to-
point data link in which case it does not need or use an address. The 2307
can also operate on a multidrop RS-422 or RS-485 network, when address
mode is enabled. In this case the 2307 can be enabled to recognize an

1-3
1
address string prefixed to the SCPI commands and only responds to those
commands with an address that matches the one stored in its Flash memory.
For secure applications, the 2307 can be set to operate in a packet mode
where the commands and responses are encoded in a packet with a
checksum. In this case, the 2307 only executes commands in valid packets
that contain the board's address.
1.2.3 Modules
The Model 4867 and 2367 DAQ and Control Modules are packaged in
ICS's Minibox case and are powered by a companion wall mounted AC
power adapter. The analog and digital signals are on a right-angle metal
shell connector with lock studs for secure signal connections in any
application. TheModel4867hasanGPIB/IEEE-488.2compatibleinterface
and a standard GPIB connector for connection to an IEEE-488 Bus. The
Model 2367 has RS-232/RS-422/RS-485 compatible serial interfaces on a
right-angle 25-pin DB connector for direct connection to a serial link. Both
modules are designed for stand-alone use or for mounting in a rack mount
kit.
The 2367 may be controlled over an RS-232 or RS-422/RS-485 serial link
as described above for the Model 2307.
1.2.4 OEM Boards
The PC Board Assemblies from the 4867 and 2367 Modules are available
as OEM PCB Assemblies. These PCB Assemblies are available with just
GPIB or Serial interfaces or with both GPIB and Serial interfaces.
P/N 115097-01 GPIB Interface
P/N 115097-02 Serial Interface
P/N 115097-03 GPIB and Serial Interface
The OEM Board Assemblies have 0.187 inch high standoffs for mounding
against a metal plate.

1.5.5 RS-232 Transmission Protocol
1.5.5.1 Echos and Prompts
The 2307 and 2367 returns a prompt when ready for the next command. If
Echo is enabled, the prompt character is lined along the left edge of the
screen. The CNTL-E and CNTL-F commands turn echo on and off and
change the prompt sequence and message terminators as follows:
Command Echo Message Terminator Prompt
CNTL-E On Response CR LF CR LF >
CNTL-F Off Response LF > LF
The user should not attempt to send a new command until it has completed
the current command. Echo mode changes are immediate.
1.5.5.2 Service Request Message (SRM)
The 2307 and 2367 emulate the IEEE-488.1 SRQ line by transmitting an
asynchronous Service Request Message (SRM) when it is not busy
processingamessage andwhenan enabled StatusBytebit becomes set. The
SRM format is:
SRM n <LF> where n is the decimal value of the Status
Byte Register
e.g. SRM 96 indicates bits 5 and 6 are on.
1.5.6 RS-422/RS-485 Basic Protocol
When the Network mode is set to Off, the RS-422 interface operates as does
theRS-232interfacewithEchoOFF. Allresponsesmessages are terminated
with a linefeed character (LF). A '> LF' prompt is sent after each command
or after the response message. The transmitter is enabled until the prompt
is sent. SRM messages are sent when enabled.
1.5.7 RS-422/RS-485 Network Address Protocol
When Network Address is enabled, the first two characters of each received
message are checked for an address character that matches the address set
in the unit's Flash memory. If a valid address is detected, then the unit
responds to the command or query as it would normally. The Address

1-8
1
character sequence is an STX character (02) followed by the address
character. The address character is the ASCII number with a hex value of
30 - 3F. An example is the IDN query sent to a 2307 at address 4.
i.e. STX 4 * I D N ? (LF)
Promptsaresupportedwhennetwork addressing isenabled. Thetransmitter
is enabled until the prompt is sent. SRM messages are inhibited when
Network Address is selected
1.5.8 RS-422/RS-485 Packet Protocol
When Network Packet protocol is enabled, the unit operates with serial
packets that contain the commands, queries and responses. The unit
responds to packets containing an address character that matches the
address set in the Flash memory. If the checksum and command is valid,
the command is executed and an ACK packet is returned. If the checksum
or command is invalid, a NAK response is returned. ACK/NAK command
response packets contain the current ESR Register value.
The general packet format is:
STX Addr Message Characters....ETX Checksum
An acknowledgment packet is:
ACK Addr ESR_Register_Value ETX Checksum
ACK Addr Query_response ETX Checksum
An NAK packet is:
NAK Addr ESR_Register_Value ETX Checksum
Where:
ASCII characters 0 to 1F hex are reserved for message control.
ASCII characters 20-7F are for address and data.
Address character is 30-3F hex.
STX is ASCII character 02 hex.
ETX is ASCII character 03 hex.
ACK is ASCII character 06 hex.
NAK is ASCII character 15 hex.
Checksum is the exclusive OR sum of all of the characters
from the STX character though the ETX character.

1.12 INDICATORS
The board has six diagnostic LEDs that display the following conditions:
PWR - Indicates power on.
RDY - Indicates unit has passed self test.
TALK/TX - Indicatesunit has recognizeditstalk addressor
is transmitting a serial message.
LSTN/RX - Indicates unit has recognized its listen address
or is receiving a serial message.
SRQ/SRM - Indicates unit is generating an SRQ.
ERR - Indicates unit has detected an command error
and the command was not executed or the
Flash is corrupted.
When the board is turned on, it performs an internal self test which takes
about 0.4 seconds. The PWR indicator is on during selftest. At the end of
the self test, the unit displays its current serial network address setting by
blinking a binary pattern on the LEDs. The LED bit weights are:
RDY TALK/TX LSTN/RX SRQ/SRM ERR
16 8 4 2 1
Any errors found during self test are indicated by a repeated blinking of the
error code pattern. Refer to Table 5-3 for a description of the self test errors
andtheirpossible causes. Whenallofthe LEDs excepttheERRLEDblink
on for 1 second, the unit is writing configuration parameters to the Flash
memory. When all of the LEDs blink on for 1 second, the unit is initializing
the Flash memory to factory defaults
1.13 EXTERNAL RESET INPUT
The -ExtRst is a low true input with a 33 Kohm pullup that is used to reset
the unit. The unit is held in the reset state while -ExtRst is low.
