INTRODUCTION
This manual explains RS-232C two-way communications function of the chroma meter
CS-100A.
In case to use the ata output function succee e from the former mo el of CS-100,
please refer to the instruction manual of CS-100A.

1
Connection to personal computer
Use RS-232C connecting cable (optional accessory LS-A12) to connect
to a personal computer.
<Caution relate to connection>
Connect the connector to the proper direction securely.
Always turn off the power of both this product and the personal computer
before carrying out the connection.
Remove the connection cord always holding the plug or the connector. And
do not pull or forcibly bend the cord.
Do not touch, stain or apply unreasonable force to the terminal part of the
connector.
Arrange the cord with extra length. If there is not sufficient extra
length, it may cause connection failure or disconnection.
<Data output terminal>
RP 7- 3RA- 2SD made
by Hirose is used
for the connector
for data output of
this product.
Connect and use RP 7-
3P- 2PC connector
made by Hirose.
Absolute maximum rating of output transistor

Each pin of igital output terminal
Pin : Ground (GND)
Pin 2: Ground (GND)
Pin 3: ---- External equipment condition signal input. Use it OPEN (Busy in)
Pin 4: RTS output
Directly connects to the CTS terminal of the personal computer at the
time of two-way communications by RS-232C.
Outputted at the voltage level of about }0V.
Pin 5: External power input
Positive electrode of power when supplying power from outside. Pin or
pin 2 is the ground. Use the power of 8 - 2 VDC, 00mA or more.
Pin 6: CTS input terminal
CTS input
Directly connects to the RTS terminal of the personal computer at the time
of two-way communications by RS-232C.
Pin 7: TxD output
Directly connects to the RxD terminal of the personal computer at the time
of two-way communications by RS-232C.
Outputted at the voltage level of about }0V.
Pin 8: Measured value serial output
Use it OPEN.
Pin 9: RxD input
Directly connects to the TxD terminal of the personal computer at the time
of two-way communications by RS-232C.
Pin 0: Synchronous clock output
Use it OPEN.
Pin : External measuring request signal input
Use it OPEN.
Pin 2: Internal supply power output
Use it OPEN.
@Pins 3,8, 0, , 2 are necessary terminals when succeeding to use the external
output function of the former model CS- 00. Use them OPEN in case to use the
RS-232C communication mode. (Refer to the instruction manual of the main body
version.)

Setting to RS-232C mode
Carry out the following settings to communicate connecting this
pro uct an a personal computer.
<Setting proce ure>
.Check the power is off.
2.Turn on the power switch with the F key of this
product kept pressed.
3.The letter of "C" is displayed in the right bottom
corner of the external display.
It is set to the RS-232C two-way communications mode.
Command list
MES : Following the mode setting, measures one time
Displays the measured value and outputs from the RS-232C terminal.
MDS : Carries out various mode settings.
CLE : Carries out the memory clear action.
RCR : Recalculates according to the mode setting and outputs the calcu-
lated result from the RS terminal.
TDR : Outputs the target value for measuring color difference memorized in
the main body from the RS terminal.
UCR : Outputs the standard value for measuring user calibration standard
memorized in the main body from the RS terminal.
TDS : Memorizes the measured value held by the main body as the target
value for measuring color difference in the main body.
TDW : Receives the target value for measuring color difference from the RS
terminal and memorizes in the main body.
UCW : Receives the standard value for measuring user calibration standard
from the RS terminal and memorizes in the main body.

Notes on RS-232C mode
EIn case to use in RS-232C two-way communications mode, it is recommended to
carry out OPEN and CLOSE of RS port before or after transmitting one command.
In case to use in RS-232C two-way communications mode, the consumption
current increases comparing to the normal use.
Especially if connected with the RS port of the personal computer side OPEN,
electric current is consumed even if communication is not carried out, so pay
attention.
EWhen RS-232C communication mode, none of the SW other than the power SW is
accepted.
EDoes not carry out printer output.
EActs as command input ¨measurement ¨data output.
EThe output timing is the same as the serial data output.
EThe communication request in the timing affecting the time control (during
measurement) is not accepted.
EWhen the next character or delimiter dose not come even after 5 seconds or
more at the time of receiving a command, send back error (ER00) and drops out
of the treatment.
EWhen about to start the data output but the personal computer is not ready to
receive the data, it become time out after 5 seconds.
EWhen RS-232C communication mode, C is displayed in the right bottom of the
external LCD.

Delimiter code
EWhen the above-mentioned command (+ data) + delimiter is inputted from the
control side, this product acts corresponding to the command and consecu-
tively outputs the error check code (+ data) + delimiter.
EThe delimiter is CR + LF and the break point of the data is a comma.
EThe input and output is carried out with a format of fixed length determined
for each command.
Error check code
EThere are kinds of error check codes as shown below.
OK00 : Normal operation
OK : Chromaticity measuring range over (same as  E0 display)
OK 2 : Luminance display range over (same as E9 display)
OK 3 : Luminance display range under (same as flickering display)
ER00 : Command error
(A command other than above-mentioned command is inputted, out of the
parameter setting range)
ER0 : Setting error (same as E display)
ER : Memory value error (same as E display)
ER 0 : Luminance and chromaticity measuring range over (same as E0 display)
ER 2 : Luminance display range, chromaticity display range simultaneous
over (same as E9, E8 display)
ER 9 : Display range over (same as E9 display)
ER20 : EEPROM error (same as E2 display)
(the value of the protect area of EEPROM is broken, cannot access
EEPROM, etc.)
ER30 : Battery out
(The power voltage same as B0 display is lower than BC voltage.)
