The measuring device is fitted with a serial interface (11) for exchanging data with a computer. This can be
found on the right hand side under a cover. Open the cover with a pointed object. The interface is in the form
of a 3.5mm jack plug socket and requires a compatible data cable, which is an optional extra.

You can order the matching interface cable using the following order numbers:

Order no.: 122156 RS232 interface cable with jack plug and 9-pole D-USB plug
Order no.: 122703 USB interface cable with jack plug and USB plug

The data cable has the following components:

Center contact 

Pin 4

External contact 

Pin 2
A 2.2 KOhm is required between pin 2 and pin 5.

The serial data signal is made up of 16 Bits in the following order:

D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0

Each data bit has the following function:

D0

End signal

D1 to D8 Measuring value
D1 = 

smallest digit (LSD), D8 = largest digit (MSD).
If 1234 is displayed, the bit rate is: „00001234“

D9

Decimal point (DP) at the corresponding spot from right to left; 
0= no DP; 1=1DP; 2=2DP; 3=3DP

D10

Polarity; 0 = positive, 1 = negative

D11+D12 Measuring value on the display; R = 70 / G = 71 / B = 72 / H = 42 /  S = 73 / L = 99 
D13

Data bit when sending the colour value: Red = 1 / Green = 2 / Blue = 3 / Hue = 4 / Sat = 5 / Lum = 6

D14

4

D15

Start bit = 02

The RS232 data format is: 9600, N, 8, 1

The colour analysis device RGB-2000 is maintenance-free apart from replacing the batteries and cleaning it
once in a while. Use a clean, lint-free, antistatic and dry cloth to clean the device. Do not use any abrasive or
chemical agents or detergents containing solvents.

If the battery symbol 

appears on the display, the battery has to be replaced as soon as possible to pre-

vent wrong measuring results.
