Printer Interface

The printer output is provided for connecting an external printer through either of the two RS232 

serial ports. Both are DB9 position female connectors. In order to communicate properly with 

a printer, a Null Modem cable must be used and should be connected while the instrument is 

turned off. Proper Baud rate selection of the RS232 serial port is also required, and should be 

set at 9600. 

In order to set the output text string for the printer, computer interface is required. The options 

that exist for the output are as follows, and can be arranged according to individual require-

ments.

a = Temperature

b = Index

c = Index-TC

d = Solids

e = Solids-TC

f = Current Mode

g = Channel

h = Time

i = Date

j = ID

k = Method

Once communications with a computer is successful, type “sf” and press the enter key on the 

computer key board. This will display any current, text output string. To edit the string type sf, 

then a space and enter the desired letter codes. Example: 

sf cagh

. With the example entry of 

cagh

 the instrument will print Index-TC, Temperature, Channel and Time.

Computer Interface

The Mark III includes two serial communications ports (Fig 11). Both are 

DB9 position female connectors that are located on the left side of the 

instrument. Data may be downloaded to a computer, and custom channel 

files can be uploaded to the refractometer or deleted through these ports. 

Regardless of which of the serial ports is chosen on the Mark III, communi-

cations with a computer is possible.

Any Windows® based computer can be used successfully when interfacing 

with the Mark III. Communication through software such as HyperTerminal 

or Tera Term is required. HyperTerminal is usually found on all Windows® 

based systems as a standard software option. Recommended communi-

cation settings of the serial port from the computer are: Baud rate 9600, 

8 Data Bits, No Parity, 1 Stop Bit and Xon/Xoff Flow Control. Please note, 

that the Baud rate of the instrument must match that of the computer.

To connect the instrument to a computer use a compatible serial cable. 

Connection must be made while the instrument is turned off. To set up an 

output text string reference Printer Output.
