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
les 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.
