SAM 935™ Instruction Manual

7

Most printers compatible with the Epson command set (9-pin,
24-pin, and ink jet printers) are supported. If your printer does not
have an option for a serial port connection, you may need to pur-
chase an RS-232 serial to Centronics parallel adapter (available as
an option from BNC). Otherwise, the printer may be attached to the
SAM 935 in exactly the same fashion as you would attach it to the
serial port of any computer.

Set the printer serial configuration to 19,200 baud (or another baud
rate if you have changed the SAM 935 defaults), 8 data bits, 1 start
bit, 1 stop bit, no parity. It is also important, if your printer has this
feature, to set the font to the Latin1/European font rather than the
italic font so that special characters will be printed correctly. See
your printer manual for details.

After starting up the SAM 935, set the serial speed to match the printer’s in the SAM 935 Utilities menu;
see Section 6.11.

Connecting to a Remote Computer

The SAM 935 may be connected to a remote computer running the PGT QUANTUM MCA

®

software. The

Quantum software comes with AutoLoad, a program for uploading spectra saved in SAM 935 to a personal
computer. The installation and use of this program is covered in Appendix A: AutoLoad.

To make the hardware connection between the SAM 935 and the personal computer, a null modem cable
is required. The SAM 935 may be connected to any serial port of the host computer, provided that this

serial port is accessible from Microsoft Windows

®

.

1.

Simply align the connector on one end of the cable with the 9-pin serial connector on the SAM 935
(RS-232), and press to insert.

2.

Repeat with the connector on the host computer.

3.

After starting up the SAM 935, set the serial speed to match the printer’s in the SAM 935 Utilities
menu; see Section 6.11.

4.

In the hardware search program, select the baud rate and COM port to which the SAM 935 is
attached.

5.

On the SAM 935, press the U

TIL

key. Select R

EMOTE

(F4).

6.

Press the U

PDATE

button. The Quantum hardware search software should automatically detect the

SAM 935 when you press the U

PDATE

button in its MCA Devices Auto Configuration window.

Connecting an Optional External Detector

If you purchased an optional external detector with the SAM 935, attach the supplied LEMO connector to
the port on the right-hand side of the SAM 935 (holding the unit in normal operating mode). The other end
of the LEMO connector attaches to the external detector.
