for a period of one (1) year from the time of shipment from Techno facilities. Techno's sole obligation under this warranty is
limited to repairing the product or, at its option, replacing the product without additional charge, provided the item is properly
returned to Techno for repair as described below. The provisions of this warranty shall not apply to any product that has
been subjected to tampering, abuse, improper setup or operating conditions, misuse, lack of proper maintenance, or
unauthorized user adjustment. Techno makes no warranty that its products are fit for any use or purpose to which they may
be put by the customer, whether or not such use or purpose has been disclosed to Techno in specifications or drawings
previously or subsequently provided, and whether or not Techno's products are specifically designed and/or manufactured
for such a purpose.

THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES EXPRESSED OR IMPLIED. ALL OTHER WARRANTIES,
INCLUDING, BUT NOT LIMITED TO, ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR
PURPOSE, WHETHER EXPRESSED, IMPLIED, OR ARISING BY OPERATION OF LAW, TRADE USAGE, OR COURSE
OF DEALING, ARE HEREBY DISCLAIMED. THERE ARE NO WARRANTIES THAT EXTEND BEYOND THE
DESCRIPTION ON THE FACE HEREOF.

LIMITATION OF REMEDY

In no event shall Techno be liable for any incidental, consequential, or special damages of any kind or nature whatsoever.
Techno is in no way liable for any lost profits arising from or connected to this agreement or items sold under this
agreement, whether alleged to arise from breach of contract, expressed or implied warranty, or in tort, including, without
limitation, negligence, failure to warn, or strict liability.

RETURN PROCEDURE

Before returning any equipment in or out of warranty, the customer must first obtain a return authorization number and
packing instructions from Techno. No claim will be allowed nor credit given for products returned without such authorization.

after power turns on. The X and Y axes should move back and forth slightly. The
Z axis may or may not move, depending on which version of the internal EPROM
program is used.

4. If the DaVinci and the PC are communicating properly, the DaVinci will display a
self-test message on the computer screen. The self-test message consists of a
character stream, which continues until the space bar is pressed. After the
space bar is pressed, any characters typed on the computer will appear on the
computer screen and will be sent as a message to the DaVinci. When the
message is received by the DaVinci, it will send the same character back to the
computer. That character will appear on the computer screen twice - once after
being typed in, and once after being sent back from the DaVinci.

5. If the test is successful, press the Reset button on the DaVinci, and proceed to
the program you are going to use to make your part.

Wiring For 9 To 9 Pin RS232 Serial Cable

Diagram 5: Wiring Set-Up Between DaVinci And PC

The DaVinci uses a three-wire serial communication system (transmit, receive, ground).
Jumpers between pins 4 and 5, and between 6 and 20, can be used to disable hardware
handshaking. The Techno controller card is configured as a DTE system and the
computer (PC) host is assumed to be a DCE system (i.e., pin 2 sends information and pin
3 receives information). The serial controller makes use of standard circuits and will
operate with most PC's. The PC should be configured as a DCE device.

The communication parameters require the following settings:

9600 Baud
8 Bits
1 Stop bit
No Parity

16

Switch Settings

Switch settings for the baud rate and the acceleration rate may be changed, if necessary.
There are two switches for the baud rate, and two for the acceleration rate. All four
switches are found on the same DIP switch, which is located on the left leg of the DaVinci,
behind the panel. (See diagram 6 below.)

DIP switch

(contains baud rate and
acceleration rate switches)

Left leg

(panel removed)

Diagram 6: DIP Switch For Baud And Acceleration Rates

The DIP switch contains eight switches: 1 and 2 set the baud rate, 3 and 4 set
acceleration, and switches 5 through 8 are non-functional.

Adjusting The Baud Rate

The position of switches 1 and 2 determine the communication speed, or baud rate. For the
default setting of 9600 baud, switch 1 is OFF, and switch 2 is ON. A setting of 4800 baud
requires switch 1 to be ON, and switch 2 to be OFF. (Refer to Diagram 7 below.)

Adjusting The Acceleration Rate

The position of switches 3 and 4 determine the acceleration rate for all motors. For the
default setting of 75 Hz/ms, switch 3 is ON and switch 4 is OFF. Other acceleration rate
settings require different combinations of switch positions. (Refer to Diagram 8 below.)
