8 FLASH DOWNLOADING

There are 2 types of downloading:

i) User Mode Downloading -- this mode of flash downloading is used when upgrading
the indicator software

ii) Boot Mode Downloading -- this mode of flash downloading is used when the CPU is
brand new or flash program is lost due to unforeseen
circumstances.

There are 2 methods of downloading:

i) MS DOS Version.

ii) Windows Version.

User can choose either of the 2 methods.

8.1 DOS Version

Do these steps before proceed :
a) Make a directory eg DI 80 on the PC. Copy the program FAST80.EXE onto the
created directory DI 80.

b) Copy the DI 80 main software DI80.MOT (hex file) on to the directory DI 80.

c) Connect DI 80 via SIO1 using RS232 cable to COM 1 or 2 of the PC.

8.1.1 USER MODE Downloading

1) Switch the option switch to USER mode on the DI 80.
(This switch is accessible by removing the printer module. See below)

Replace blank bracket or RS232/485 I/F Board (TWB -02350) next to connector board (TWB-02310)
with analog output I/F board (TWB -02370).

Set SPEC 58 is 1000 to enable Analog Output function, while set 0000 to disable it. Hardware jumper
setting selects current or voltage mode, refer to silk screen on PCB. Only one output mode is
available at the same time.

14.4 CALIBRATION PROCEDURE

Analog output value should be 4mA at Zero Point and 20mA at Capacity Weight. If the output
values are not the appropriate value, adjust those by the following procedure.

ZERO – Rezeroing
SPAN1 – Fine adjustment
SPAN2 – Coarse adjustment

Before startup, precautions have to be taken to ensure all potentiometers are not overturned. After
the check has been done, proceed with setup.

The procedure can be accomplished as follows:

STEP 1 – Zero offset adjust

Load all zeros, then tune the “ZERO”.
For the voltage mode, adjust to 1V, while for the current mode, on the other hand, adjust to 4mA.

STEP 2 – Coarse adjustment

Load all ones, adjust the “SPAN2” which constit utes the varying of the operating range. Careful
tuning has to be taken, as it is very sensitive. It is termed as coarse adjustment because it varies a
wider range. For the voltage mode, adjust to approximately 8.99V for the 0-10V range and
approximately 4.2V for the 0-5V range. For the current mode, adjust to approximately 19.99mA.

STEP 3 – Fine adjustment

Adjust “SPAN1” which constitutes in fine adjustment to the actual full span. This has to be done
after adjusting “SPAN2”.

This adjustment algorithm is iterative, therefore, STEP1 to STEP3 has to be repeated until
convergence is obtained.

DI-80 Limited Warranty

Rice Lake Weighing Systems (RLWS) warrants that all RLWS equipment and systems properly installed by a
Distributor or Original Equipment Manufacturer (OEM) will operate per written specifications as confirmed
by the Distributor/OEM and accepted by RLWS. All systems and components are warranted against defects
in materials and workmanship for two (2) years.

RLWS warrants that the equipment sold hereunder will conform to the current written specifications
authorized by RLWS. RLWS warrants the equipment against faulty workmanship and defective materials. If
any equipment fails to conform to these warranties, RLWS will, at its option, repair or replace such goods
returned within the warranty period subject to the following conditions:

• Upon discovery by Buyer of such nonconformity, RLWS will be given prompt written notice with a detailed explanation

of the alleged deficiencies.

• Individual electronic components returned to RLWS for warranty purposes must be packaged to prevent electrostatic

discharge (ESD) damage in shipment. Packaging requirements are listed in a publication, “Protecting Your Components
From Static Damage in Shipment,” available from RLWS Equipment Return Department.

• Examination of such equipment by RLWS confirms that the nonconformity actually exists, and was not caused by

accident, misuse, neglect, alteration, improper installation, improper repair or improper testing; RLWS shall be the sole
judge of all alleged non-conformities.

• Such equipment has not been modified, altered, or changed by any person other than RLWS or its duly authorized repair

agents.

• RLWS will have a reasonable time to repair or replace the defective equipment. Buyer is responsible for shipping charges

both ways.

• In no event will RLWS be responsible for travel time or on-location repairs, including assembly or disassembly of

equipment, nor will RLWS be liable for the cost of any repairs made by others.

THESE WARRANTIES EXCLUDE ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED,
INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY OR FITNESS
FOR A PARTICULAR PURPOSE. NEITHER RLWS NOR DISTRIBUTOR WILL, IN ANY EVENT,
BE LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES.

RLWS AND BUYER AGREE THAT RLWS’S SOLE AND EXCLUSIVE LIABILITY HEREUNDER
IS LIMITED TO REPAIR OR REPLACEMENT OF SUCH GOODS. IN ACCEPTING THIS
WARRANTY, THE BUYER WAIVES ANY AND ALL OTHER CLAIMS TO WARRANTY.

SHOULD THE SELLER BE OTHER THAN RLWS, THE BUYER AGREES TO LOOK ONLY TO
THE SELLER FOR WARRANTY CLAIMS.

No terms, conditions, understanding, or agreements purporting to modify the terms of this warranty shall have any legal effect unless
made in writing and signed by a corporate officer of RLWS and the Buyer.
