Set up SCTs for download accep

tance: For all SCT860s to be up

graded, press the UP, LEFT, and

ENTER buttons simultaneously for 2

seconds until the displays read:

LOADING PROGRAM. This can apply

to all SCTs connected for remote

control, if desired, however – DO NOT

DOWNLOAD THE FIXED CLOCK

FIRMWARE TO SCTs THAT DO NOT

HAVE THE 1002366 BOARD

INSTALLED. In many installations,

only one SCT will need to be loaded

with the fixed clock firmware.

On the PC, run the SCT860 Control

Program. On the opening screen,

select from the top menu line the

Tools selection. Then select Down

load Firmware... In the new window

that opens there is a selection box

listing all of the files available for

download. For use with the 1002366

board, select Fixed Version 1.4 or

higher hex from the list. Select the

comm Port that you are using on your

PC and then select Start to begin the

download.

When finished, the units will reset

themselves. Press the UP arrow

button on each unit to confirm that

VERSION 1.4F or higher is now

installed.

If it is ever desired to remove the

1002366 board and replace the

original factory installed jumpers, you

must download the Auto Version

firmware to the SCT.

If additional SCTs, not being up

graded with the 1002366 board,

currently have firmware below Version

1.4, you may wish to download the

latest version. In this case you will

need to perform a second download

operation, selecting only these SCTs,

and download the Auto Version 1.4

or higher hex file to those units.

Updates from previous versions

include: revised/limited acquisition

range, correction of a DVB 256QAM

interleave setting, and a few other

minor adjustments (depending on

your current version).

OPERATION

Follow the instructions in the SCT860

instruction manual. Now that the 1002366

board is installed, the FIXED clock option

may be selected and the output BD RATE

(baud rate which is the symbol rate) may

be set. The original AUTO clock mode is

still selectable, if it is desired.
