The RS485 cross cable is a 1x3, 2x4 cable such as C04500, used for

COMM ports are set up.

3. Power up the SDI box.

4. Set SWA-7 DOWN and SWA-8 DOWN. Set all other switches UP.

5. Set SWA-8 UP.

6. Give the command:

BOOTSDI SDI.S19 1

BOOTSDI SDI.S19 2

depending on whether the SDI is connected to COM1 or COM2.

7. The SDI LED should blink rapidly and somewhat irregularly, for duration

of the download.

8. BOOTSDI should print a line of dots, and then say:

sdi.s19 successful

Done.

If so, go to step 9.

9. If BOOTSDI, after several seconds, says:

no sync from SDI, enter=retry, q=quit >

You may close SWA-8 again momentarily, then open it, press ENTER, and

return to step 6.

10. When you have received the “Done” message, set SWA-8 CLOSED.

11. Immediately set SWA-7 OPEN.

be signaled by regular on-off blink of the LED, a little faster than 30

blinks/minute.
