8 UNITEC Interface SCIII
Gasboy CFN Series
The RS485 cross cable is a 1x3, 2x4 cable such as C04500, used for
connecting the Current Loop Interface to the Site Controller. The RS422

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
or
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.
12. Immediately set SWA-8 OPEN and the SDI will go to run mode. This should
be signaled by regular on-off blink of the LED, a little faster than 30
blinks/minute.

3. Set SWA-7 DOWN and SWA-8 DOWN. Set all other switches UP.
4. Set SWA-8 UP.
5. After these steps have been completed, give the command ‘L’ which causes
