SBIG ST-402 Operating Manual

Extremely

 

Important!

 

In the past SBIG has shipped products like the STV, ST-5C and 
ST-237/A that used a 12-Volt, Center-Negative power supply.  
Starting with the ST-402 we are switching to Center-Positive 
12-Volt power supplies.  How do you know the difference? 

All 12-Volt, Center-Positive power jacks and receptacles are 
locking with a threaded collar

.  

Don’t ever try to mate an 

unthreaded power supply to a threaded camera or vice-versa

USB Cable –

 Included is a 15-foot, USB 2 certified, A-to-B type, USB 

cable.  USB has a limit of 15-foot cables but the range can be 
extended with active boosters.  Relatively low-cost (~$30) 15-foot 
boosters that can be stringed together are available from such 
sources such as  <www.usbgear.com>.  Long haul boosters (more 
expensive) are available from <www.icron.com>.  Also note that 
putting a hub at 15 feet will allow you to go another 15 feet. 

Tracking Cable –

 This cable looks like a simple “RJ-11 telephone cable” 

but in fact is a “6-pin reversed RJ-11 telephone cable”.  Telescopes 
require 6-pin autoguider cables and reversed means that unlike 
ordinary phone cables, this one is flips the order of the wires.  You 
can tell a tracking cable from an ordinary cable by noting that with 
tracking cables the tines that lock the RJ-11 jack into the receptacle 
are both on the same flat side of the cable or when the ends are put 
side by side the colored wires inside are in opposite order on the 
two connectors. 

Software –

 We include several CD-ROMs with the ST-402 but the most 

important one is labeled “

SBIG Software and Catalog

”.  This 

disc contains the 

drivers

 and 

CCDOps

 software you’ll need to use 

the camera. 

Very Important

Before you attach the ST-402 to your computer for the first 
time you MUST install the software as described below.

Installing the Software 

Installing USB drivers on a 

Windows

 system can be a difficult task if you 

don’t follow the instructions to the letter.  Please don’t plug the camera into 
the computer until instructed to do so below and please follow the 
instructions carefully. 

1.

 

Disable Driver Signing

 – 

Windows XP

 adds an extra level of security 

to installing drivers that will complicate our installation.  To disable it 
open the 

System

 Control Panel in the 

Start Menu

 and then select the 

Hardware

 tab.  Click the 

Driver Signing

 button and in the dialog that 

appears select 

Ignore

 then click 

OK

.  Click 

OK

 one more time to close 

the Control Panel. 

 

2.

 

Insert the 

SBIG Catalog and Software

 CD-ROM in your computer 

and on most systems the installer program will automatically start.  If it 
doesn’t, explore the CD-ROM drive and double-click on the 

autorun.exe

 icon.  Then click on the 

Setup a New Camera

 button. 

3.

 

Install CCDOps

 – Click on the 

Install

 

CCDOps

 button to install it on 

your computer, and then follow the on-screen instructions.  

CCDOps

 is 

our powerful yet simple-to-use image acquisition and image processing 
software and we’ll use it extensively throughout this manual. 

4.

 

Install the Driver Checker

 – Click on the 

Install

 

Driver Checker

 

button to install it on your computer and then follow the on-screen 
instructions.  The 

Driver Checker

 is a utility program that installs and 

maintains the drivers that are required for operating the ST-402 under 
the Windows Operating System. 
     At the end of the install when you are given the 

option

 to 

launch

 the 

Driver Checker

.  Check that option. 

5.

 

When the 

Driver Checker

 starts it will ask you if you have an 

Internet 

Connection

 on this machine.  If you do then answer 

Yes

 otherwise 

answer 

No

. The Driver Checker will install the camera drivers and at 

this point all your drivers should all be current:
