6.3. COMPUTERS
To check the DOS computer a VGA monitor can be connected to see if it is running and the
output to the screen will look something like this:
(1,235,234,334,123,234,132)
The information that is being sent is door position and six detector counts.
The RS-232 data to the NT machine can be examined by using Hyperterminal. The settings
should be:
COM1,9600,N,8,1
Use standard troubleshooting procedures on the NT machine.
6.4. SIGNAL INTERFACE ASSEMBLY AND DETECTORS
Channel boards (RCS-110) may be substituted with system power on, but the power must be
turned off before changing the discriminator cards (RCS-120). This will ensure that the
discriminator settings are updated.
NOTE:
If channel cards are replaced permanently, the channels affected must be recalibrated.
