3.2.3 Temperature Meter
The temperature meter shows when heat block has reached the selected temperature setting
and has stabilized within

2 degrees of set point. From a cold start, this could take 5 to 8
minutes. The heat block is stabilized when the needle is centered.
3.2.4 Function Connectors
The function connectors provide the I/O lines to the heat source including AC power in and
gating signals out.
The six-contact circular connector (on the left side) is compatible with the power cord included
with the system. One end of the supplied 2100-832 power cord is connected to the heat
source. The other end is plugged into a stable grounded three-wire AC outlet capable of at
least 105 VAC at 15 amperes.
The table below shows the pin assignment for the six-contact connector.
Pin Assignment
A AC Neutral
B AC Hot
C AC Ground
D TO1 (positive output pulse)
E TO2 (positive output pulse)
F Ground
The eight-contact circular connector (on the right side) isn't used when calibrating STC
scanners.
For safety's sake, always cover this connector with the supplied dust cap.
3.2.5 Fuse
On the front of the heat source is a 2-amp 250-volt fast-acting fuse. It protects the heat source
from excessive current.
