Interconnections
All Input, Output and power connections to the 204 are made at the rear panel of the indicator.
Connections for the Load Cell input and the RS-232 Serial I/0 are all made via 9 pin "D"
shaped subminiature connectors. The 12VDC 300 mA wall plug-in UL/CSA listed power
supply is connected using a power jack. Figure No. 2 illustrates the layout of the rear
connector panel.
Power Supply
To apply power to the 204 using the power supply, connect the power cable's connector into
the power jack on the back of the indicator and then connect the 12 VDC, 300 mA power
adapter into the proper electrical outlet. The 204 is now ready for operation.
Batteries
The 204 can use 6 "C" size Alkaline, Ni-Cad
or NiMH batteries (
not included
). If you wish
to operate the 204 from batteries, you must
first obtain and install batteries before
operations can begin. The batteries are
contained in a battery holder inside the
indicator. Access is via a removable panel
on the back of the indicator.
The 204 can operate for 200 hours of
continuous use when using Alkaline batteries
or with fully charged Ni-Cad or NiMH
batteries, 50 hours of continuous use.
NOTE: When using Alkaline batteries, make
sure the
