Optional Equipment
Model 264 Printer
The LMI Model 264 accessory printer is offered as an option for the
Model 2929 Scaler.
A recycle switch on the Model 264 is provided for continuous cycling, if
desired. \When the counting time has reached the preset selection, the
count is printed, and the scaler and timer are reset to 0 to begin again.
The preset time is variable from 6 seconds up to 990 minutes.
The calculator may be used for any normal calculation function as long
as the keys are not activated at the same time the scaler is feeding its
information to the printer.
NOTE: When operating two Model 264 printers and a recycle is required,
be sure that only one printer has its recycle switch ON.
Model 464 RS-232 Interface
The LMI Model 464 RS-232 interface connects to the Model 2929,
allowing communication between the scaler and a device with an RS-
232c I/O (Input/Output), such as a personal computer (PC).
A command input through the RS-232 port to the interface is interpreted
and action is taken accordingly. The scaler can be started, stopped and have
data extracted by way of commands sent to the interface. The timed count
may be controlled by the scaler front panel, interface internal timer or by a
timer in the controlling device. The interface internal timer is programmable
to 4.5 days.
Other commands allow the user to read the interface timer, read the
current count, start a timed count using the interface internal timer, and
ask the interface if the timer has timed out.
