Page 5: Introduction
This manual applies to indicators using version 8.00 or higher of the STC-2200 firmware. Configuration and calibration of the indicator can be accomplished by pressing the indicator front panel keys, the serial command set or Rice Lake Tools configuration utility. Each indicator is designed to work with one scale and has the capability to be daisy chained to one protocol interface to communicate with a network interface controller for larger jobs. -

Page 28: Filter Parameters
SCT-2200 Weight Transmitter 4.4.1 Filter Parameters Standard digital filtering uses mathematical averaging to compensate for the noise that the A/D converter sends periodically because of external vibration. This filter compensation makes data less susceptible to a DC signal bias error for some signals. Each of the filters of the SCT-2200 are intended to compensate for different types and intensities of digital noise and vibration. -

SCT-2200 Weight Transmitter Zero Dead Load A/D Counts Table 5-2 lists the ideal A/D counts that result from input signals of 0Ð45 mV with zero deadload. Actual values will typically be higher than the values shown in Table 5-2 but the ideal values can be used when calibrating the indicator with no attached scale. -
Page 39: Communications
The COM2 serial port is bi-directional (full duplex) and uses an RS-232 for transmitting data. It is mainly used to connect printers, PCs, and PLCs. The transmission speed may be selected in the setup as: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 baud. © Rice Lake Weighing Systems ● All Rights Reserved... -
