Page 9: Communicating With The Chr 150
Doc ref. CHR2-001-P2 Rev :D Communicating with the CHR 150 There exist 5 alternative methods for communicating with the CHR 150 sensor: a) The CHR front panel displays real time measurements and the 4-keys keypad allows a direct and easy access to sensor configuration. -
Page 10: Getting Started (Tutorial 1)
This chapter is a tutorial intended for new users who wish to familiarise themselves with the main characteristics of the CHR 150 sensor. For simplification purposes, this tutorial only introduces one measuring mode (« Distance » mode) and one communication method (the control panel). We recommend that new users follow this tutorial even if they wish subsequently to use another measuring mode or a different method for communicating with the sensor. - Page 11 STIL - CHR 150 – Operating and maintenance manual Doc ref.

Page 13: Selecting The Optical Pen
The CHR-150 controller may hold up to 6 calibration tables corresponding to 6 different optical pens. Available optical pens and their characteristics may be consulted in STIL website : www.wtilsa.com. Optical pens are passive devices and the controller can not identify the optical pen which is physically connected to it, so the operator has to select the calibration table corresponding to the optical pen that is physically connected. -

Page 22: Using The "Trigger" Mode
The « Sync in » signal is used to synchronise the CHR 150 sensor with external events, such as the approach of an object travelling on a conveyor belt. This mode must be activated by a special command (cf. -
Page 23: Main Functions Of The Chr 150
The ‘Dark’ command records and saves of the dark signal in the EEPROM of the CHR 150 for all sampling rates in succession. If the level of the dark signal is too high for low rates, the CHR 150 returns the index of the lowest sampling rate which is usable (see ‘Set Sampling rate’ command). -

Page 27: Averaging
The CHR 150 provides two types of time-domain averaging : data averaging and spectral averaging. In the first type, the averaging is performed on the measured data (after processing), in the second type, it is performed on the spectrometer signal (before processing). -
Page 28: Synchronisation Signals
The « Start Trigger » function puts the sensor on standby for a Trigger signal at the “Sync in” input (pin 1) on the SUB-D connector (cf. « Presentation of the CHR 150 »). The sensor activates as soon as a rising front is detected at the “Sync in”... -

Doc ref. CHR2-001-P2 Rev :D Control and acquisition of the data via the serial link The CHR 150 incorporates an RS232 serial link for controlling the sensor using a specific control language, and for retrieving the measurement data. The RS232 sub D at the CHR-150 controller back panel should be connected to a free COM Port on the host computer (COM1 or COM2) or on the device used for communicating with the sensor, using a direct (non-crossed) serial link wire. -
