Instructions For Optical Fiber Delay Line
Direction for use:
You are welcome to use our fiber delay line products, please read the product instructions before use.
Software interface of Optical Fiber Delay Line:
Note:
1. Download the controller and init command on the official website and under the same interface on the computer. Connect the delay line and power it on as required (see connection installation drawing)
2. Select the corresponding specifications according to the specifications you purchased， and be sure to choose the correct range (100,330,660,1200,1500PS delay line). Select the corresponding link serial port, select the default value of 9600in the port rate selection column, and press OK; then the delay line returns to zero! Also, determine that a PorterRateSettings key appears to the left of the key! If you want the delay line to run at other baud rates! Select the port rate you need after the delay line at 9600 initializes out of the Baud Rate Settings key! (Note: The initial wave rate of the delay line is 9600! You can reset the port rate you want only after initializing outside the Baud Rate Settings key at 96o0! (The interface is initialized state and the delay line automatically zero)
3. The mode you want to test, there are two choices:
- General mode– — – -directly input the amount you want to delay to determine! The current position of the controller displays the current delay data in real time;
- Tour mode—-——Tour from point to point! Enter one point and another point and fill in the stay time(generally 200 ` 1000ms); start! The current location of the controller displays the current delay data in real time!
4. The determination key selected by the serial port is also the initialization zero key of the boot light delay line (Note: zero position in general mode, press the determination key in general mode to return to zero; when the delay line needs to return to zero during normal debugging, please do not zero in initialization state mode, otherwise it is easy to cause lag).
5. In case of sudden power failure during the use of the product (or other accidents cause it to stop in the middle of the operation), the product should be initialized first after reopening (press the determination key after the serial port
selection)!
6. Download the controller using the company’s products will naturally generate a TXT text record delay line for real-time running track!
7. Link port can be customized as RS232 and RS485 according to customer requirements
Matters Need Attention:
1. Link the R232 master terminal with R232 nine-pin USB and 1ink R 232 as required, link the other end with the delay line with two red and black powerlines (red is DC+/ 12V; black is DC-); access the corresponding required power supply according to the regulations, otherwise the delay line will be damaged!
2. The init-command text is recommended not to be modified， otherwise, the delay line will not work properly!
3. In case of problems, please contact the company in time. It is strictly prohibited to disassemble, otherwise maintenance and after-sales service!
