2.2 Communication Interface connection Description

(1) RS-232 interface
When connecting a device to a computer, use a DB9 serial port crossover cable with holes on both ends. That is, pin #2 and pin #3 at both ends are crossed, pin #5 at both ends is connected, and the rest of the pins are not connected.
(2) RJ45 Ethernet interface
When connecting a device to a computer through a switch, use a straight-through cable (the wiring sequence at both ends is 1-orange and white, 2-orange, 3-green and white, 4-blue, 5-blue and white, 6-green, 7-brown and white, 8-brown). When the device is directly connected to the computer, cross wires should be used (one end is: 1-orange-white, 2-orange, 3-green-white, 4-blue, 5-blue-white, 6-green, 7-brown-white, 8-brown; The other end is: 1- green white, 2- green, 3- orange white, 4- blue, 5- blue white, 6- orange, 7- brown white, 8- brown).

3. Panel operation instructions

(1) Keyboard lock: The communication interface of the channel device sends corresponding commands to set whether the keys on the panel are allowed to use. See "Communication Protocol Description" for details. When the panel key is locked, the corresponding parameters cannot be set through the panel.
(2) Setting whether the initial interface allows channel switching.

■ The procedure for allowing channel switch on the initial interface: ① press Enter to Enter the menu when you press the button to allow it to be used. ② Press "▲" or "▼" key to select "1. Channel lock setting"; ③ Press "Enter" to Enter. ④ Press "▲" or "▼" key to select "allow switch"; ⑤ Press "Enter" to confirm the completion. ⑥ During the whole process, press Esc to return to the previous step.

■ The procedure for locking a channel switch on an initial interface: (1) press Enter to Enter the menu when you allow it to be used. ② Press "▲" or "▼" key to select "1. Channel lock setting"; ③ Press "Enter" to Enter. ④ Press "▲" or "▼" key to select "lock switch"; ⑤ Press "Enter" to confirm the completion. ⑥ During the whole process, press Esc to return to the previous step.

(3) Channel switching

(5) Set the time of automatic scanning and start automatic scanning

■ Press the ① key to Enter the menu. ② Press "▲" or "▼" key to select "4. Automatic scan Settings"; ③ Press "Enter" to Enter. ④ Press the key "▲" or "▼" to select the "hour" of the scan interval; ⑤ Press the "Enter" key to confirm; ⑥ Press "▲" or "▼" key to select "minutes"; ⑦ press the "Enter" key to determine; ⑧ Press "▲" or "▼" key to select "second"; ⑨ Press Enter. If the time is not zero, automatic scan is started. ⑩ During the whole process, press Esc to return to the previous step.

■ During automatic scanning, there are three ways to stop scanning on the panel: (1) when the initial interface allows channel switching, press "▲" or "▼" to switch channels to stop scanning; ② Switch channels under "2. Channel mandatory Selection" to stop scanning. ③ In the menu "4. Automatic scan Settings" set the scanning time interval to "00 hours, 00 minutes, 00 seconds" to stop scanning.

(6) Device address setting, which can be used to control multiple devices with different addresses in the case of tight serial port resources.

■ Press the ① key to Enter the menu. ② Press "▲" or "▼" key to select "5. Address setting"; ③ Press "Enter" to Enter. ④ Press "▲" or "▼" key to select "new address"; ⑤ Press "Enter" to confirm the completion. ⑥ During the whole process, press Esc to return to the previous step.

(7) The setting of serial port baud rate can meet the Settings of different baud rates. The baud rate can be set as follows: 1200, 2400, 4800, 9600, 19200, 57600, 115200, usually set as 19200. (Note: The baud rate Settings take effect only after a restart.)

■ Press the①key to Enter the menu. ② Press "▲" or "▼" key to select "6. Baud rate setting"; ③ Press "Enter" to Enter. ④ Press "▲" or "▼" key to select "baud rate"; ⑤ Press "Enter" to confirm the completion. ⑥ During the whole process, press Esc to return to the previous step.

(8) LCD backlight delay setting

■ Press the ①key to Enter the menu. ② Press "▲" or "▼" to select "7. LCD backlight"; ③ Press "Enter" to Enter. ④ Press the key "▲" or "▼" to select the delay time; ⑤ Press the "Enter" key to confirm; ⑥ During the whole process, press Esc to return to the previous step.

(9) Error message prompt

■ Error 1 -- indicates a data overflow.
■ Error 2 - indicates that the optical switch module is operating incorrectly.

.4. Description of upper computer monitoring

The device can receive control signals from the computer through the RS-232 (or RS-485) interface on the front panel to realize automatic measurement or real-time monitoring (using the serial port monitoring system or serial port software), or remote monitoring through the Ethernet port.

4.1. Program control instruction
(1) This instrument can only execute one instruction at a time. Usually wait until the program returns the corresponding value before entering the next instruction.
(2) Please use capital letters.
(3) Input the sharp bracket "& LT;" in the actual operation. As an opening character, a parentheses ">" As a terminator.
