Control instruction:

(1) The optical switch can only execute one instruction at a time. Usually, the next instruction can only be entered after the program returns the corresponding value.
(2) Command all letters to be capitalized.
(3) In actual operation, enter the angle bracket "<" as the starting character and the angle bracket ">" as the ending character.

instructions	describe	Example
<OSWXX_OUT_YY>	Set the optical switch channel (instruction for optical switches with less than 100 channels): XX： Indicate module address (00~99) YY： Indicate the optical switch channel (00~99)	Send<OSW01_SUT_01>to indicate that the module address is 01 and the optical switch is set to channel 1; Successfully returned<OSW01_SUT-OK>; If the set channel exceeds the total number of channels of the optical switch, it will return<OSW01_SUT_CR>
<OSWXX_OUT_YY>	Set the optical switch channel (instruction for optical switches greater than 100 channels): XX： Indicate module address (00~99) YY： Indicate the optical switch channel (000-999)	Send<OSW01_SUT_001>to indicate that the module address is 01 and the optical switch is set to channel 1; Successfully returned<OSW01_SUT-OK>; If the set channel exceeds the total channels of the optical switch, it will return<OSW-OUT_CR>
<OSWXX_OUT_?>	Query the current channel of the optical switch XX： Indicate module address (00~99)	Send<OSW01_SUT_?> The module address is 01 to query the optical switch channel; If<OSW01_SUT_01>is returned, it indicates that the optical switch is currently in channel 1;
<OSWXX_TYPE_?>	Query the information of the optical switch XX： Indicate module address (00~99)	Send<OSW01TYPE_?> The module address is 01 to query the information of the optical switch; If<OSW01_Type_1x16_1310-1550NM_SM9/125>is returned Indicates that the optical switch is 1x16 optical on; Working wavelength: 1310~1550nm; Fiber type: Single mode 9/125
<OSWXX_ADD_YY>	Set module address XX： Indicate module address (00~99) YY： Indicate module address (00~99)	<OSW01_ADD_02>indicates that the module with address 01 is set to address 02, and if the setting is successful,<OSW02-AADD_OK>is returned
<OSW_ADD_?>	Query the current address of the module	<OSW_ADD_?> Search address Return<OSW01_SOK>to indicate that the address is 01
