Communication Protocol
●“_” expression underline.
● Communication protocols are all capital letters.
● The communication protocol commands, "<" as the start,">" as a terminator.
| Usage | Instruction | Description |
|
Set optical switch channels |
Send: <OSW_OUT_XX> |
Set the "XX" value to select the fiber channel. When "XX" is 00, the switch will be reset. Set 01 to select channel 1. A successful setup will return 1. It returns 2 when "XX" is larger than total channel amount. |
|
Return1: <OSW_OUT_OK> Return2: <OSW_OUT_OVERFLOW> |
||
|
Query optical switch channels |
Send: <OSW_OUT_?> |
Send the query command and it will return an "XX" value to indicate the current channel. |
|
Return: <OSW_OUT_XX> |
||
| Query optical switch type |
Send: <OSW_TYPE_?> |
Send the query command and it will return following basic information of the switch. Model: OSW-1X8 Wavelength Range: 800~2500nm Control Interface: RS-232 Connector: SMA905 |
|
Return: <OSW_TYPE_OSW-1X8_800~2500_300UM_R_SMA> |
Note: COM settings , Baud rate: 9600, Data bits: 8 bit, Stop bit: 1 bit , parity bit: None, Command error return “<OSW_ERROR>” .
Operation
(1) The optical switch transmits the command to control the optical switch through RS232 serial communication. The optical switch receives the command successfully and returns the response.
(2)To program the switch directly over USB (RS232 control), we would throw in a DB9 to USB adaptor (connector), and then the switch can be connected to the USB port on your device.
(3) The optical switch is bidirectional in operation.
