| <OSW_M_X> | Set or query manual/automatic mode:
1. X = 1 (automatic), 0 (manual), ? (query) 2. Successful return: <OSW_M_X_OK> 3. Failed return: <CMD_ERR> |
Send: <OSW_M_1> (sets the device to automatic mode)
Successful return: <OSW_M_1_OK> |
| <OSW_R_XXXX> | Set or query the delay for returning to automatic mode from manual mode:
1. XXXX = delay time (unit: minutes; 0000 = no return) – Successful return: <OSW_R_XXXX_OK> – Failed return: <CMD_ERR> 2. Send <OSW_R_?> to query the delay |
Send: <OSW_R_0030> (sets the delay for returning to automatic mode from manual mode to 30 minutes) |
| <OSW_W_X> | Set or query operating wavelength:
1. X = 0 (1310nm), 1 (1550nm), ? (query) 2. Successful setting return: <OSW_W_X_OK> 3. Successful query return: <OSW_W_X> 4. Failed return: <CMD_ERR> |
1. Send <OSW_W_1> (sets operating wavelength to 1550nm)
