Pin Definitions
DB9 (TTL level):
| Pin number | Signal direction and type (In/Out/Power) | Pin Definitions | Function Description |
| 1 | In | D0 | Data bits. D3~D0 are binary numbers, with D3 being the high-order bit and D0 the low-order bit. These 4 data bits can control up to 16 optical switches. Where 0000b = channel 1; 1111b = channel 16. Data is sent according to the actual number of channels of the optical switch during use. |
| 2 | In | D1 | |
| 3 | In | D2 | |
| 4 | In | D3 | |
| 5 | In | /Reset | A low level resets the channel to channel 0, while a high level indicates that the data bits are valid. |
| 6 | Out | /Ready | Low level indicates readiness for reset or data reception. |
| 7 | Out | Error | A high level indicates a problem with the optical module. |
| 8 | Power | GND | ground wire |
| 9 | Power | DC 5V | DC 5V, 1.0A operating power supply |
DB15 (TTL level):
| Pin number | Signal direction and type (In/Out/Power) | Pin Definitions | Function Description |
| 2 | In | D0 | Data bits D5~D0 are binary numbers, with D5 being the high-order bit and D0 the low-order bit. A 6-bit binary number can control up to 64 optical switches. Specifically, 000000b = channel 1; 111111b = channel 64. When using this method, the data sent should be based on the actual number of optical paths of the optical switch. |

| 11 | In | /Reset | Low level resets the system; high level indicates that the data bits are active. |
| 7 | Out | /Ready | Low level indicates readiness for reset or data reception. |
| 8 | Out | Error | A high level indicates that an error has occurred. |
