# J-Chip
J-Chip is a Japanese manufacturer of RFID active timing systems\
Official website :
The connection with the J-Chip hardware is established in TCP-IP. The IP address and port to use to communicate with the box are those entered in the Control Panel utility, in the Network tab. The Control Panel is provided by J-Chip.
{% hint style="info" %}
In early 2019, J-Chip released a firmware update that allows both the time and date to be sent for a transponder read. This was not the case in previous versions. We strongly recommend using the latest firmware (version 2.02.0 and later) and enabling 'Date mode' from the Control Panel. Otherwise, on events taking place over several days, the correct consideration of the read date may prove problematic.\

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.wiclax.com/en/use-wiclax/acquisition-of-timing-data/the-different-systems/j-chip.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
