We are using the Cerberus CS1140, an earlier fire control host. There are not many related technical documents or questions that can be found on the Siemens forum.

We want to write data to the C-BUS gateway “E3H020”. According to the manual, we first set the programming switches of S5-1 and S5-2 to "on", and S3-1 to S3-5 to "off". Then, after plugging the gateway into the fire control host, we use the connector "ST2" to link it to the external modem B3D021. Finally, connect it to the computer and try to write data through the Algoworks ep7f software.

When executing the command to connect to the workstation, the connection failed and the software prompted "Command not executable, error code 2C02". At this point, check the log Prompt "Station neither in fastload nor in download mode nor DB connectable." and "check cables, check firmware (< EP7F)."

We also tested the connection of other function cards using the external modem B3D021, and initially confirmed that both the Algoworks ep7f software and the external modem B3D021 can be used normally.

I hope someone can help solve this connection failure issue, help determine whether the gateway "E3H020" is damaged, or check if there are any errors in our data writing operation steps. Thank you.

我们使用的是Cerberus CS1140,比较早期的消防主机，在西门子的论坛上已经搜索不到太多相关技术文档或问题。

我们想给其中的C-BUS网关卡"E3H020"写入数据，按照说明书，我们先将S5-1和S5-2编程开关设置为“on”，S3-1至S3-5均为“off”，接着将网关卡插入消防主机后，再使用接头"ST2"链接至外部解调器B3D021，最后连到电脑，尝试通过Algoworks ep7f软件写入数据。

执行连接工作站命令时，连接失败，软件提示“命令不可执行，错误代码2C02”，此时查看日志，提示“Station neither in fastload nor in download mode nor DB connectable.”和“check cables, check firmware (＜ EP7F)”。

我们也测试了使用外部解调器B3D021连接其他功能卡，能初步确认Algoworks ep7f软件、外部解调器B3D021都是可以正常使用的。

希望有人能帮忙解决这个连接失败的问题，帮助判断网关卡"E3H020"是否损坏，或是检查我们写入数据的操作步骤是否出错，谢谢。

你连接的线是错误的，当然连接不了E3H020

The cable you connected is incorrect, of course it cannot connect to E3H020.

你好;

世界各国都在西门子论坛上寻求帮助。 为了方便我们的交流，我们选择英语作为论坛的通用语言。 请在您下次访问时用英语给我们写信，或者像我现在一样使用电子翻译器。

Hello;

Help is requested on the Siemens forum from countries all over the world. To make our exchanges easier, we have chosen English as a common language on the forum. Please write to us in English on your next visit, or use an electronic translator, as I am doing now.

If you can, it would be most helpful to the original poster if you could indicate which cable would allow him to connect to a E3H020 module.

Hope this helps,

Daniel Chartier

不好意思，我还不太熟悉这个论坛的使用方式，我重新发送一下回复。

Sorry, I'm not familiar with how to use this forum, so I'll re-send the reply.

谢谢您的回复，我给您提供一张图片，您说线是错误的，意思是我们得用这种一分二的连接线才能连接？按照说明书的第二种连接模式？

那我们是否要准备K1D140这个模块？两路同时连接消防主机？

如果是单纯线缆的问题，我们有尝试通过淘宝商家定制这种14pin线缆，有没有什么必要的技术参数？我们现在是按14pin接口，2.5mm线间距的标准来定制。

或者您能提供中国南方地区的西门子经销商联系方式，我们和他联系一下？

Thank you for your reply. I provided you with a picture. You said that the line is wrong, which means that we have to use this one-to-two connection line to connect? Second connection mode according to instructions?

So are we going to prepare K1D140 this module? Two routes are connected to fire engine at the same time?

If it is a simple cable problem, we have tried to customize this through Taobao merchants do you have any necessary technical parameters for the 14-pin cable? We are now pressing the 14pin interface, 2. 5mm line spacing standard to customize.

Or can you provide a Siemens distributor in South China, and we will contact him?
