Non-Standard RS232C Port(DB-15 Female?)

Hello, to all.

I have faced a new problem, and will be thankfull if anyone help me.

As I have seen, on Rear Panel of Autoanalyzer Roche/Hitachi 902 there is 4 Ports, From J401 to J 404.

One is DB25M, On is DB9F, One is DB-15F and the last one is DB9-M. The Middle port (DB-15F) is marked with

Label "HOST". I have checked other ports and they have no compatible voltage with RS-232 Standard, So it seems that Roche/Hitachi has used a non-standard DB-15 F Port to communicate with Host Computer. Does anyone know

pin-assignment of this non-standard port? any help will be appreciated.

Best regards with special thanks to great Boss, Yeec!

That I do not know if 902 be a Chinese marketplace that you say 7020, but disregarding the standard being what interface may abide by RS232C, can links up coming reference operation instruction , 7020's interfaces are 25 injection's according to what I know.
我不知道你说的902是否就是中国市场的7020，但无论是什么样的接口都会遵循RS232C的标准的，可以参考操作手册来连接，据我所知7020的接口是25针的。

This is 7020's rear panels , has 5 interfaces , J400- - J404, J402 among them are that string , you have a look , not knowing to if follow one kind that you say.
这是7020的后面板，有5个接口，J400--J404,其中J402就是串口，你看一下，不知道是否跟你说的一样。

Dear Yeec. Thanks alot for your Help. Rear Panel of Hitachi/Roche 902 is EXACTLY the same as 7020 (I had a mistake, 902 also has 5 ports on rear panel, Excuse me).

I really will be thankful if you say me what is the Cable Order for connecting J402 of 7020 to Host RS232 Port.

Best regards. and thanks again for help.

7020's J402 are 9 injection interface of standard , are not the 15 injection that you say , perhaps being that way does not help you. However, operation instruction is listed in data that can have this interface , you check carefully.
