backlight of sigma version

I cant see backlight in my signotec sigma pad. Version is ST-ME105-2-U100. How to know that this sign pad is equipped with backlight

Dear Mr. Sharma,
Thank you for your inquiry.
The backlight of our signotec Sigma devices is optional and only included in the ST-BE105 models. Not in the ST-ME105 models.

We bought 3 Sigma pads for signing some documents in a specific application, but in this application we have a signature field which is taking the mouse pad function ( from laptop ). Do you think that it is possible to adapt the Sigma Pad to have mouse pad function [more]

Hello, you must ask your manufacturer from your specific application. The signature pads never emulate a mouse input for security reasons.


I have 2 models of sigma signature pad. one is "Rev.: C" and another one "Rev.:E"
Rev.: E is working but I have problem with Rev.: C, because it is not compatible with my software. Is there any way to solve this problem?
And what is the difference between these versions?

von Costumer | 17.02.2019 09:31

Hello, you have to update the SDK "signoPAD-API". All revisions are compatible. If a newer pad doesn't work it is related to the fact that you are using an SDK which is about 6 years old. We recommend to update...


I have a web based system which generates a pdf. I want to use signotec to digitally sign this document. How do I do this? Any help would be most welcome. Once rolled out at the client. The client will need to buy 1 signature pad per branch. around 10 in total. Thanks for your help

Hi, if you want to digitally sign PDF documents, we recommend to use our "signoSign/Universal", which is also a Web-based solution. You will find more info within the product description.

Is it posible to use this item Ethernet to USB Adaptor ST-TCPIP-USB-CONV-2 ? For TSE (

I can not find the product shown in the video there [more]

von daniel DUCTEIL | 03.04.2017 15:48

Hi, you can use the Sigma with an internal USB-Serial-Converter which ends with FT100. The FT indicates the converter.

The TCPIP-USB-CONV-2 is a complete different scenario to connect a USB signature pad (ends with U100) to the network and address it via a TCP/IP address.


Is it possible to use it with Terminal Server ?
I mean remote the information with the network.


von daniel DUCTEIL | 31.03.2017 19:20

Yes, you can use it with a Terminal Server for sure. We provide different solutions. Because of limitations of the TS it is needed to communicate with the signature pad via a (virtual) Com-port: We have a hardware based internal USB-Serial-converter, a VCOM-Driver for o [more]

What type if TIFF file is the file format of the signature.
Example:Group-4 Compression

von Laurie York | 22.04.2015 22:53

Hi, it is a TIFF with LZW compression. Group 4 (Fax) is not sufficient because we show the pressure (variable line width with shading) in the image. Such a high quality is not possible with G4. BTW: You can test it with the signotec pad capture control demo which is par [more]
