The hexadecimal number system is represented and work using the base of 16. That is content number "0" - "9" and other "A" - "F" it describes 0 to 15. Decimal has only 10 digits 0 to 9. So, Hex is used "A" - "F" for the other 6 characters.
For example, Hex(Base 16) used D for 13 as a decimal(base 10) value and binary 1101.
Each Hexadecimal code has 4 digit binary code.
The hexadecimal number is widely used in computer systems by designers and programmers.
Hexadecimal to Decimal Conversion, For Hex we select base as 16. Multiply Each Digit with a corresponding power of 16 and Sum of them.
Decimal = d X 16n-1 + ... + d X 162 + d X 161 + d X 160
For, 1A in base 16 need to power of 16 with each hex number and Sum of them.
Here, n is 2.
1A = (1 X 16n-1) + (A X 16n-1) = (1 X 161) + (10 X 160) = (1 X 16) + (10 X 1) = 16 + 10 = 26
Let's start Hexadecimal Decode. Here, n is 1.
0.5 = (0 X 16n-1) + (5 X 16n-1) = (0 X 160) + (5 X 16-1) = (0 X 1) + (5 X 0.0625) = 0 + 0.3125 = 0.3125

COGO Functions: Includes built-in Coordinate Geometry (COGO) features for processing land surveying data directly within the application.
Data Organization: Allows users to create folders, manage project references, and edit field data (such as point names or codes) before exporting to CAD software. System Requirements
Because Prolink 1.15 is an older application, it has very modest hardware requirements but may require compatibility settings on modern operating systems: How to Install ProLink 1
Installing software from 2012 on a modern OS requires a few tweaks. Follow this guide:
| Problem | Solution | |--------|----------| | "COM port not found" | Install USB-to-serial drivers. Check Device Manager for port number. | | "Instrument not responding" | Lower baud rate to 4800. Check cable integrity. | | "File corrupt" error | Re-download the installer. Disable antivirus during transfer. | | Blank screen on Windows 10/11 | Run in 256-color mode (Compatibility settings). | | Cannot save to DXF | Install MS Excel or use a free CSV converter. ProLink 1.15 requires Excel components for some exports. |
ProLink 1.15 was designed for Windows XP/Vista/7. However, it can still run on newer Windows versions with tweaks:
.exe or setup.msi → "Run as administrator."ProLink 1.15 works with:
It does not work with the latest Sokkia iX or SONNIS series (those require newer software).
Sokkia ProLink is a PC software utility designed to manage coordinate data, upload job files, download raw measurement data, and configure Sokkia total stations (such as the SET, SRX, and DX series) via serial connection (RS-232C) or USB. It acts as a file manager and data converter, translating raw field data into usable formats like CSV, DXF, or TXT for office software (e.g., AutoCAD, Civil 3D, or GIS applications).
Version 1.15 is particularly notable because it strikes a balance between stability and compatibility—supporting older Windows environments (XP, Vista, 7) while offering essential features without the bloat of newer, paid subscription-based tools.
Before we dive into the download process, it is critical to understand what this software actually does. ProLink is not a CAD program or a full data processing suite. Instead, it is a communication and file management utility designed specifically for Sokkia surveying instruments.
