Telluscoder — Client Guide

1. Download & install

The apps for Windows, macOS and Android are available after you sign in to your customer page.

After signing in, download and launch the app. Android: allow installation from unknown sources if prompted. The programmer connects via USB (Android requires a USB-OTG adapter).

2. Step by step

1

Sign in

Open the app and sign in with the email and password you received from your administrator. The client then fetches your assigned firmware files from the portal.

2

Connect the programmer

Plug in the WRITE CODE BOARD programmer via USB. The client detects it automatically — status shows as Connected.

3

Insert the module

Place the SFP/QSFP module in the correct slot on the programmer (SFP vs QSFP/XFP). Push it all the way in.

4

Detect

Click Detect. The app reads the module identifier and shows the type (SFP, QSFP, QSFP-DD …) along with vendor and part number.

5

Select firmware

Pick the right file from the list of your assigned firmware files. Filter by module type to find it faster.

6

Program & verify

Click Program. The client writes the EEPROM, reads it back and verifies automatically. Green = done.

Frequently asked questions

The programmer isn't detected: Check the USB cable, try another port. On Windows you may need to restart the app after plugging it in. On Android a USB-OTG adapter is required.
I don't see any firmware files: Files are assigned per account by the administrator. If a file is missing, contact your admin to have it linked to your account.
Verification fails: Is the module in the correct slot? Try reinserting it and run again. Some modules require the right password/write-protection — the admin can configure this per customer.
Wrong password at sign in: Ask your administrator to reset the password in the portal (Accounts → Password).
