Ha, sucess. I ordered generic type of FS LR (SFP-10GLR-31). After 10+ days of brute forcing I found manufacturer password for it, check screenshot below. Everything is working with this password, I can change manufacturer name, s/n etc. Just ignore start range - my PC updated and restarted during br...

I'm sorry for late reply, I missed notification for this thread You can read any page using SFP[USER], please check this thread viewtopic.php?f=32&t=529 But if it not follows MSA standard it may be no access to these pages

Ok, it may be DC/DC converter faulty or driver on OLED. Please replace this chip marked with pins 6-10, it's MP1541 / MP1541DJ in SOT23-5 package: https://www.monolithicpower.com/en/mp1541.html

Seems like DC/DC converter on OLED board is faulty or microprocessor on OLED board (chip on glass - can not be replaced) is faulty and drain to much current. Please measure voltages on 2 DC/DC converters, I marked 10 points:

Display connector in utcomp pin1 is ground and pin 2 is VDD - this is the same voltage level as for DS18B20 sensors (about 5.0V when ignition switch is ON). If you have missing voltage on A18 and it's fine on A6 it means that internal power supply is working fine, voltage on A18 is missing from anot...

I updated first post with information about memory map for new CMIS standard based on OIF CMIS rev5.2 specification (from 2022). It's used mainly for multiline transceivers such as QSFP-DD SFP-DD and OSFP. REVELPROG-IS software will also be updated - new standard is already implemented and it will b...

Cisco jest dość specyficzne i potrzebuje unikalnego podpisu dla każdego S/N, niestety sam nie posiadam takiego kalkulatora ale temat jest poruszony na zagranicznej części forum gdzie są osoby, które to ogarniają, odsyłam tutaj: https://forum.reveltronics.com/viewtopic.php?f=22&t=949&hilit=ci...

REVELPROG-IS programmer supports MSA compliant transceivers. MSA (Multi-Source Agreement) is an agreement between multiple manufacturers. It defines standards for form factors, electrical and optical interface for various transceivers. From programming point of view we are interested only with manag...

It's 100% normal, it's designed feature. These Adc inputs are very sensitive, when it's not connected it measure voltage in air (usually noise), when you put your fingers on it it can measure your pulse. Just connect voltage signal from sensor to this input and it will be stable as stable is your si...

Buzzer should work. Please disconnect display and check buzzer and buttons (you should hear clicks). If buzzer and buttons are working, you can connect new display to your module because probably only display is damaged. But first make sure that you have not more than +5,2 on power lines (e.g. DS18B...
