im looking for an old doc regarding interfacing with old VE.9Bit Devices
It is referenced in an stil lavailable document about interfacing with an mk2 adapter
For communicating with older (VE 9-bit RS485) products, refer to “VE - Interfacing with the Phoenix Product Range”.
i know old devices can not communicate with venus but i also know old devices can talk to the current victron config 3 app through an mk2 adapter talking ve.9bit.
i have an old multi around where i can configure and connect trough the current victron config 3 app with an mk2.2b usb to serial adapter (for communication handling see the linked pdf chapter 3.4.
with the old doc i hope to get more insight about the communication to create an open source driver for venus integration in combination with an mk2 adapter.
any help/info is greatly appreciated, victron won't supply the old doc sadly.
if anybody could send me the doc i would be very thankful -
