MaE Model Number: 16360IP
These are two big panels, each one providing 8 red and 8 green numbers of 3 digits of 7-segment displays.
Technical data: Dimensions: 775x480x85mm, weight 11kg. Digits: 16 groups of 3 digits, 60mm height. Power requirements: 230VAC 50Hz 100W. Data link: IEEE 802.3 10MB/s ethernet link. Protocol: proprietary MaE/Fobos 1.0 over port 1636.
These “Counter Panels” have been developed for the easySagra project.
We needed a way to display the number of ordered articles (thus “counter”) in two different panels.
A TV flat panel was a direct solution, however not the best. Main requirements were:
Entire development has been made using Open Source Software. Exception for the initial sketch, made using google sketchup in wine environment.
Chassis has been designed using QCad. Main issues: easy assembly and disassembly, sufficient air flow, mounting points for all the contents.
Each couple of displays (red and green for simplicity), is provided by a separate PCB.
PCBs have been designed using gEDA. Then have been realized by professional service.
An ethersex based board have been used as main board and ethernet interfacing. A simple module has been written to drive display boards.
Two phases:
