2.2.1. Main connector
SBG Systems has selected a specific connector designed for high reliability. The main connector provides
access to all Ellipse Micro features through a modular way. It provides:
●
The main serial port (PORT A) that supports full-duplex communication. It operates by default in RS-
422 in the versions M1, or in RS-232 on M2 devices
●
An auxiliary RS-232 port (PORT E), available only when Ellipse Micro is operated in RS-232
●
One CAN 2.0A/B connection that supports up to 1 Mbit/s data rate used to output data
●
Two multi-function input/output pins that can be used for:
●
Clock synchronization or event marker input pins
●
Single channel Odometer input
●
Synchronization output signals for time stamping and to trigger some equipment.
2.2.1.1. Connector specifications
The main connector uses a 10 ways Harwin Gecko connector. The exact receptacle reference is: G125-
FS11005L0P.
The Ellipse Micro connector will mate with the cable mounted reference G125-3041096L4 (Harwin). Don't
forget that this reference doesn't include the contacts.
For lowest cost and high volume integration, SBG Systems recommends the use of a board to board
connector: G125-MS11005L0P (surface mount) or G125-MV11005L0P (through hole mount).
For cable connections, it is also possible to purchase cable assemblies from Harwin: G125-MC21005L4-0150L
and G125-MC21005L0-0150M. For shorter lead time, SBG Systems provides the following cable assembly
reference CA-ELI-M-OW-0.25M.
Other plugs with right angle or other options may be found if required.
