The GCM48 is a general-purpose control module with six CAN buses, two LIN masters and one LIN slave, and configurable discrete inputs and outputs, including analog inputs, frequency inputs, a wake input, low-side driver outputs and an H-bridge driver output.
The GCM48 is one of the Raptor rugged production controllers that use a software development process based on MATLAB/Simulink, known as Raptor-Dev. Raptor-Dev significantly speeds up algorithm development by using automatic integration and code generation. In addition, developers can quickly test application software using simulation and automated testing.
Frequently Asked Questions (FAQ)
Q: How do I fix LIN1 and LIN2 communication issues?
A: It has been discovered that in the 2002 and 2008 revisions the LIN1 and LIN2 resources are swapped. Previous documentation was incorrect, and the datasheet now reflects the proper pin-out. If you are transitioning your system from a 2002 or 2008 to a 2104 and use LIN1 or LIN2, you will need to swap these pins.
Q: What is the baud rate for recovery of the GCM48?
A: Recovery procedure is CAN 1, 500K baud rate. The GCM48 boot procedure works at 500K baud only.
Q: Can I flash the GCM48 on different CAN buses?
A: The GCM48-1906 and GCM48-2002 variants of the GCM48 can only be flashed on CAN1 with a fixed address. The GCM48-2008 and GCM48-2104 support flashing on different CAN buses.
Q: What is new in the GCM48-2104?
A: The GCM48-2104 only utilizes 7 low-side outputs. In this variant, LSO6 is utilized for "Fuel Level Indicator" actuation and is not able to function as a typical LSO.
Q: How much current does the module sink when hibernating? How much does it sink when not hibernating?
A: When WAKE_INPUT1 is low, the module draws about 550uA. When WAKE_INPUT1 is high (module is on), it draws about 120mA.
Q: Are there other user tips and Q&As on Raptor ECUs published?
A: Yes, see the knowledge base on the support portal. https://neweagle.net/product-support/
Q: Can I purchase a 2008? Are these modules available?
A: No, this is not a stocked item, but it is available with a large production order. Contact sales for more information.
