CAN, RS-485 and RS-232 interfaces
According to the datasheet pin assignment, the gateway has five CAN channels (CAN bus 0, 1, 2, 3 and 4); the CAN interface is 2.0 A/B (ISO 11898-2). In addition there are RS 485 (A and B) and RS232 (TX and RX) pins and, depending on the assembly options, a LIN bus pin.
Inputs and outputs
- 9 inputs/outputs in total: 5 inputs and 4 outputs. The inputs include 1 analog input (0…11.4 V) and four digital inputs; the DI_INT_1…4 pins are frequency inputs depending on the assembly variant.
- The digital outputs are specified for a 9-32 V switching voltage and a 0.02 – 2.5 A switching current; wire fault and short circuit diagnostics are possible via current sense.
- There is short circuit protection against GND and UB; the latch-off of the internal overtemperature protection can be realized by the software application.
Processor and housing
The datasheet names the S9S12XEP384 as ECU: 384 KB flash, 24 KB RAM and 4 KB EEPROM. The housing uses .070 Multilock 18P and 12P connectors and weighs 110 g.
Which gateway?
If you do not need five CAN channels, see the MRS Micro Gateway 32-bit with its 2 x CAN bus + 2 x LIN Master or 2 x I/Os variants. For other products: MRS Electronic, Control units.
EHR Elektronik develops application software for MRS Electronic control units.
MRS Universal Gateway 5x CAN – Data sheet (PDF)Frequently asked questions
How many CAN channels are there?
There are 5 x CAN interfaces: CAN bus 0, 1, 2, 3 and 4. The interface is CAN 2.0 A/B, ISO 11898-2.
Is there RS-485 or RS-232?
Yes. The datasheet pin assignment lists RS 485 (A and B) and RS232 (TX and RX) pins, plus a LIN bus pin depending on the assembly options.
Are there frequency inputs?
Yes, depending on the assembly variant the DI_INT_1…4 pins can be used as frequency inputs.
What current do the outputs drive?
The digital outputs are specified for a 9-32 V switching voltage and a 0.02 – 2.5 A switching current; short circuit protection is against GND and UB.
