RS485 (RS485 201)
A full-duplex RS485 interface including a 120Ω termination resistor is provided with bit rates up to 200kb/s.
When not activated, the driver will be in the high-impedance state.
Specifications (Texas Instruments SN65HVD3082E):
Voltage at any bus terminal (separately or common mode): -7V..+12V
Driver output current: -60..+60 mA
Note 1: The internal eC-test-mate UART is shared between the UART test pins and the RS485 test pins.
Depending on the last configuration command, either the UART pins or RS485 pins will be active.
If the RS485 interface is inactive, the eC-test-mate's RS485 driver will be in the high-impedance state.
See section Serial Channel (UART 101) for the configurable parameters (baud rate etc).
Associated test command(s):
• CONFIG_RS485
• TRANSMIT_RS485
• RECEIVE_RS485
CAN (CAN 201)
An ISO 11898-5 compliant CAN transceiver interface with up to 1Mb/s operation is provided. The interface is
terminated with a 120 Ω resistor.
Electrical Specifications (Microchip MCP2562):
Absolute maximum voltage range: -58V to +58V
Dominant output voltage: CANH = 3.5V, CANL = 1.5V
Recessive output voltage: CANH, CANL = 2.5V
Short circuit output current
CANH: -120..+85mA
CANL: +75..+120mA
Note: no other protection is added to the CAN bus.
Supported baud rates are as follows:
• 20 kbps
• 25 kbps
• 50 kbps
• 80 kbps
• 100 kbps
• 125 kbps
• 200 kbps
• 250 kbps
• 500 kbps
• 625 kbps
• 1 Mbps
Associated test command(s):
• CONFIG_CAN
• TRANSMIT_CAN
• RECEIVE_CAN
