OEM719 Data Communication Specifications

OEM719 Data Communication Interfaces

COM1

Electrical format

LVCMOS

Data rates1Data rates higher than 115200 bit/s are not supported by standard PC hardware. Special computer hardware may be required for higher rates, including 230400 bit/s and 460800 bit/s.

2400, 4800, 9600 (default), 19200, 38400, 57600, 115200, 230400 or 460800 bit/s.

Signals supported

COM1_Tx, COM1_Rx

Electrostatic discharge protection

No

COM2

Electrical format

LVCMOS

Data rates1

2400, 4800, 9600 (default), 19200, 38400, 57600, 115200, 230400 or 460800 bit/s.

Signals supported

COM2_Tx, COM2_Rx

Electrostatic discharge protection

No

COM3

Electrical format

LVCMOS 2COM3 is disabled by default.

Data rates1

2400, 4800, 9600 (default), 19200, 38400, 57600, 115200, 230400 or 460800 bit/s.

Signals supported

COM3_Tx, COM3_Rx

Electrostatic discharge protection

No

CAN Bus

Electrical format

LVCMOS (requires external CAN transceiver)3CAN1 Rx and Tx signals are internally multiplexed with VARF and Event2, respectively. Both VARF and Event2 are enabled by default. To enable CAN functionality, the following commands must be issued before configuring the CAN1 port:   FREQUENCYOUT DISABLE   MARKCONTROL MARK2 DISABLEThese commands, together with the commands to configure the CAN1 port, can be saved using SAVECONFIG.

Data rates

250, 500 or 1000 kb/s

CAN Bus throughput is determined by slowest device on the bus

Signals supported

CAN1Tx, CAN1Rx, CAN2Tx, CAN2Rx

USB

Electrical format

Conforms to USB 2.0

Data rates

Full-speed (12 Mb/s)

Signals supported

USB D (+), USB D (-)
