Functional Description
The S1-A-7001 is a RS232 to CANbus adapter which operates at up to 1Mbps on both RS232 and CANbus
interfaces.
Each S1-A-7001 contains a small internal electronic circuit board mounted inside of a plastic case capable
of withstanding industrial temperature ranges. The integrated electronics include a Microchip PIC with the
ECAN controller. LEDs give a visual indication of the CANbus status.
The S1-A-7001 requires an external power supply with an input voltage range of +6VDC to +15VDC.

Its small size allows the S1-A-7001 to be used in a variety of applications, from a portable adapter to
accompany a laptop to permanent installations in industrial and commercial locations.
The enclosure incorporates a DE-9S connector that allows connection to an RS232 device in DTE
configuration by using a straight-through cable. CANbus signals are available on an industry-standard
DE-9P connector conforming to the CAN-in-Automation (CiA) DS102-2 pin-out. The maximum CANbus
data rate is 1Mbps. RS232 data rates range from 2400bps to 460.8Kbps and 1Mbps.
Communications are accomplished with ASCII commands to the CAN controller. The ASCII commands
are listed in
