equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residen-
tial area is likely to cause interference in which case the
user is required to correct interference at his expense.

ifications when shielded cables are used for external wiring.
We recommend the use of shielded cables. This kind of
cable is available from Advantech. Please contact your local
supplier for ordering information.
PCM-3680 is a special purpose communication card
that brings the Control Area Network to your PC.
With the built-in CAN controller, the PCM-3680
provides bus arbitration and error detection with
automatic transmission repeat function. The on-
board CAN controllers are located at different posi-
tions in the memory. You can run both CAN control-
lers at the same time, independently. The PCM-3680
operates at baud rates up to 1 Mbps and can be
installed directly into the expansion slot of your PC.

2 PCM-3680 Startup Manual
Card Configuration
The PCM-3680 has two ports, each with one jumper.
The jumpers set the IRQ for the ports, which can be
configured separately. A DIP switch sets the memory
base address for each port. The following chart shows
the function of the jumper and the switch (see the previ-
ous page for jumper and switch locations).
Default Settings
• Port 1 is set for COM1 (IRQ=12, Memory address =
DA00:0000).
• Port 2 is set for COM2 (IRQ=15, Memory address =
DA00:0200).
If you need to change these settings, see the following
sections. Otherwise, you can simply install the card.
Note that you will need to disable your CPU card's on-
board COM ports, if any, or set them to alternate
addresses/IRQs.
Jumpers and Switches
Jumpers JP1 and JP2 set the interrupts for Port 1 and
Port 2, respectively. You can choose any IRQ from 3 to
15, except 8, 13 and 14. When you choose IRQs, make
sure they are not used for other cards in the system. The
following figures show the card's default settings.
Memory Base Address (SW1)
The memory base address for the PCM-3680, which
requires 4 KB of address space, is made up of the mem-
ory segment and its associated offset. The address for
the memory segment is set through SW1, a six-position
DIP switch. You can choose any base address from
C800 to EF00. The following table shows the DIP
switch settings and the corresponding base addresses.
Memory Area
Once the memory segment for the base address is
selected, the offset will be automatically assigned for
Port 1, Port 2, and hardware reset. The following table
shows the base addresses of the CAN controllers.

PCM-3680 Startup Manual 3
Software Overview
The PCM-3680 comes with a utility disk with the fol-
lowing software capabilities:
• CAN controller configuration
• CAN transmission monitoring
• Terminal emulation
Main Menu
Run DataMonitor at the DOS prompt. DataMonitor's
main menu screen will appear as shown below
The main screen consists of:
A. Menu bar: Lists the available functions. From the
main menu you can select Configuration, Monitoring,
and Terminal.
B. Monitor screen: Shows monitored data, including
message index, CAN device ID, data length, and data.
C. Status fields: Display the status of the two ports
and the status register of the CAN controllers.
D. Online help/message bar: Shows various key
commands and states the function of the currently high-
lighted item.
Configuration
Before you transmit a CAN object, you must configure
the CAN controller by selecting the <Config> menu
with the cursor keys and pressing <Enter>. The Config-
uration function determines the ports to be used and
their communication parameters.
The port configuration window is shown below.
The parameters below need to be configured for each
CAN controller:
Address segment: The base address (address segment)
is normally adjusted during the installation process. The
selection of the address segment needs to be the same as
that of the hardware configuration.
Port: Select the port you want to configure.
Baud rate: The baud rate must be coordinated with the
CAN network. Choose the appropriate one from the list
of baud rates.
Acceptance code: Specifies the value of the 8 most sig-
nificant bits of the identifier (ID10 ... ID 3)
Acceptance mask: Specifies the bit positions which are
"relevant" for acceptance filtering.
Note: The acceptance code and acceptance mask are
configured through eight digits (1 digit per bit) using 0
or 1.
Example: Acc Code = 11111111
Acc Mask =11111111
The shown acceptance filter will accept every received
message.
Interrupt: Sets the interrupt for each port. Be sure that
this setting matches the IRQ already selected for the
PCM-3860, which accepts values between IRQ3 to
IRQ15, except 8 and 13.
Running mode: During the normal configuration and
communication process, select Normal Mode. When
the system fails, you can hit <Enter> to reset the CAN
controller. Hit <Enter> again to further execute your
configuration.
Monitor: Select the port to be monitored from the
<Monitor> pull- down menu. Press F3 to start and stop
the monitoring process.
