When Installing and Removing the MR8904 into and from the Memory
HiCorder
• To avoid electric shock accident, before removing or replacing an MR8904, confirm
that the instrument is turned off and that the power cord and connection cables are
disconnected. The mounting screws must be firmly tightened or the MR8904 and
the Memory HiCorder may not perform to specifications, or may even fail.
• To avoid the danger of electric shock, never operate the Memory HiCorder with an
input
module removed. To use the Memory HiCorder after removing an input mod-
ule, install a blank panel over the opening of the removed module.
Measurements made without a blank panel installed may fail to meet specifications
because of temperature instability within the input modules.
See: "3.1 Installing and Removing the MR8904 into and from a Memory HiCorder" (p.11)
Usage Notes
When Connecting the MR8904 and the Object under Measurement
This device is designed to collect messages being transferred on the CAN bus and to
send messages to the CAN bus. Do not connect it to anything other than a CAN bus.
In addition to damaging the Memory HiCorder, CAN Unit, and measurement target,
doing so may cause bodily injury.
Use of the CAN Unit may affect the operation of the CAN bus as well as systems connected to the CAN bus. The resulting operation may cause bodily injury or property
damage. V
ated systems before use.
• When connecting the MR8904 to a CAN bus, exercise care not to connect the power supply and ground lines backwards. Doing so may damage the MR8904 and measurement

• When measuring low-speed CAN or single-wire CAN bus
ground and measurement cable ground lines are not isolated. Wire the system so that no
potential difference occurs between the ground lines. Failure to do so may damage the

Transport and Handling
To avoid damage to the MR8904, protect it from physical shock when transporting and handling. Be especially careful to avoid physical shock from dropping.
This device may cause interference if used in residential areas. Such use must be avoided
unless the user takes special measures to reduce electromagnetic emissions to prevent inter
ference to the reception of rad
io and television broadcasts.

Usage Notes
1.1 Features
Product Overview Chapter 1
The MR8904 is an input module for Memory HiCorder that captures necessary data from CAN bus signaling and transfers analog or logic signals to a Memory HiCorder as waveform data.
• When you connect the Memory HiCorder to a PC with a USB cable, you can configure the MR8904
from the PC with the MR8904 CAN Editor application (the USB cable and application are included with
the Memory HiCorder).
• Up to 200 CAN definitions can be registered.
The MR8904 is a Memory HiCorder option. It should only be used when installed in a Memory HiCorder.
Supported models: MR8875

1.1 Features
Support for mixed recording
Used in combination with other Memory HiCorder optional input modules, the MR8904 can be
used to implement mixed recording of sensor data and control signals on a CAN bus as well
as signals that cannot be acquired on a CAN bus.
Ability to send data to the CAN bus
The MR8904 can send ACK responses to CAN messages as well as CAN messages themselves, allowing it to be used in simple
simulations.
Use of CANdb files

When an error is encountered, the port in question will enter ACK OFF mode, making it
unable to send messages or issue ACK responses.
The error state will return to normal after measurement completes.
When a port enters an error state, verify that the wiring and CAN communications conditions are correct.
