DWE-DLM1 Transceiver Module
Regulatory Compliance
This section summarizes the responsibilities and actions required of the
manufacturer (Drum Workshop) to incorporate the DWE-DLM-1 module device into
their products. In certain situations, and applications, these “Host” products
will require additional FCC, ISED or other regulatory approvals prior to sale
or operation.
Appropriate instructions, documentation and labels are required for all
products. For more information concerning regulatory requirements, please
contact Drum Workshop and or a regulatory test lab.
FCC Certification and Important Information for the Integration of Module
This module has been granted limited modular approval. Drum Workshop is the
only authorized manufacture that can use this module for integration in to the
following final DWe products, DWE-DT1, DWE-CT1 & DWE-DH1, if they meet the
following conditions;
- The host product with the module installed must be evaluated for simultaneous transmission requirements.
- The user’s manual for the host product must clearly indicate the operation requirements and conditions that must be observed to ensure compliance with current FCC/ISED RF exposure guidelines.
- A label must be affixed to the outside of the host product that includes the following statement
o “Contains FCC ID: 2A9KBDLM191695”
o “Contains IC ID: 29868-191695”
o Along with the appropriate host name
The DWE-DLM1 module has been tested under FCC Part 15 Subpart C 15.247 for Intentional Radiator, FCC CFR 47 Part 15 Subpart B for Unintentional Radiators, FCC CFR 47 Part 1.1310 for MPE/RF Exposure and KDB 558074 D01 v05r02 for compliance on DTS, FHSS, HSD operating under section 15.247. All testing has confirmed compliance with the above stated regulations.
Drum Workshop has not approved any changes or modifications to this device by
the end user. Any changes or modifications could void the user’s authority to
operate the device/host.
FCC Module Labeling
If the FCC ID of the module is not visible when installed in the host
platform, then a permanently attached or marked label must be displayed on the
host unit it’s self-referring to the module as;
- “Contains FCC ID: 2A9KBDLM191695”
Also listed in the end user manual the following statement should be
placed.
This device complies with Part 15 of the FCC Rules. Operation is subject to
the following two conditions: (1) This device may not cause harmful
interference, and (2) This device must accept any interference received,
including interference that may cause undesired operation.
End Product Labeling for FCC:
When the module is installed in the host device, the FCC/IC ID label must be
visible through a window on the final device or it must be visible when an
access panel, door or cover is easily re-moved. If not, a second label must be
placed on the outside of the final device that contains the following text:
“Contains FCC ID: 2A9KBDLM191695”
FCC Part 15 Statement (Only Include if FCC Part 15 is Required on the End
Product):
Note: This equipment has been tested and found to comply with the limits for
a (OEM to insert device type: Class A or Class B) digital device, pursuant to
Part 15 of the FCC Rules. (OEM must follow Part 15 guidelines (§15.105 and
§15.19) to determine additional statements required in this section for their
device class)
Radiation Exposure Statement for FCC:
This device complies with FCC radiation exposure limits set forth for an
uncontrolled environment. In order to avoid the possibility of exceeding the
FCC radio frequency exposure limits, human proximity to the antenna shall not
be less than 20cm (8 inches) during normal operation.
This transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter.
This device complies with Part 15 of the FCC Rules. Operation is subject to
the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
ISED Statement and Labeling: This device complies with ISED’s license-
exempt RSSs. Operation is subject to the following two conditions: (1) This
device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired
operation.
A label containing the ISED Certification number must be permanently affixed
to the exterior of the host device into which the DWE-DLM1 module device is
installed. The label may also be under a panel or battery pack if it is
readily accessible and cannot be separated from the host device itself. The
label must contain a statement similar to the following; “Contains IC:
29868-191695” and show appropriate host name.
Important Safety Information
The following information applies to the devices described in this manual. Always observe all standard and accepted safety precautions and guidelines when handling any electrical device.
- Save this manual: it contains important safety information.
- Do not expose the DWE-DLM1product to open flames.
- Ensure that liquids do not spill on to the devices.
- Do not attempt to disassemble the product: Doing so will void the warranty. This product does not contain consumer-serviceable components.
Product Overview
The DWE-DLM1 transceiver module can be installed into three DWe host devices,
the DWE-DT1, DWE-CT1 and the DWE-DH1. In its basic form it is the wireless
conduit for midi and telemetry data. The DWE-DLM1 transceiver is used to
digitize analog voltage inputs from multiple analog sensors and then convert
these signals into digital information packets via an MCU. The data is then
transmitted on a carrier frequency as needed in the 2400-2483.5 MHz ISM band
using GFSK modulation at ~1Mbps data rate at10mW RF output power. After the
sensor information has been transmitted the DWE-DLM1 it is then put into a
receive mode and searches for an acknowledgment signal from its “paired”
device.
The DWE-DLM1 transceiver module can also be installed into devices used to
receive these digitized sensor signals and send back an acknowledgement
signal, such as the DWE-DH1. Using all the same data rates, modulation, RF
power level and frequency band as described above. In this mode the DWE-DLM1
collects the incoming data and sends it out via USB or other communications to
an interpretation device, such as a PC or other intelligent devices, that can
interpret the info.
The communication scheme is as such that the sensor collection data is
transmitted on one frequency and the acknowledgments are sent on a second
frequency. An example of this is the current usage of 4 channels, thus
allowing 4 simultaneous operations of systems, see the frequencies used
currently below.
- ch1 2402MHz 2423MHz
- ch2 2426MHz 2448MHz
- ch3 2451MHz 2472MHz
- ch4 2476MHz 2480MHz
Installation
This modular transmitter is only approved for use by the grantee in its own
products and is not intended for sale to third parties. These instructions are
intended for internal use only by an authorized representative of Drum
Workshop.
DWE-DLM1 Module
The DWE-DLM1 module RF section is covered by a sealed RF shield as shown below
and making it un-accessible to an end user.
- RF Shield:
a. The fence (bottom) of the shield has been soldered to the PCB.
b. The lid (top) of the shield shall be press-fit onto the fence and soldered to the fence (bottom) to complete the assembly of the DWE-DLM1 module making it un-accessible. The DWE-DLM1 module has two different types of antennas. There is one chip antenna that is a 2.4GHz antenna and one wire antenna. Both antennas are not to be modified in any way and must remain in the fixed location as installed by the manufactures. The diagrams below calls out the placement of the antenna as they have been manufactured and must remain this way when inserted into a host. The chip antenna of the DWE-DLM1 module is part of the PCBA assembly as shown in the below photo. Then the wire antenna is installed on to the DWE-DML1 module as shown below. Once the module is complete it is then installed by soldering on to the main PCBA of 1of 3 host boards. The DWEDT1(Host), the DWE-CT1 (Host) and or theDWE-DH1 (Host) as shown in the below photo
The module/host PCBAS are now ready to
install into their respective host mechanicals to complete final host
assembly.
