By default, serial port 1 signals are configured as GPIO signals.
Serial Port 3, TTL Interface, X19
The serial (UART) port 3 interface is a TTL interface connected to a 2x5 pin, 2.54mm
connector, X19. The connector supports only TTL level signals.
The serial port 3 interface is connected to i.MX51 UART port 3.
Serial port 3 pins are allocated as shown:
By default, serial port 3 signals are configured to their respective GPIO or KEY_COL signals.
Serial port 3 is connected to the X19 connector and to the XBee module socket. Two jumpers
(J30 and J31) are used in the development board to select the connector where serial port 3
will be available. Refer to the “Jumpers” section of this document for more information.
By default serial port 3 CTS# signal is not connected to X19. A 0Ω resistor, R44, must be
manually populated to connect this signal to the X19 connector.

Supply Current
The following table provides current draw guidance utilizing the power management
capabilities of the module. The module variant used for the measurements works at 800MHz,
with 512 MB NAND Flach, 512 MB DDR2, dual Ethernet, WLAN, and accelerometer. A Windows
Embedded CE kernel with power management capabilities has been used to make the current
consumption measurements. A different kernel (Linux or Windows CE) with a different driver
configuration will show different current consumption values.
The ConnectCore for 1.MX51 module can be powered from an external battery (VLIO) or from
a battery charger (VCHRG). Current drawn by the modules is different depending on the
supply voltage used. The following tables show the current drawn by the module from the
two power supplies.
The current drawn by the module is highly dependent on the number and type of interfaces
used. To make some current measurements three different interface configurations have
been defined:
Parameter Symbol Min Typ Max Unit
Battery Input VLIO 3.4 3.7 4.8 V

The ConnectCore for 1.MX51 supports several power modes. The current drawn by the
module is highly dependent on the power modes. To make some current measurements five
different power modes have been defined:

Certifications
APPENDIX C
The ConnectCore for i.MX51 product complies with the following standards.
FCC Part 15 Class B
Radio Frequency Interface (RFI) (FCC 15.105)
The ConnectCore for i.MX51 module has been tested and found to comply with the limits for
Class B digital devices pursuant to Part 15 Subpart B, of the FCC rules. These limits are
designed to provide reasonable protection against harmful interference in a residential
environment. This 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. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference
to radio or television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try and correct the interference by one or more of the
following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
Labeling Requirements (FCC 15.19)
This device complies with Part 15 of 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.
If the FCC ID is not visible when installed inside another device, then the outside of the
device into which the module is installed must also display a label referring to the enclosed
ConnectCoreWi‐i.MX51

module FCC ID. THis exterior label can use wording such as the following: “Contains
Transmitter Module FCC ID: MCQ-50M1699/ IC: 1846A-50M1699”.
RF Exposure
RF Exposure considerations require that a 20 cm separation distance between users and the
installed antenna location shall be maintained at all times when the module is energized.
OEM installers must consider suitable module and antenna installation locations in order to
assure this in 20cm separation, and end users be also be advised to the requirement.
Modifications (FCC 15.21)
Changes or modifications to this equipment not expressly approved by Digi may void the
user’s authority to operate this equipment.
Industry Canada
This digital apparatus does not exceed the Class B limits for radio noise emissions from digital
apparatus set out in the Radio Interference Regulations of the Canadian Department of
Communications.
Le present appareil numerique n’emet pas de bruits radioelectriques depassant les limites
applicables aux appareils numeriques de la class B prescrites dans le Reglement sur le
brouillage radioelectrique edicte par le ministere des Communications du Canada.
The maximum antenna gain permitted in the bands 5250-5350 MHz and 5470-5725 MHz to
comply with the e.i.r.p limit is, according to RSS-210 section A9.2(2)
250mW conducted power
1.0W max EIRP
This limit is met with the highest gain antenna listed, antennafactor ANT-DB1-RAF-RPS.
The maximum antenna gain permitted in the band 5725-5825 MHz to comply with the e.i.r.p
limit specified for non point-to-point operation is, according to RSS-210 section A9.2(3):
1W conducted power
4.0W max EIRP
This limit is met with the highest gain antenna listed,antennafactor ANT-DB1-RAF-RPS.
OEM installers and users are cautioned to take note that high-power radars are allocated as
primary users (meaning they have priority) of the bands 5250-5330 MHz and 5650-5850 MHz
and these radars could cause interference and /or damage to devices operating in these
frequency bands.

Indoor/Outdoor
When the ConnectCore for i.MX51 module is installed in devices that can be used outdoors,
the channels in the band 5150-5250 MHz must be disabled to comply with US and Canadian
regulatory requirements. The OEM users are encouraged to inform end users of this
restriction as well.
