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.Pin Function Defaults to1NC -2NC -3 RXD GPIO1_224 RTS# KEY_COL45 TXD GPIO1_236 CTS# KEY_COL57NC -8NC -9GND -10 +3.3V -

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.

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

THis exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: MCQ-50M1699/ IC: 1846A-50M1699”.RF ExposureRF 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 CanadaThis 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.
