Warranty Microhard Systems Inc. warrants that each product will be free of defects in material and workmanship for a period of one (1) year for its products. The warranty commences on the date the product is shipped by Microhard Systems Inc. Microhard Systems Inc.’s sole liability and responsibility under this warranty is to repair or replace any product which is returned to it by the Buyer and which Microhard Systems Inc. determines does not conform to the warranty.
nMIMO2458 Regulatory Requirements WARNING: To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 23 cm (33cm IC) or more should be maintained between the antenna of this device and persons during device operation. To ensure compliance, operations at closer than this distance is not recommended. The antenna used for this transmitter must not be co-located in conjunction with any other antenna or transmitter.
nMIMO2458 Exigences Réglementaires WARNING: Pour satisfaire aux exigences de la FCC d'exposition RF pour la base et mobiles sur une distance de séparation de 23 cm (33cm IC) ou plus doit être maintenue entre l'antenne de cet appareil et des personnes lors de fonctionnement du dispositif. Pour assurer la conformité des opérations au plus près que cette distance n'est pas recommandée.
Co-Location with Cellular Modems The maximum calculated MPE ratio for the EUT with 2 dBi dipole antenna is 0.238, this configuration can be colocated with other antennas provided the sum of the MPE ratios for all the other simultaneous transmitting antennas incorporated in a host device is < 1.0 - 0.238 < 0.762.

2. General 2.0 Product Overview The nMIMO2458 is a high-performance embedded wireless data transceiver. Operating in the 2400 – 2483.5 MHz or 5725 – 5875 MHz ISM bands (selectable), this spread-spectrum module is capable of providing reliable wireless data transfer between almost any type of equipment. The small-size and superior RF performance of this module make it ideal for many applications.
TDMA (time division multiple access) support, allowing multi-slave access in point-to-point mode. roaming ability, allowing repeaters and slaves to resynchronize with a new master if the synchronization pulse from the original master is lost. While the typical application for the nMIMO2458 is to provide a short- to mid-range wireless communications link between DTEs, it can be adapted to almost any situation where an asynchronous serial interface is used and data intercommunication is required. 2.
3. Installation 3.0 Overview The nMIMO2458 complies with FCC part 15 at the modular level for operation in the license-free 2400-2483.5 MHz or 5725 – 5875 MHz ISM bands. This chapter provides guidelines for installing and deploying equipment which incorporates the nMIMO2458 module. 3.
Figure 1 Gain Calculation The power level has been set to 30dBm (1W) on the transmitter, and the receiver sensitivity for the nMIMO2458 is -108dBm. System gain would be calculated to be: 30 – 0.49 + 2 + 2 – 0.49 + 108 = 141 dB.
Once the equipment is deployed, you can verify the signal strength by entering into Command Mode and reading Register S123. This register provides the average signal strength in dBm. The minimum strength for communication is roughly -108dBm. For consistent reliable communication, you should try to deploy the equipment such that signal strength exceeds -90dBm. 3.2 Antennas and Cabling This section describes the recommended procedure for installing cabling and antennas for use with the nMIMO2458 module. 3.
3.2.2 Antennas WARNING: MAXIMUM EIRP Up to 31.51 dBm effective isotropically radiated power (EIRP) in 2.4 GHz Band. Therefore, the sum of the transmitted power (in dBm), the cabling loss and the antenna gain cannot exceed 31.51 dBm with respect to the isotropic radiator. Direct human contact with the antenna is potentially unhealthy when the nMIMO2458 is generating RF energy. Always ensure that the nMIMO2458 equipment is powered down during installation.
A. Approved Antennas This radio transmitter (IC:3143A-15NM2458) has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device.
