2. Initial Setup and Configuration
2.0 Unpacking and Inspection
The following items should be found in the shipping carton. Inspect the
contents for any shipping damage. Report damages or shortages to the
distributor from which the unit was purchased. Keep all packing materials in
the event that transportation is required in the future.
Package contents (normal distribution):
1 MHX-900 Wireless Modem module 1
2 Operating Manual (this document) 1
2.1 Additional Requirements
Since the MHX-900 module is a unique product in a class of its own, it will
communicate only with another MHX-900 module which has been
compatibly configured. Thus, at least two MHX-900 modules will be
required to establish a wireless communications link.
Additionally, the following requirements should be taken into consideration
when preparing to incorporate the MHX-900 module in new or existing
designs.
n
Relatively small footprint for the MHX-900 module ( e.g., 2.1”
W x 3.5” L x 0.8” H) on the OEM PCB.
n
Serial port and control signals from the host microprocessor.
See sample application schematics in Appendix C.
n
+5 Vdc supply from the host OEM electronics (+ 10%).
n
An external antenna (customer supplied).
2.2 Connectors and Indicators
The MHX-900 module connects to the host equipment by a dual row header
on the underside of the unit. This enables the MHX-900 module to be
directly soldered onto the host equipment manufacturer’s PCB.
The MHX-900 radio deck is attached via a 40 pin header soldered directly to
the PCB. The radio deck also has an antenna connector. A suitable antenna
must be used to ensure adequate performance of the MHX-900 module.
The MHX-900 module is equipped with status LEDs which show the current
operating mode for the unit. The LED signals also are also brought out to
external connectors to be monitored by the OEM microprocessor.
The output drive capability of any output signal pin is approx. 5 mA.
The pin description and location of the MHX-900 is shown on the following
page.
