MHX-900 Operating Manual: Chapter 2 Initial Setup and Configuration

2.3 Configuration
Prior to establishing a wireless link, each MHX-900 module that will
participate in the link must be correctly configured for compatibility and for
the desired mode of operation.
The two most common types of networks used are:
n
Point-to-point : A Master station communicates with a single
Slave station.
n
Point-to-multipoint : A Master station communications with
two or more Slave stations.
Within any network, the Master will communicate only with Slave(s)
assigned to the same network. Similarly, a Slave will only communicate with
the Master of the network to which it is assigned.
2.3.1 Quick Start Approach
The minimum configuration requirements for point-to-point and point-to-
multipoint are summarized below.
These requirements will get you started
and only ensure that a link can be established, but do not necessarily provide
the best performance
; optimization of the communications link is discussed
in later sections.
A. Point-to-Point
To establish a point-to-point communications link, the following requisites
must be satisfied:
n
The Operating Mode for one modem must be configured as a
“ Master - Point-to-Point ”, and the other as a “ Slave - Point-to-
Point ”.
n
The Wireless Link Rate for both modems must be the same.
n
The Network Address assigned for both modems must be the
same.
n
The Unit Address assigned for both modems must be the same.
n
The same Hopping Pattern must be selected for both modems.
n
The same Hopping Interval must be selected for both modems.
n
Both modems must use the same Encryption Key .
