Microhard Systems P900 - Network ID;Address; Unit Address; Hop Pattern; Output Power

© Microhard Systems Inc. Confidential 86
1 in PP/PMP
1-FFFF in MESH
6.0 Register/Command Reference
Change the default value
for the Network ID to
something unique for your
network. Do this for an
added measure of
security and to
differentiate your network
from others which may be
operating nearby.
All modems in a given network must have the same Network Address. This
unique network address is not only a security feature for a particular network,
but also allows other networks - with their own unique network address - to
operate in the same area without the possibility of undesired data exchange
between networks.

Values (0 - 4,294,967,295)
S104 Network Address (ID)
Values (0 - 49)
S106 Hop Pattern
0
This register, together with the Network ID and the Hop Zone, determines the
Hopping Pattern or table on which the P900 will frequency hop. This register
must be set to the hop pattern of the immediate Master/Repeater, unless
roaming is used.
Values (1 - 65534)
S105 Unit Address
Unit address in PP and PMP modes, or in MESH if S87=1. The unit address is,
and must be, a unique identifier of each modem in a network. The address
value is 16-bits in length.
The Master has by default, and must retain, a unit address of 1; 65535 is the
broadcast address.
S108 Output Power
20 (100)
21 (125)
22 (160)
23 (200)
24 (250)
25 (320)
This setting establishes the transmit power level which will be presented to the
antenna connector at the rear of the modem.
Unless required S108 should be set not for maximum, but rather for the
minimum value required to maintain an adequate system fade margin.
FCC regulations allow
for up to 36dBi effective
isotropic radiated power
(EIRP). The sum (in
dBm) of the transmitted
power, the cabling loss,
and the antenna gain
cannot exceed 36dBi.
Values (dBm (mw))
