7.1.1 HOP CHANNEL
Hop Channel
may be set from 1-32 using the ST-72 keypad and assigns the pseudo-
random radio frequency hopping pattern. A transceiver will not go
InRange
of or
communicate with a transceiver operating on a different Hop Channel .
7.1.2 SYSTEM ID
System ID
may be set from 1-255 using the ST-72 keypad and is similar to a password
character or network number and makes network eavesdropping more difficult. A
transceiver will not go in range of or communicate with a transceiver operating on a
different
System ID
.
7.1.3 MODE
Mode
may be set for
CLIENT
or
SERVER.
For a single ST-72 communicating to up to
64 battery powered ST-48/RF transceivers,
Mode
must =
Server
. To prolong battery
life, ST-48/RFs sleep most of the time and therefore may not be
Servers
. If an
application calls for multiple ST-72 locations, only one may be set for
Server
and all
others must be
Clients
. This single Server transmits a beacon which all of the network’s
Clients synchronize to. ONLY ONE SERVER PER NETWORK.
7.2 WIRELESS MONITOR MODE
Wireless Monitor mode is exclusively for wireless communication to our ST-48/RF
wireless sensor transmitters (please visit ST-48/RF ). In Monitor mode the radio
connects to the ST-72’s communication port and receives input data from up to 64 ST-
48/RF sensor transmitters. Wired and wireless inputs may be mixed between the ST-
72’s 64 channels so it is possible to also accept wired signals from analog input option
PCBs described in
section 3.2 .
Use the WIRELESS MONITOR setting shown in Figure 7-3 ONLY FOR
COMMUNICATION TO ST-48/RF WIRELESS TRANSCEIVERS. See section 7.4 for setting up
wireless networks with other Modbus slave devices.
ST-48/RFs transmit 200 counts for 0% and 1000 counts for 100% full scale readings so
Input Min/Max menu values should be 200 & 1000. The Remote ID menu entry must
match the
Remote Id
address setting in the ST-48/RF providing data to this ST-72
channel.
Input Req
is typically set to VALUE but also allows a
Battery Voltage
entry
into this field. Entering
Battery Voltage
causes the channel to display (and alarm)
from battery voltage levels at this ST-48/RF. Voltage level of the 3.6 volt lithium battery
in this ST-48/RF is also displayed on this screen.
