UT10 Weather Station
There are five configuration options for the RF500M:
1. RF ID – Set the modem address with a value from 1–255. Each RF500M
in the network must have a unique RF ID.
2. CS I/O Settings – Set the CS I/O interface options. Choose the SDC
address that will be used to communicate with the datalogger or if a digital
radio is attached and this RF500M is used as an RF Base, select the
Connected to PC via SC532 option (requires an SC532(A) between the CS
I/O interface and the serial port of the PC). If using the Connected to PC
via SC532 option, make sure the RS-232 interface is not set as Connected
to PC.
3. RS-232 Settings – Set the RS-232 interface options. Choose whether the
RF500M will be connected to the PC with a null modem cable, if a digital
radio will be connected to the RS-232 interface, or it will be connected to a
datalogger. If using the Connected to PC option, make sure the CS I/O is
not set as Connected to PC via SC532.
4. Baud Rate – Set the baud rate for the RS-232 interface.
5. Sleep-Mode Enabled – Determine if sleep mode functionality will be
enabled for RF300 series radios. In all other cases, this setting will be
ignored.
Once the RF500M has been configured, it is ready to be deployed.
8.3.5.2 RF500M RF Base Station
When the RF500M is used in a base station configuration, the PC is attached to
the RS-232 port with a null modem cable. If a digital radio is being used on
the RS-232 port, the CS I/O port can be configured to communicate with the
PC but an SC532(A) and serial cable must be used between the PC and the CS
I/O port of the RF500M.
1. Connect the RF500M to 12 V and ground. Connect the radio to 12 V,
ground, and the RF Modem (RF500M).
Radio transmission without an antenna connected can
damage the radio.
2. Mount the base station antenna in a location that is higher than any
surrounding buildings or obstacles.
3. After the antenna is mounted, connect the coax cable between the antenna
and radio.
4. Connect a large gauge (approximately 8 AWG) copper wire from the
antenna to a good earth ground. This is for lightning protection. This is
required for any antenna, especially if the coax cable from the antenna
goes inside a building.
5. Connect a null modem cable from the computer serial port to the RS-232
port of the RF500M. If a digital radio is being used on the RS-232 port, an
SC532 and serial cable can be used between the PC and the CS I/O port of
the RF500M. Set the appropriate configuration options in the RF500M
with Device Configuration Utility depending on the port connected to the
PC.
