ports of the RM-4. The serial data stream is demultiplexed, then ported into the IP layer and
transmitted to the NAQSServer in the form of UDP packets.
Field Deployment Procedure
Deployment
The following steps are suggested to start up the RM-4 after the installation of the sensor and
digitiser at the planned sites.
1. Choose a location for the RM-4. It should be located within 10m of its power source
and the LAN connection. If the RM-4 is equipped with a GPS engine, then its location
should also be such that a good antenna position (as discussed below) is available
within 10m. Place the RM-4 on any convenient surface where cables cannot be
accidentally dislodged.
2. Connect one of the standard LAN cables between the Ethernet port on the RM-4 and
the LAN.
3. If the RM-4 is to be used with digitisers, connect each RM-4-to-digitiser cable
assembly to the appropriate serial port of the RM-4. The RM-4-to-digitiser cable
assembly typically consists of a cable with a female DB-9 data connector, a DB-9 male
to RJ-45 adapter, and a standard LAN cable.
4. If the RM-4 is to be used with spread spectrum radios, connect each RM-4-to-radio
cable assembly to the appropriate serial port of the RM-4. The RM-4-to-radio cable
assembly typically consists of a cable with a female DB-9 data connector, a DB-9 male
to RJ-45 adapter, and a standard LAN cable.
5. If the RM-4 is to be used as an Internet timeserver, connect the GPS antenna to the
GPS cable and plug the cable into the coaxial GPS connector on the rear panel of the
RM-4. Position the antenna in a location with an unobstructed view of the sky.
6. Connect the power supply to the RM-4 power connector.
7. Ensure that the RM-4 status LED cycles between green, amber, red and off.
8. Read the RM-4 IP address off the as-shipped sheet, and ensure that the RM-4 can be
pinged at that address from another computer on the network.
9. Reconfigure the RM-4 to have the correct IP address required on the LAN before
adding another RM-4 to the same LAN. The rest of the RM-4 configuration can be
done once all of the RM-4s in the system are connected and operating.
