Using An Rf Modem - RBR 1050 Series User Manual

Note:
The seal for the underwater connection depends upon two O-
rings: one is attached to the connector and the other to the
bulkhead. There are two common difficulties relating to these O-
rings:
1. If the O-ring on the plug is not well greased, then the
alignment recess can cut the O-ring. Greasing the O-ring
before connecting the plug to the socket will prevent this
from happening.
2. The O-ring at the bottom of the receptacle is easily lost. It
is specially made for Impulse and has a non-standard
size. Replacements may be obtained, but the cost is
nearly five times that of a standard O-ring of similar size.
Do not lose this O-ring. If you do, contact RBR for a
replacement.
Recent loggers are equipped with IE55 connectors and the following guidelines
are provided:
• Lubricate mating surfaces with 3M Silicone Spray or equivalent. DO NOT
GREASE. Connectors must be lubricated on a regular basis.
• IE55-1200 contact surfaces must be dry prior to mating.
• Lubricate O-rings with Dow Corning #111 Valve
Lubricant or equivalent.
• Keep O-ring grooves clean and avoid cuts and nicks
in the O-ring. Replace O-rings when re-mounting
connectors.
• Avoid contact with solvents.
• Avoid sharp bends at cable entry to connector.
• Elastomers can be seriously degraded if exposed to direct sunlight or high
ozone levels for extended periods of time.

Using an RF modem

XR series loggers may be connected to an RF modem, making it possible to
program the logger remotely and to view and save data as it is collected.
The COM settings portion of the Software guide (p.32) has configuration
instructions for the RF modem. The Real-time display section (p.20) has more
details about live data collection.
