Instruction manual

GLOSSARY
Acknowledged Named Pipe
See Named
Pipe. Exchange of data through a named pipe
where the program or process (client) receiving
data must acknowledge each record of data it
receives.
Advise
See Data Advise
Baling
When DBSelect stores data in ASCII
files, it periodically makes data files available for
the user or user programs. This process is
known as baling and happens on a user
specified interval.
Baud rate
Communication speed between
two serial devices. Baud rates must match for
successful communication.
Block Mode Protocol
Protocol used by
DlsMgr to communicate with CR10T
dataloggers and RF95T RF modems.
BMP
- See Block Mode Protocol.
Broadcast
Part of the radio (RF) technique of
polling remote radio modem dataloggers sites.
A single modem sends a message (broadcast)
that all affected remotes hear and respond to.
Carrier
An electrical signal used to convey
data or other information. For example, radio
and phone modems use carrier signals. Phone
modems attempt to detect carrier when the call
is placed. The red LED on the RF95T lights
when the modem detects carrier.
Chars. RX
Number of characters (bytes)
received by the computer. Part of NetAdmin
network health display.
Chars. TX
Number of characters (bytes)
transmitted by the computer. Part of NetAdmin
network health display.
Child node
See node. A node that is
accessed through another device (parent node).
For example a remote radio (RF) site is
accessed through the base RF232T. All nodes
are children nodes of the PC.
Coaxial cable
Special type of cable with two
conductors (center conductor and outer shield
conductor). Classified by size, impedance, and
loss characteristics. Used to connect MD9
modems and to connect radios to antennas.
COM Port
RS-232 Serial port, i.e., COM1,
COM2, etc.
CR10T
Campbell Scientific datalogger
supported by RTMS, used to make
measurements at remote sites.
Data Advise
List of data to be collected,
usually from a datalogger. Sent to “advise”
datalogger of what data is needed. Based on
dataloggers Table Definitions.
Data Advise Notification
Packet of data sent
by datalogger based on the Data Advise it
received.
DBSelect
RTMS program for data collection,
storage, and routing including named pipes, and
ASCII files.
DC112
1200 Baud telephone modem for use
with a CR10T datalogger. Powered by the
CR10T datalogger.
DLD file
See EDLOG. CR10T datalogger
programs are usually developed on the
computer and then sent to the datalogger.
These datalogger programs have a .DLD
extension.
DlsMgr
Datalogger Service ManaGeR.
Manages all communication with datalogger
network. Part of the RTMS programs.
Extract
Utility program to extract ranges, sort,
check, and merge ASCII data files created with
DBSelect.
Fault
Message relating to network activity
where repeated problems or errors have
occurred. Repeated faults usually indicate a
failure of some kind.
Health
See Network Health.
