Instruction manual

Hole − See hole collection. Because of the way
current and older datalogger data are collected
simultaneously, there can be sequences of
older data that are available from the datalogger
but have not yet been collected. DBSelect
tracks and optionally collects these holes
Hole Collection − See Hole. Process used to
collect a specific range of data from a
datalogger. Usually used to collect data to fill
RTM strip charts or to collect data not collected
with Data Advise.
Keyboard display − A hand-held display and
keyboard used to access CR10T datalogger
programming, and star mode (* mode)
information directly. Model CR10KD.
Kick − When a transaction fails, it is usually
retried until it succeeds. Retries are based on
intervals specified by user. To “kick” a
transaction is to force an immediate retry.
Link − Communication route between to
devices, e.g., phone link between two phone
modems.
MD9 − A mutidrop modem where several
CR10T dataloggers (with MD9 modems) are
attached to a single coaxial cable along with a
MD9 at the computer. DlsMgr “dials” the base
MD9 to access the remote dataloggers. The
MD9 are individually addressed.
Named Pipe − See Acknowledged Named Pipe
and Unacknowledged Named Pipe. Method
provided by OS/2 for two programs or process
to exchanged data. Used with RTMS to make
datalogger data available to user-written
programs. DBSelect provides an
Acknowledged Named Pipe and an
Unacknowledged Named Pipe.
Net Description − Description of dataloggers
and communications devices that form the
datalogger network. Entered as with NetAdmin
and used by DlsMgr to communicate with the
various dataloggers.
NetAdmin − Network Administration program,
Used to: monitor network communication and
health, edit network descriptions, set/check
clocks, download datalogger programs, interact
directly with dataloggers, and test RF links.
Network Health − Pertaining to DlsMgr ability
to collect data and communicate with the
datalogger in the datalogger network. Network
Health indicators are displayed on the main
NetAdmin screen.
Node − Part of the description of a datalogger
network (Net Description). Represents a device
that DlsMgr will directly communicate with or
dial. Nodes are organized as a hierarchy with
all nodes accessed by the same device (parent
node) grouped as children nodes. A node can
be both a parent and child node.
Packet − A unit of information sent between two
devices that are communicating, can contain
data, messages, programming, etc. Usually
contains addressing and routing information.
Path − A list of modems or devices used to
communicate with a remote site datalogger.
Pipe − See Named Pipe.
Polling − Process where a datalogger or other
communication device is periodically checked
for any packets it needs to send. DlsMgr polls
dataloggers for most communication links.
With radio (RF) the base RF232T or repeaters
can poll datalogger sites.
Polling Interval − See Poll. The user-
specified interval that determines when to poll a
given device.
RAD Modems − Short haul modems for
communicating with a CR10T datalogger over
twisted pair wire connection. RAD is the
trademark name for the modems manufactured
by RAD Data Communictions, Inc.
Real-Time Monitoring Software − Collection
of OS/2-based software for automated data
acquisition, monitoring, and control of CR10T
datalogger networks.
Remote Keyboard − A mode provided by
NetAdmin that emulates the functionality
available with a Keyboard display.
Remote site − Usually refers to the site where a
datalogger is located at other end of
communication link. Also can refer to site
where a radio (RF) repeater is located.
