There are a few optional tasks. If this is a re-installation, you can select
“Reset logger settings to default”. You have the option of adding desktop
icon.
To record automatically after login, check ‘Start Logging Automatically”.
If a machine is left unattended, this ensures uninterrupted operation in
the event of a power failure and subsequent reboot. The logger service
watchdog will automatically restart the logger if it is closed for any
reason. You can also disable automatic disk cleaning (file deletion) here.

The connector itself is sometimes called an “AMP”, “CHAMP”, "blue
ribbon", or "gray phone" connector. RJ-21 connectors are polarized
(male and female) to prevent an installer from accidentally connecting an
internal extension to outside lines (or vice versa). Although the keying
is designed to prevent inverted installation, it is possible to force a plastic
connector on in reverse.
Pins 1 (ring) and 26 (tip) are considered position 1. Pins 2 (ring) and 27
(tip) are position 2 on thru twenty five pairs. Typically, only 24 pairs are
used (48 wires). Your 16 channel logger uses only the first 16 pairs (32
wires). The last pair on pins 25 and 50 (slate-violet and violet-slate
color) should be left as a spare pair. The spare pair keeps you from
having to run a whole new cable if a single pair fails elsewhere. DLI
Loggers use this pair as an earth ground connection. The logger can be
directly connected to most RJ-21x jacks via an Amphenol cable.
RJ-21 Color Code
RJ-21 cables follow the color code standard
used in all telecom wiring: Line 1 is the blue &
white pair, Line 2 is orange & white pair, etc. as
shown.
The logger pinout complies with this telecom
standard, but
pins 17-24 and pins 42-49 (lines 17
to 24) are not connected.
The 25
th
pair provides an earth ground
connection.
When mounted correctly, a KT-66 block will have
line 1 on the uppermost pair, and line 25 on the
bottom of the block.
