Operation
1) Connection The LCT-300/400 is capable of testing cables in any one of four modes.
Local Test
mode is accomplished by connecting both
ends of the cable under test to the LCT-300/400’s OUT
and LOOPBACK IN ports. Local unit displays an ID
equal to zero.
Terminator Loopback
mode uses the terminator ID block connected at the
remote end of the cable, while the other end of the cable is connected to the
LCT-300/400’s OUT.
Remote test
mode uses two (2) LCT-300/400
units, with the cable connected between one
unit’s OUT and the other unit’s LOOPBACK
IN ports. Local unit displays an ID equal to
zero.
10BASE-2 Test
uses the supplied RJ-45 to BNC adaptors
(LCT-400 only). The adaptors may both be placed in the
LCT-400’s OUT while the other is placed on the
terminator for LOOPBACK testing.

Cable testing
: During any mode of cable testing, the first screen display will show the top line out and bottom line in of connections 1 through 8 plus G (shield) as
they are scanned. Following this screen page will be the cable identification information. If at least one wire pair is not connected, the display will read “NO
CONNECT”. A shorted cable will read “SHORT”. A question mark in the pin out indicates a short. An unknown is not in the standard known pin outs or in the
user defined memory.
User Defined Cable
: The
User Define
function allows you to describe your own custom cable pin out which will be entered into the cable identification database
and saved in the CPU memory. This custom pin out will remain available as long as a fresh battery is in the unit. Two methods are available for defining a cable.
The first method is manual entry, while the second uses an “UNKNOWN” cable as the pin out source. First the manual method. From the very top of the
LCT-
300/400
menu (just after power on is completed) select the USER DEF menu by pressing the
MODE/SEL
button (step no.1 to 2).
The MODE/SEL
button will
now move the cursor to select one of four user memory locations (step no. 3). Press
ENTER
to select the memory location that the cursor is on. The define cable
display will show (step no. 4).
