3 Overview
The Kramer Pico TOOLS PT-1H Hs Delay Corrector is a high performance
sync delay corrector that can be used for any graphics twisted pair cable (or
coax) application.
When sending a VGA signal from a PC to a monitor via twisted pair (or coax)
cabling, the picture information and syncs are delayed, but by different
amounts. This causes the display on the monitor to shift horizontally. The
PT-1H compensates by shifting the syncs accordingly, so that they line up
with the picture once again.
Note that the unit is transparent for the RGB signals, and corrects only the H and
V signals
Achieving the best performance means:
Positioning your PT-1H away from moisture and excessive sunlight and
dust, and avoiding interference from neighboring electrical appliances
Connecting only good quality connection cables, thus avoiding
interference, deterioration in signal quality due to poor matching, and
elevated noise levels (often associated with low quality cables)
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit1.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

5 Using the PT-1H Hs Delay Corrector
A delayed sync can be corrected by the PT-1H when using, for example, the
TP-121 and TP-122 to configure an XGA/Audio Line-to-Twisted Pair Transmitter
and Receiver system.
To connect the PT-1H via twisted pair cabling, as the example in Figure 3
illustrates, do the following:
1. On the TP-121, connect the XGA source (for example, a laptop’s graphics
card) to the XGA INPUT HD15F connector2.
2. On the TP-122, connect2 the XGA OUT HD15F connector to the XGA IN
HD15F connector on the PT-1H.
3. On the PT-1H, connect the XGA OUT HD15F connector to an acceptor (for
example, a display).
4. Connect the LINE OUTPUT RJ-45 connector on the TP-121 to the LINE IN
RJ-45 connector on the TP-122, via UTP cabling2 (with a range of more than
300ft (>100m)).
5. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity on the PT-1H and on both3 the TP-121 and the
TP-122.
6. On the PT-1H, adjust4 the DELAY level, if required.
The signal from the XGA source is transmitted via CAT5 cable, decoded and
converted at the XGA OUT HD15F connector on the TP-122. The sync delay
is corrected by the PT-1H, enabling a “lined-up” image to reach the XGA
acceptor.

2 Refer to the Kramer TP-120 and TP-121 user manual for installation information
3 If you cannot connect the power to both the TP-121 and TP-122, you can just connect the power to the TP-122
4 Use a screwdriver to carefully rotate the trimmer, adjusting the DELAY level
