DXE-TVSU-1A - Time Variable Sequencer Unit
The DX Engineering TVSU-1A Time Variable Sequencer Unit is a microprocessor-based transmit / receive control-
signal delay unit. It provides 0-30 ms of delay, programmable in 2 ms increments, to as many as five outputs tied to the
CW keying or push-to-talk (PTT) lines.
By controlling the receive-to-transmit (and back) timing of linear amplifiers,
preamplifiers, and other sensitive equipment, damage caused by improper
switching can be eliminated.
This sequencer improves CW performance by eliminating annoying leading
edge chopping or truncating of Morse characters. This is especially important
in contests or pileups where sending accuracy is critical.
The TVSU-1A can also control external devices such as preamps, active antennas, or external relays that need to have
power removed during transmit. Separate power-in and power-out jacks on the front panel are used to control external
power in this type of application. Two 2.1 mm power plugs and two 3.5 mm stereo plugs are provided.
Benefits

Control timing of PTT turn-on, hang delay of PTT, amplifier hang delay, external antenna relay hang delay and
turn-on delay of auxiliary output

Dip switch settable delays of 0-30 milliseconds in 2 millisecond steps

Side tone generator that follows input of keyer or hand key not transmitter

Side tone pitch can be programmed from 300 to 1000 Hz in 50 Hz steps, front panel headphone jack with
adjustable volume

Supports CW full break in

Can control external power to our Active Receive Antennas and permit operation in closer proximity to
transmit antennas
DXE-DCPC-24 DC Power Cable, 2.1 mm plug both ends
The DXE-DCPC-24 is a 24 inch red and black stripe power cable that features TWO 2.1 mm DC power connectors
known as "barrel", "concentric" or "tip" connectors, one at each end. This unusual patch cable may be used for
interconnecting devices, one of which offers a power output 2.1 mm jack, and the other requiring a nominal DC voltage
input to a 2.1 mm jack.
Length: 24 inches (61 cm) from connector to connector
Connectors: 2.1 mm power barrel plugs (aka concentric or pin plugs)
Wire: Red and Black stripe zip cord (small)
Rating: Nominal 2 A @ 13.8 Vdc
This special cable is used in applications where DC power is supplied from one device to another.
The
DXE-DCPC-24 is specifically used in a DX Engineering receiving antenna phasing system between the "PRE-
AMP POWER OUT" port on the DXE-TVSU-1A Time Variable Sequence Unit, and the "ANT PWR" power input on
the DXE-NCC-1 Receive Antenna Phasing Controller.
