1. Introduction
This manual describes the UTB-100 (Universal Transmitter Board) as well as the setup and tuning
procedures needed to put the UTB-100 and URB-100 electronics into operation. For details on the
receiver board, see the RX Tuning Guide.
1.1. Basic Description of the Transmitter Electronics
Each transmitter electronics is able to feed one LUCATRON antenna with a swept HF signal of
MHz. In order to avoid disturbances between the emitted HF signals, synchronization with other
8.2
transmitters must be guaranteed.
The standard version of the UTB-100 board allows the 82
signal to be:
−−−−
generated locally (oscillator circuit for master applications) , or alternatively.
−−−−
to be regenerated from an optically received swept HF signal of another TX (opto
receiver for slave applications).
The bi-opto version of the UTB-100 additionally allows the onboard generated (master) or receivedand-then-regenerated- (slave)-swept HF-signal to be converted and optically transmitted in order to
synchronize additional transmitters.
The two opto transmitters used in the bi-opto version allow:
−−−−
a master transmitter to synchronize two other optically slaved (and possibly repeating)
transmitters.
−−−−
an optically slaved transmitter to be used as repeater to synchronize two other optically
slaved transmitters.
By using 3 bi-opto transmitter boards (TX) (one used as synchronization master and two as
synchronization repeaters) and 4 standard TX (as synchronization slaves), clusters of up to 7 TX may
be synchronized. This way up to 7 checkout or 14 exit-gates (in a row) may be configured without
need of a master rack.
Since the optically transmitted synchronization signal may be repeated only once, a master rack still
has to be used if more than seven transmitters have to be synchronized.
Hz sinusoidal modulated 8.2 MHz HF carrier
A block diagram and layout of the UTB-100 board are shown on the next 2 pages. The board consists
of a digital part, an analog part and a power supply / filter part.
The standard version of the UTB-100 is fully equipped with the exception of the two optional opto
transmitters. It can be used as a master-TX for small installations (single or dual gates equipped with
one TX only) or as slave-TX for all larger applications.
The bi-opto version of the UTB-100 board is almost identical to the standard version. The only
difference is that the two opto transmitters (IR-LED's) are already mounted. The bi-opto TX board can
be used as a master-TX in medium installations (2 to 7 TX) or as synchronization signal repeating
slave-TX for medium to very large installations.
