Screw terminal board
The UAIS Transponder has a build in screw terminal board which makes it very easy during
installation to connect cables to the power sources, to sensors, to the VDU and to other display
units through the Main and AUX ports.
Refer to the wiring diagram, attached as an appendix, for details of connections to the screw
terminal board.
Fuse values
The main system fuse (10 amp) is located on the screw terminal board. A separate fuse (1 amp)
on the screw terminal board protects the VDU. Both power supplies are reverse polarity
protected.
Fuse description Fuse value Part No.
Main system fuse 10.0 Amp 99-077
VDU system fuse 1.0 Amp 99-076
Signal line termination
Signal lines may need termination by a resistor across the inputs. These resistors are
incorporated on the screw terminal board and can be switched in or out by the switches S2, S4,
S5, S6, S7, S8. The switches are identified on the Screw Terminal Board diagram on Page 6.
Note:
1. Each switch is a double unit
2. S2 and S5 each control two signals individually
3. S4, S6, S7 and S8 – both switches should be moved together
4. S3 has been deleted
