1.4 TMA VXI-27 INTERCONNECTIONS
A shielded two (2) wire twisted-pair cable equipped with a 9 pin D-type, male, plug-in connector
(supplied) is used to connect the TMA VXI-27 with the power modules. Input power and input/
output signals are provided through the VXI backplane (see Figure 1-2).
An opto-isolated, active high or non-isolated, active low, emergency shutdown input is provided
on the 15 pin D-type female connector located on the front pane (see PAR. 3.1.2.1)l. On the
same connector 2 additional lines provide a normally open contact indicating the proper func-
tioning of the internal microsystem (Discrete Fault line). If either a serious malfunction or a cata-
strophic error occurs, the contacts will close (see PAR. 3.1.2.2)
In configurations where power modules are daisy chained on the IEEE 1118 control bus (see
Figure 1-2), the last power module control bus outlet (in the daisy chain) must be terminated
with the IEEE Control Bus Terminator supplied with the controller to reduce spurious noise and
provide proper impedance matching. The terminator supplied is a 9-pin, D-type connector; for
Kepco MAT Power Supplies with a round 5 pin connector use the 5 pin terminator listed in Table
1-2.
