SECTION 2 - INSTALLATION
2.1 UNPACKING AND INSPECTION
The Model TMA VXI-27 has been carefully inspected and tested prior to packing. Inspect the
shipping carton immediately upon receipt for evidence of damage during transit. Save the orig-
inal packing material. If any indication of damage is found file a claim immediately with the
responsible transport service.
For repairs of a product damaged in shipment, contact the Kepco Factory Representative
nearest you or the Kepco Customer Service Department directly for further instruction.
2.2 INSTALLATION
The installation and setup procedure for the TMA VXI-27 consists of the following steps:
1. Set the VXI Address Selector (PAR. 2.2.1)
2. Select an empty slot in the C size VXI chassis and remove the slot cover plate.
3. Turn off the power if it is on and slide the TMA VXI-27 module into the chassis with the
LEDs up (or to the left in the case of a horizontal chassis). Secure TMA VXI-27 to chassis
with self-retaining screws at the top and bottom of the front panel
4. Connect the 9 pin D-type connector located on the front panel to the power modules
through the Control Bus in a daisy chain configuration using the control bus cable supplied
(see Figure 1-2). For installations that exceed the length of the control bus cable supplied,
refer to Table 1-2 for cable specifications; the maximum cable length is 300 meters (1000
feet).
5. Connect Terminator (supplied) to last IEEE 1118 control bus connector in daisy chain (see
Figure 1-2). (For Kepco MAT power supplies with 5-pin round connector, use terminator P/
N 195-0075; see Table 1-2.)
NOTE: Terminator must be used even if only one power supply is connected to the Controller
to ensure reduction of spurious noise and proper impedance matching.
6. To use the AUX. SIGNALS connector refer to PAR. 3.1.2 for a description of the available
signals and PAR. 2.3 for connector type and pin assignments.
7. Connect all power module outputs to their respective loads.
2.2.1 VXI ADDRESS SELECT
Set the VXI address selector to an unused VXI address between 1 and 254 using DIP
switches accessible through the right shield as shown in Figure 2-1. The TMA VXI-27 address
is preset to the factory default address of 6.
2.3 FRONT PANEL TERMINATIONS (SEE FIGURE 2-2.)
a. IEEE 1118 (Control Bus) connector. Connections to the control bus are made through the
IEEE 1118 connector, a 9 pin D-type female receptacle. Refer to Table 2-1 for pin assign-
ments.
