4.5.1Expanding up to Eight Keyboards Using the LTC 8714 Series Keyboard Port Expander

1.Make sure power is turned OFF on the Allegiant Series main bay and the LTC 8714 Series Keyboard Port Expander. Make sure that the external power supply used to power the Allegiant Series keyboards is not connected to a wall outlet.

2.For each keyboard used with the LTC 8714 Series, one LTC 8557 kit is required. The LTC 8557 kit consists of two junction boxes, a power supply, a barrel plug cord, and a

3 meter (10 ft) keyboard cable.

3.Connect the 3m (10ft) cable supplied with the keyboard between the keyboard and the remote junction box.

4.Up to 1.5km (5000ft) of customer supplied 0.5mm2 (24AWG) shielded twisted pair (Belden 9841 or equivalent) may be run between the two junction boxes. Connection to the junction boxes are made to three of the four screw terminals as follows. Note reversal to data connections.

5.Connect the 3m (10ft) cable supplied

with the LTC 8557 kit between the junction box and the PORT connector on the LTC 8714 Keyboard port expander. Connect the power supply to the junction box at the remote keyboard site. Verify that the junction box power LED indicator lights. Also verify that the keyboard LEDs are flashing.

6.Similarly, repeat Step 5 for each Allegiant Series keyboard.

7.Using the cable supplied with the LTC 8714 Series Keyboard Port Expander, connect one end of the cable to the connector marked SYSTEM on the LTC 8714 Series unit. Connect the other end of the cable to the connector marked COMM2 on the Allegiant Series system (see FIGURE 9).

4.5.2Expanding Beyond Eight Keyboards Using the LTC 8714 Series Keyboard Port Expanders with the LTC 8715 Series Expander

In order to expand beyond eight keyboards, the use of an LTC 8715 Series unit in conjunction with an LTC 8714 Series unit is required. Using multiple LTC 8715 units, the remote keyboards can be expanded to 120. Note that the maximum number of keyboards may be limited by the Allegiant system. See FIGURE 10.

1.Follow Steps 1 through 7 in the previous section for connecting up to eight keyboards using the LTC 8714 Series unit.

2.Select the appropriate group number on the LTC 8714 Series unit via dip switch S402, switches 2 through 5. The group number must be unique and must not conflict with other LTC 8714 units or the local keyboards (i.e., keyboards connected directly to the ports located on the main CPU bay) in the Allegiant system.

3.Using the cables supplied with the LTC 8714, connect the SYSTEM port on the LTC 8714 to any one of the four PORTS on the LTC 8715 unit. Repeat steps 1 and 2 for all LTC 8714 Series units.

4.Using the cable supplied with the LTC 8715 unit, connect the SYSTEM port on the LTC 8715 Series unit to the COMM2 port on the Allegiant Series main bay. In this configuration, up to

32 remote keyboards can be connected using four LTC 8714 units and one LTC 8715 unit. To expand beyond 32 remote keyboards, another tier of LTC 8715 units may be used (see FIGURE 11).
