3DESCRIPTION
This publication provides instructions for installing the LTC 8714 Series and LTC 8715 Series Keyboard Port Expanders in an Allegiant® Series matrix switcher/controller system.
A single LTC 8714 Series unit can be used to interface up to eight Allegiant Series keyboards with an Allegiant system. A single LTC 8715 Series unit is used to interface up to four (4) LTC 8714 Series expanders in a system. Multiple LTC 8715 Series expanders can be used along with multiple LTC 8714 Series expanders to provide up to 64 keyboards in a system. The actual number of units that can be used in a system depends upon the model of the Allegiant system. The table below lists the various Allegiant models and the maximum number of keyboard expander units and Allegiant Series keyboards that can be connected in a system.
Allegiant System Capacities
Allegiant | Max Number | Max Number | Max Number |
Series | of Keyboards | of LTC 8714 | of LTC 8715 |
Model | in System | Supported | Supported |
LTC 8600 | 16 | 1 | 0 |
LTC 8800 | 32 | 3 | 1 |
LTC 8900 | 64 | 7 | 3 |
NOTE: The above table assumes 8 system keyboards are connected directly into the Allegiant CPU bay keyboard ports.
For each Allegiant Series keyboard used in an "expanded configuration," one LTC 8557 Series Keyboard Extension Kit (not included) is required.
Each keyboard port expander is supplied with a single interface cable. This cable is used to connect the port expander to either the Allegiant CPU bay or to another port expander. The LTC 8557 Series Kit is then used to connect the expanded keyboards to the LTC 8714 Series Port Expander(s). See Typical Application Diagrams found at the end of this manual.
