| switcher or other RS‑232 controllable device. |
| If you connect an optional switcher (such as an Extron |
| MLS Series switcher) to the MLC, you must connect a ground |
| wire between the switcher and the MLC, as shown in the |
| following diagram. |
NPower the controller via an external power supply, not from an Extron switcher. The controller requires a separate 12 VDC power supply.
NCheck the power supply’s polarity before connecting it to the MLC. See the diagram below.
