INSTALLING YOUR UT250-101 | 6 |
Step 1. Decide how the UT250-101will be controlled: using contact closures on the Output Select Controls, through computer control using the RS-232 input, using auto-switching, or all 3 methods.
If using the Output Select Controls, see Diagram 6 for wiring information.
Step 2. Locate the best position for the UT250-101, but do NOT mount it to the surface until all the cables are prepared.
Step 3. Prepare the mating cables using high-quality cables for best results and durability. Make sure the cables are long enough to allow for a service-loop and so the cables can be neatly routed beneath the table to their destinations.
Step 4. Secure the unit under the table using the screws provided with the unit.
Step 5. Make all necessary connections to the UT250-101.
Step 6. When making connections to the terminal blocks (audio out, control, RS-232, etc.), use 24-28 AWG stranded wire for best results. Also, use multi-conductor cable where possible. For example, a standard 4-conductor cable works well for the RS-232 connection.
Step 7. Use the cable clamps provided to secure the cables to the bottom of the table/desk. Do NOT bend the cables too sharply
Step 8. Attach the cable support to the UT250-101as shown in Diagram 5. This will help alleviate the strain of the cables pulling from the connectors and protect the cables from being accidentally pulled free or damaged.
Step 9. After power is applied to the UT250-101, the unit is operational.
7.1 MANUAL CONTROL
7.1.1 OUTPUT SELECT CONTROLS
The Output Select Control inputs on the front of the UT250-101allow 8 users direct control of video switching. In this method, each user typically has a control panel with 2 illuminated switches along with video and audio inputs. (See Diagram 6 for details and wiring information.)
When a user presses a control switch, the video and audio from that control panel are displayed at the output of the UT250-101. Each switch connects its corresponding input to 2 outputs, either 1A/1B, or 2A/2B. Once the connection is made, the LED for that switch turns on. If the switch’s LED is on and the switch is pressed, the output is disabled and the LED turns off. The audio output follows the last video input selected.
7.1.2 AUTO-SWITCH MODE
In Auto-Switch mode, the UT250-101automatically switches to the lowest input number with an active signal applied. For example, if there is a signal on Input 4 and a new signal is applied to Input 2, the outputs defined with the Auto-Switch command will switch to Input 2.
The Output Select Control inputs override Auto-Switch mode. When a user selects an input using an external switch, the UT250-101automatically switches to the selected input.
In Auto-Switch mode, Input 8 is designed for use as a logo input that displays when the system is not in use. If Auto-Switch mode is enabled then overridden by the Output Select Control inputs, when all active inputs are removed from Inputs 1-7, the UT250-101automatically switches to Input 8.
Auto-Switch mode must be set using the RS-232 input. See the AUTO commands in the following section for details.
