Resumen del manual
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 UT250-101 allow 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 UT250-101 automatically 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 UT250-101 automatically 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 UT250-101 automatically 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. 400-0503-001 13 DESIGNER SOLUTIONS 7.2 RS-232 CONTROL The UT250-101 has many advanced remote-control capabilities accessible through standard RS-232 communication. Control may be accomplished through a computer, control system, or any device capable of RS-232 communication. 7.2.1 RS-232 INTERFACE The control commands for the UT250-101, are in a simple ASCII character format. 1. Square brackets “[ ]” are part of the command. 2. Use uppercase letters for all commands. 3. Spaces are not legal characters. Commands instruct the UT250-101 to perform specific actions or request information. Some commands do both simultaneously. A command that instructs the UT250-101 only to perform an action will generate feedback of “[ ]”. The open bracket immediately followed by a closed bracket indicates the card received a valid command. If the command requested information, the feedback generated by the UT250-101 is the acknowledgement of having received a valid command. Invalid commands generate feedback that includes “ERR” plus an error code. Example: [ERR001] Error number Commands ending in “S” will be saved into memory. Commands not ending in “S” will still be executed, but will not be restored when the system is reset or powered off, then on. 7.3 DESCRIPTION OF COMMANDS Each command consists of a function name and an optional unit ID. Unit IDs are required if 2 or more UT250-101s are to be controlled individually over the same RS-232 bus. The unit ID can be changed using the [SID] and [RSI] commands that are described later. Example: [ONU2] ON = Function U2 = Unit ID (only U2 executes ON) Unit ID “U0” does not need to be included at the end of a command string. Example: [ON]: Executed by U0 [ONU0]: Executed by U0 NOTE: Examples in this manual assume the unit ID is U0 and do NOT include the unit ID. If needed, the unit ID for any unit can be specifiedat the end of the command string as shown above. 1. [STATUS] This command displays the status of the unit. Command Format: [STATUS] Example: Send the command [STATUS] to receive feedback similar to the following: Note: Preset connections are displayed as already executed, but do not take effect until after the [SW] switch command is executed. OUT 1A -IN 1 ON OUT 1B -IN 1 ON OUT 2A -IN 1 ON OUT 2B -IN 1 ON AUDIO OUT -IN 1 ON AUTO_SWITCH -OFF If there is no card in slot 4, sending the [C4] command will not return any feedback. 400-0503-001 14 DESIGNER SOLUTIONS 2. [CLR] This command resets the UT250-101 to the last saved configuration. Command Format: [CLR] Example: Clear the UT250-101 by sending [CLR]. Any commands that were sent to the UT250-101 using the [...S] option will be recalled using this command. 3. [VER] This command displays the model number, firmware version, and unit ID. Command Format: [VER] Example: Send the command [VER], and the UT250-101 will return feedback similar to the following: [UT250-101 690-0268-001 U0] UT250-101 = the model number 690-0268-001 = the firmware version U0 = the unit ID 4. [ONmX] This command turns on one or more outputs. Command Format: [ONmX] m = Output No. (m = 1 or 2) X = Channel No. (X = A, B, or blank for both) Example: Turn on Output 1A by sending [ON1A] to the UT250-101. Outputs 1B, 2A, and 2B are unaffected. Turn on Outputs 2A and 2B by sending [O...
