SWITCHERS PRECAUTIONS / SAFETY WARNINGS • 1 To turn off the main power, be sure to remove the cord from the power outlet. The power outlet socket should be installed as near to the equipment as possible, and should be easily accessible. • Do not pull the power cord or any cable that is attached to the MX2456RM Switcher. • If the MX2456RM Switcher is not used for an extended period, disconnect the power cord from the power outlet. 1.

SWITCHERS 4.1 FRONT PANEL CONTROLS 4.1.6 AUDIO VOLUME CONTROL MODE There are two sections on the front panel of the MX2456RM: input-select and switcher-control. The buttons within the input-select section allow for the actual switching of the source signals. The buttons within the switcher-control section allow access to the switcher setup features. This button allows the user to control the audio volume using the UP or DOWN buttons.

SWITCHERS INSTALLING YOUR MX2456RM 6 OPERATION Step 1. Make sure that the power input is set to the proper AC voltage for the country of usage. 7 7.1 CONTROL PANEL 1. When a button is pressed and released, a beeper will sound once. WARNING: An incorrect setting may result in unit damage not covered by the warranty. 2. Default video and audio inputs are selected simultaneously by pressing and releasing one of the video input buttons.
SWITCHERS 7.2 RS-232 CONTROL 6. If necessary, select the SYNC DELAY UP or DOWN button. To activate and set the SYNC DELAY mode to memory, press and hold the UP and DOWN button. LEDs that represent the selected time should light. The MX2456RM Switcher offers remote control capabilities through RS-232; the primary communication standard used by control systems and computers. 7. To activate the AUTO-SWITCH mode, press the AUTO-SWITCH button. The LED that represents the AUTO-SWITCH mode should light.
SWITCHERS Typically, a control system or computer will offer RS-232 connections on a 9-pin D connector. The RS-232 input has a 16-character buffer and the MX2456RM will not execute any commands longer than 16 characters. Any additional commands are ignored until the previous command is fully processed. After processing a valid command, a text string that includes the Unit ID and “OK” will be returned. The following are typical cable pin-out designations for RS-232 connections on a 9-pin D connector.
SWITCHERS 3. [#SW n1 n2 n3 n4 n5 n6] – Input Select The feedback returned will be as follows: This is the main command of the switcher that contains all the information needed by the switcher to activate the video and/or audio sources that are connected to the unit. [1OK] 5. [#RO] – Operation Reset The [#RO] command will reset audio and video to Input 1, Auto Switch to OFF and Beep OFF to Beep ON. However, this command will not affect audio volume, video equalization, auto-rotation, and sync-delay.
SWITCHERS 7. [#CSDn] – Sync Delay Example: This command allows time delay between switching from one video source to another by avoiding an overlap of communication problems. Sending the [0AS1] command will set the auto switch feature to the ON position to detect the incoming video signal automatically. #= n = The feedback returned will be as follows: Unit ID (# from 1-9, default is 0) Time delay interval between video sources and switching inputs 0 = Sync Delay is Off (no delay) 1 = 0.
SWITCHERS TROUBLESHOOTING GUIDE 8 We have carefully tested and found no problems in the supplied MX2456RM; however, we would like to offer suggestions for the following: Cause 2: The wrong input is selected. Solution: Verify the front panel LEDs are on as expected. If Break-Away mode is on, it is possible to have an audio source that does not match the video source. If no sound is present, see Cause 3. 8.1 NO POWER Cause: The line voltage is wrong or off. Cause 3: Cable connections are incorrect.
SWITCHERS 8.5 SOUND LEVEL IS LOW Cause 1 ALTINEX POLICIES Input volume is low. 9.1 LIMITED WARRANTY/RETURN POLICIES Solution 1: Turn up the source volume. If the sound level is still low, see Solution 2. Please see the ALTINEX website at www.altinex.com for details on warranty and return policies. Solution 2: Turn up the destination amplifier volume. If the sound level is still low, see Cause 2. 9.2 CONTACT INFORMATION ALTINEX, Inc. Cause 2 Poor signal transmission.
