8X1 DVI KVM DL SWITCHER REMOTE INSTALLATION To use the RMT-8IR remote, remove the battery cover on the back of the remote to reveal the battery compartment. Insert the included battery into the open battery slot. The positive (+) side should be facing up. Ensure that both DIP (Dual Inline Package) switches are in the OFF position. Replace the battery cover. The remote ships with 2 batteries. One battery is needed for operation and the other battery is complimentary.
PAGE 12
RMT-8IR REMOTE AND 8X1 KVM SWITCHER CONFIGURATION How to Resolve IR Code Conflicts In the event that IR commands from other remote controls conflict with the supplied RMT-8IR remote control, changing the remote channel will alleviate this issue. The RMT-8IR remote control and the 8x1 DVI KVM DL Switcher both have banks of DIP (Dual Inline Package) Switches for configuring the remote channel that both units use to communicate. These settings must exactly match each other for proper operation.

EDID MODES EDID. What is it,, and what is it used for? Under normal circumstances, a computer source device (digital or analog) will require information about a connected device/display to assess what resolutions and features (capabilities) are possible. The source device can then cater its output to create resolutions and/or features that are compatible with the attached device/display. This capability information is called EDID (Extended Display Identification Data).
PAGE 14
EDID MODES EDID Modes The diagram below illustrates the 4 DIP switch bank. The 8 DIP switch bank functions are outlined later on this page. DIP SWITCH Function 1 IR Channel 2 IR Channel 3 EDID Mode 4 EDID Lock Mode 1 2 3 4 Use DIP switch 3 to set the desired EDID mode. 1. • LOCAL EDID Mode (Switch 3=OFF) DEFAULT EDID that is stored in the LOCAL memory location is passed to all inputs.
PAGE 15
DL (DUAL LINK) ONLY MODES DL ((Dual Link)) Only y Modes The 8 DIP switch bank, located on the underside of the 8x1 DVI KVM DL Switcher cab be used to set each individual input to work in a Dual Link Only mode. These modes should only be enabled if issues occur when using Dual Link sources and displays in the default mode.
PAGE 16
RS-232 SERIAL COMMUNICATION What features are available via the RS-232 serial communications port? p The 8x1 DVI KVM DL Switcher can accept commands through the RS-232 serial communications port located on the rear panel. The current RS-232 control features are: • Switching/routing of inputs to outputs without the RMT-8IR remote control. • Switch EDID modes without operating the DIP switches on the underside of the unit. • Managing the EDID bank and EDID that is loaded into the LOCAL EDID.

RS-232 SERIAL CONTROL COMMANDS RS-232 Features RS-232 remote functions are used to control of this product’s features. Features include input to output routing, EDID storage, EDID management, etc. Functions Syntax y The syntax for each function is always the same: #Character as the start flag → Function name → Space ( _ ) as function name end flag → Parameter 1 → Space → Parameter n → Carriage Return ( \r ) → Sample: #FunctionName_param1_param2_param3_param4...\r Syntax is NOT case sensitive.
