Most of Adders VNC remote access products, including the IPEPS-PLUS, ALD-IPEPS, and AL-IPEPS have the ability to control a KVM Switch if connected to their console port using a macro (hotkey sequence). The macro can be configured to send a sequence of keyboard presses to instruct the KVM switch to change the port that it is showing.
Almost any combination of keypresses can be emulated using the following notations:
+ means press down the key that follows;
- means release the key that follows
+- means press and then release the key that follows
* means add a delay. The standard delay period is 250ms, however, if a number immediately follows the asterisk, this will define an alternate delay period (in milliseconds)
- The entries are not case sensitive.
- All characters can be entered using their ASCII codes, from 32 to 126 (i.e. A,B,C, …1,2,3 etc.) with the exception of the special characters above.
- It is not necessary to specify all keys to be released at the end because they are all released automatically after the last code.
- A number of KVM switches from alternative manufacturers use hotkey sequences that begin with a press/release of either the Scroll Lock or Ctrl keys. These often require a delay between the initial key press and the channel number to allow the switch to respond. A 500ms delay is usually sufficient

Hot key macro sequences can be up to 256 characters long. All keys are assumed to be released at the end of a line, however, you can also determine that a key is pressed and released within a sequence. Any of the following three examples will send a command that emulates and a press and release of the Scroll Lock key:
Press and release scroll twice, press 1 then enter then release all keys (equivalent definition is +SCROLL-SCROLL+SCROLL-SCROLL+1+ENTER-1-ENTER)
To reduce the length of the key definitions, any unique abbreviation for a key can be used. For example: “scroll”, “scr” and even “sc” all provide an identifiable match for“ScrollLock” whereas “en” could not be used because it might mean “Enter” or “End” (“ent” would be suitable for “Enter”).
Note: Hotkey sequences and abbreviations are not case sensitive.
- To send the command Ctrl + Alt 4 you should use the following: +Ctrl+Alt+4.
- To send the command Ctrl + Alt 12 you should use the following: +Ctrl+ALT+–1+2 (the ‘+–1’ entry causes the 1 key to be pressed and released before the 2 key is pressed).
- To send the command Scroll lock 1 + Enter (with a 500ms delay) you should use the following: +–Scr*500+1+Ent
- Log in using a VNC Viewer as an Admin to the unit.
- Click on the Config button in the top right-hand corner to open the Configuration menu.
- Click on the Host Configuration option.
- You will see a list of hosts, you can configure up to 256.
- Double click on an empty host slot to edit it, for example, slot 1.
- Enter the name of the host.
- Depending on the product, you will see a KVM Switch Macro field and optionally a Hotkey Host Numberas well. In this example both are present.
- The following example assumes that the hotkey combination used by the KVM Switch to change its port is Ctrl + Alt. This is entered into the KVM Switch field.
- The port number on the switch that is to be selected is 1. This is entered into the Hotkey Host Number field.
- Note: If only the KVM Switch Macro field is available then you would enter the complete hotkey sequence, e.g. +Ctrl+Alt+1
- The Power On, Power Off and Reboot options are not available on all the products. If they exist then leave them blank.
- Press Save and then Save again to return to the main menu.
- Click on Return to Host to exit the configuration menu.
- You will now notice that there is a Hosts button, and when pressed reveals a list of available hosts that have been configured, in this example, Computer 1.
- When you chose the host from the list, the unit will automatically send the key sequence to the attached KVM Switch to change port.
