Hotkey sequences and Adder Port Direct
AdderLink IP Gold allows you to enter commands suitable for any KVM switch
in order to choose from up to 128 host systems. These switching commands can
take the form of hotkey sequences that emulate standard keypress combinations
or, for KVM switches that support the Adder Port Direct format, merely basic
port numbers.
Hotkey sequences
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)
A list of permissible keypresses and information about how to abbreviate them
are given in Appendix 8.
Notes
• The entries are not case sensitive.
• 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hotkey
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.
Examples
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
Adder Port Direct
Adder Port Direct is totally transparent communication system that allows
supporting KVM switches and remote access devices to communicate with each
other. Using the keyboard connections that link each device, Adder Port Direct
allows:
• Acontrollingdevicetoprovideaddressdetailsoftherequiredport,theuser’s
name and access rights, mouse calibration and video mode information.
• Acontrolleddevicetoconrmtheaddressandotherdetailsofthecurrentport.
Such communication simplifies both the configuration and selection of systems,
especially within a complex cascade structure. Adder Port Direct also allows the
AdderLink IP Gold Hosts option to directly control the connected KVM switches
and then apply the appropriate video capture and mouse scaling settings. Adder
Port Direct provides excellent security control to prevent users from accessing
systems for which they do not access rights (‘sideways movement’) because each
unit is fully informed of each user’s precise access rights.
Port/host addressing using Adder Port Direct
When adding new computers to the Hosts list, the option ‘Add entry for
unrecognised host’ is provided to automatically add new entries if a port is
visited that does not already have a matching host entry. This is a useful option
for simple KVM switch configurations, but should be used with care when
complex cascades of switches are being used as it may lead to more host entries
being added than are strictly necessary.
Additionally, you can specify the port number of the required system using the
same format as if controlling the KVM switch directly. Port numbers MUST be
entered within square brackets and can be specified to a maximum of four
cascaded levels.
