Set Keyboard Typematic - Black Box ServSwitch Jr. SW621A-R2 Manual

SERVSWITCH™ JR.
• you don't know which mode the CPU uses or the port is set for, but the
keyboard's behavior makes you suspect that the port's setting is wrong.
To set the keyboard mode of the currently selected port on a ServSwitch Jr., press
and release the left Control key, type [M], and press the numeral key of the mode
number ([1], [2], or [3]). After you enter this command, enter the Keep Settings
command to save the mode setting in NVRAM, so that the new setting becomes the
default value (preserved during power-down and reloaded at power-up).
If most or all of the CPUs you'll be connecting to your ServSwitch Jr. system use a
keyboard mode other than 2, you might want to change the defaults of their Switch
ports at installation time. This is because when power outages occur, the Switch
ports will return to their default keyboard mode when the power comes back on.

Most keyboards have an internal seven-bit "typematic" setting, which governs the
way the keyboard responds when you hold a key down to force it to repeat. The five
"low" bits of this setting represent the rate at which the key repeats; the two "high"
bits represent the delay after you begin holding down the key before it begins to
repeat. Sometimes a keyboard's typematic setting isn't suitable for a given operator
or for a given application. To change the typematic setting of your station's shared
keyboard, issue the Set Keyboard Typematic command: Press and release the left
Control key, type [A] followed by the desired "typematic value," and press
[ENTER]. The "typematic value" is the decimal equivalent of the binary seven-bit
typematic setting: While the typematic setting = delay bits + rate bits, the typematic
value = decimal delay value + decimal rate value (see Table 4-4 below and Table 4-5
on the next page). For example, to set your shared keyboard to register a key
16 times per second after the key has been held down for half a second (typematic
value = 7 + 32 = 39), type [Ctrl] [A] [3] [9] [ENTER]. Enter the Keep Settings
command after you enter this command.
