SERVSWITCH™ JR. MP

The ServSwitch Jr. MP can’t detect the CPU’s keyboard mode if the CPU doesn’t send “mode commands” (most CPUs that use mode 2 fall into this category) or if the CPU is already ON when you connect it to the Switch (it shouldn’t be). In these situations, the Switch tries to use the keyboard-mode setting stored in its nonvolatile memory for that port. The factory-default is mode 2 for all ports. Send the Set Keyboard Mode command to change the keyboard mode for a port if:

•the CPU on that port uses mode 1 or 3,

•it uses mode 2, but the default setting of the port you want to connect it to has been changed, or

•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. MP, 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. MP 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.
