Black Box SW627A-R2 The Commands in Detail, Operation, Selecting A Port From The Shared Keyboard

CHAPTER 4: Operation

4.3 The Commands in Detail

4.3.1SELECTING A PORT FROM THE SHARED KEYBOARD

To select a port from your keyboard, press and release your keyboard’s left Control Key ([CTRL]), then press the number key corresponding to the number of your desired port ([1], [2], [3], or [4]). The ServSwitch Jr. MP will immediately switch to that port. You can always, of course, select any port by pressing its numbered button on the Switch’s front panel.

4.3.2SWITCHING TO THE NEXT OR PREVIOUS PORT

From the keyboard you can go forward or backward through the ServSwitch Jr. MP’s ports by selecting either the next or the previous port respectively. To switch to the next port, press and release the left Control Key ([CTRL]), then press the plus key (the key at the top of the keyboard marked with [=] and [+]). To switch to the previous port, press and release [CTRL], then press the minus key (the key at the top of the keyboard marked with [–] and [_]). The command is not case- sensitive. Do not use the [+] and [–] keys on the keyboard’s numeric pad; the Switch doesn’t recognize these.

4.3.3SCAN MODE

To enable scanning (switching from CPU to CPU in a continuous rotation) from the keyboard, press and release the left Control Key ([CTRL]), then press [S]. The ServSwitch Jr. MP will begin scanning sequentially from its currently selected port through the higher-numbered ports, then begin again at CPU Port 1. As it scans, it delays 1 to 15 seconds at each port. (This “Scan-Delay Time” is user-selectable; see Section 4.3.9.) To stop scanning, press and release [CTRL], then press [X]. You can also disable scanning by entering a Select Port command. (ServSwitch Jr. MP letter commands are not case-sensitive: You can enter upper- or lower-case letters.)

4.3.4RESET

This command, along with the commands described in the next two sections, comes in handy when certain problems arise. It will reset or refresh your shared equipment. Issue it if (a) your shared keyboard gets stuck or begins behaving oddly, (b) you need to send mouse data to a CPU that hasn’t enabled the mouse (this can happen if you boot up the CPU while the ServSwitch Jr. MP is off or disconnected), or (c) while using a PS/2 type mouse, you unplug it, then plug it back in. To issue the Reset command, press and release the left Control Key, then type [R]. (If you’re using a PS/2 type mouse, don’t issue this command to a PC type CPU that doesn’t have a mouse driver loaded. Many PCs will crash if you send them unexpected mouse data.)
