10 SER VSWITCH™ JR. MP 2. Introduction Thank you for choosing a ServSwitch Jr.™ MP. Designed with your needs in mind, your new Switch will simplify your job by helping you organize your multiple- computer application. Because the ServSwitch Jr. MP lets you use a single keyboard, monitor, and mouse to access one or two IBM ® PC compatible compu[...]

11 CHAPTER 2: Introduction • If your application is not very demanding, the Switch can operate using only a portion of the attached computers’ keyboard power. For higher-level applications, an external power supply is included. • You can select the desired CPU from your keyboard or from the Switch’s front panel. • Front-panel LEDs show wh[...]

12 SER VSWITCH™ JR. MP 2.3 The Front Panel The ServSwitch Jr. MP’s front panel features three or five membrane switches and the same number of LED indicators. To familiarize yourself with these controls and indicators, refer to Figure 2-1 and the descriptions that follow. Figure 2-1. The front panel of a 4-port Ser vSwitch Jr . MP (SW628A-R2). [...]

13 CHAPTER 2: Introduction 2.4 The Rear Panel All cable connections are made at the ServSwitch Jr. MP’s rear panel, as illustrated (in Figure 2-2) and described below. Figure 2-2. The rear panel of a 4-port Ser vSwitch Jr . MP (SW628A-R2). Panel Label Connector Description Ports 1, 2, 3, 4* DB25 F Connect the sharing computers to these ports with[...]

14 SER VSWITCH™ JR. MP 2.5 Cable Requirements Many switches of this type have what seems like ten million connectors on their rear panels: one for each CPU’s video cable, one for each keyboard cable, and a third for each mouse cable. The potential for tangling or mismatching cables is high. By contrast, you can connect the ServSwitch Jr. MP to [...]

15 CHAPTER 3: Installation 3. Installation 3.1 Rackmounting (Optional) If you want to mount the ServSwitch Jr. MP in a 19", 23", or 24" rack, you will need a ServSwitch Rackmounting Kit (our product code RMK19M, RMK23M, or RMK24M respectively). The Switch is pre-drilled to accept the Kit’s rackmounting screws. See Appendix C for mo[...]

16 SER VSWITCH™ JR. MP 3.3 Connecting the CPUs CPU Cables run from the ServSwitch Jr. MP to the keyboard port, video-output port, and (on PC CPUs) mouse port of each CPU you want to directly attach to it. Different types of this cable fit the connectors on different computers (see Appendix B ). This cable also comes in the different lengths suppo[...]

17 CHAPTER 3: Installation CAUTION! Do not attach docking stations for older models of the ThinkPad ® or other portable computers to the ServSwitch Jr. MP. The Switch currently supports only “stream mode” (continuous) mouse data, but older ThinkPad models have to see “prompt mode” (burst-on-request) mouse data. Some newer docking stations [...]

18 SER VSWITCH™ JR. MP 4. Operation The first part of this chapter, Section 4.1 , gives you some guidelines that you should follow to make sure your ServSwitch Jr. MP works properly with your equipment. Section 4.2 summarizes the ServSwitch Jr. MP’s keyboard commands, and Section 4.3 describes these commands in detail. NOTES To start any ServSw[...]

19 CHAPTER 4: Operation might not work properly with keyboards that have proprietary keys or connectors or use proprietary keyboard-scan modes. Standard PC keyboards have between 101 and 105 keys. In order to reproduce all of the functions of the Apple keyboard, which has 105 keys (not all the same as those on the 105-key PC keyboard), we have “m[...]

20 SER VSWITCH™ JR. MP 4.1.3 M ONITOR NOTE No keyboard/video switch can provide perfect video. You will see at least a little fuzziness on your monitor no matter how close to ideal your ServSwitch Jr. MP system is. While PC-type CPUs and VGA monitors normally use two separate leads to send/receive sync signals (one lead for horizontal sync and on[...]

21 CHAPTER 4: Operation The ServSwitch Jr. will support SVGA (Super VGA) video, but with original Serv cables the video quality for SVGA and Mac video will decrease markedly at higher resolutions and distances. Table 4-1 illustrates this. The distances in the table are total cable lengths measured from the CPU to the monitor. T able 4-1. Video Qual[...]

22 SER VSWITCH™ JR. MP By contrast, coaxial cables (required for XGA applications, and recommended for most other applications) do much better at maintaining video quality, as shown in Table 4-2. (For the meaning of quality numbers 3 , 2 , and 1 , see the bottom of the previous page.) As before, the distances in the table are total cable lengths [...]

23 CHAPTER 4: Operation 4.2 Keyboard-Command Summary Table 4-3 on this page and the next page summarizes the commands that can be sent to the ServSwitch Jr. MP. To enter any command at the shared keyboard, first press and release the left Control Key ([CTRL]). This cues the Switch to look for commands from the keyboard. Then enter the command follo[...]

[CTRL] E x [ENTER] ( x = 0, 1, or 2) Set Apple Emulat[...]

25 CHAPTER 4: Operation 4.3 The Commands in Detail 4.3.1 S ELECTING A P ORT FROM THE S HARED K EYBOARD 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 t[...]

26 SER VSWITCH™ JR. MP 4.3.5 S END N ULL B YTE (PC CPU SW I T H PS/2 M OUSE P ORTS O NLY ) PS/2 type mice send control data to CPUs in three-byte increments. Sometimes, because of electronic transients, unusual power-up effects, or plugging and unplugging of cables from live equipment, the currently selected PC type CPU in a ServSwitch Jr. MP sys[...]

27 CHAPTER 4: Operation 4.3.8 S ET M AXIMUM P ORTS (SW628A-R2 O NLY ) Use this command to tell a 4-port ServSwitch Jr. MP the total number of CPU ports to which computers are or will be connected. This allows the scan function to cycle correctly if you have computers attached to only two or three of the Switch’s CPU ports. To issue the Set Maximu[...]

28 SER VSWITCH™ 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 [...]

29 CHAPTER 4: Operation 4.3.11 S ET K EYBOARD T YPEMATIC Most IBM PC type 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[...]

31 CHAPTER 4: Operation 4.3.12 S ET A PPLE E MULATION Your shared keyboard must be an IBM PC type. In order for you to be able to reproduce all of the keyboard-driven functions of your Mac CPUs, the ServSwitch Jr. MP has to “map” some of the important keys on the Mac keyboard to keys on the PC keyboard that are either duplicates of other keys o[...]

32 SER VSWITCH™ JR. MP [E][1]: Swapped Mapping (104/105-Key Keyboard, Mac Users) For those of you who are used to the placement of the command and option keys on the Apple keyboard and would like to preserve that key arrangement on the Windows keyboard, you can enter the [E][1] command to switch to a mapping that swaps the command- and option-key[...]

33 CHAPTER 4: Operation 4.3.13 S ET M OUSE T RANSLATION (PC CPU SW I T H S ERIAL M OUSE P ORTS O NLY ) If each IBM PC CPU attached to your ServSwitch Jr. MP has a PS/2 mouse port, you can plug a PS/2 mouse into the Switch and control them both without having to reconfigure the system at all. However, if an attached PC CPU has an RS-232 serial mouse[...]

34 SER VSWITCH™ JR. MP 5. T roubleshooting The first two sections of this chapter discuss some of the problems that can arise in a ServSwitch Jr. MP system and suggest possible causes and solutions.
