CHAPTER 2: Introduction 2. Introduction 2.1 Overview The purpose of the ServSwitch™ Brand Fiber KVM Extender is to greatly extend the distance between a Sun® or IBM® PC compatible computer CPU and the keyboard, mouse, monitor, and serial or parallel peripheral that the computer operator will be using, especially in electrically noisy environments.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 2.2 The Complete Package Before you do anything else with it, verify that you received everything you should have with your ServSwitch Brand Fiber KVM Extender. These components come with both models of the Extender: • The Extender’s Local Module. • The Extender’s Remote Module. • (2) power supplies, one for each Module. • (2) power cords, one for each power supply (equivalent to our product code EPWR08). • (1) set of eight adhesive feet. • This manual.
CHAPTER 3: Configuring the ACS235A 3. Configuring the ACS235A This chapter describes how to configure the PC model of the ServSwitch™ Brand Fiber KVM Extender (ACS235A). If your Extender is the Sun model (ACS236A), see Chapter 4. 3.1 Configuring for RGB Video In normal configuration at delivery time, the Extender units are configured to carry video from a VGA source to a VGA monitor.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS the JP1, JP2, and JP3 locations to deactivate the decoupling diodes (so that the Remote Module leaves the sync signals on the color signals), and remove the jumpers at JP9 and JP12 to disable VSYNC and force the sync polarity signals negative (see Sections 3.3.1, 3.3.3, and 3.3.4).
CHAPTER 3: Configuring the ACS235A Table 3-1. Jumper Settings For all of these applications, to use AGC you must leave JP3 in the Local Module installed and keep the JP8 jumpers in the Remote Module on the left-hand posts. To operate without AGC, remove JP3 in the Local Module installed, move the JP8 jumpers in the Remote Module to the right-hand posts, and use the Remote Module’s gain-control screwdials as necessary (see Sections 3.2.3, 3.3.2, and 5.2). Standard VGA Source to Std.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 3.2 Setting the Jumpers in the Local Module (Optional) There are six user-settable jumpers inside the Local Module of the ServSwitch Brand Fiber KVM Extender. They control these options: • Whether the Local Module transmits VGA (default) or RGB video signals to the Remote Module, and if RGB, which signals and how (jumpers JP6, JP10, and JP11). • Whether the Local Module transmits HSYNC (default) or CSYNC to the Remote Module (jumper JP2).
CHAPTER 3: Configuring the ACS235A 3.2.1 THE VGA/RGB JUMPERS (JP6, JP10, AND JP11) If you’ll be using a VGA monitor in your Extender system, leave these jumpers set as they are (in their factory-default positions). But if you need to use an RGB monitor instead, take these steps (refer to Figure 3-2): • Install a jumper on JP6 if you want the Extender to add the HSYNC (horizontal sync) polarity signal to the red color signal.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 3.2.2 VGA-TO-RGB SYNC-GENERATION JUMPER JP2 For most applications you should leave this jumper installed. However, if you are using the Extender to connect a VGA video card or other VGA source to an RGB monitor, remove this jumper as shown in Figure 3-3. (This causes the Local Module to generate a CSYNC signal for transmission to the Remote Module.) Use existing sync (factory default) VGA to RGB (create CSYNC) Installed Removed JP2 Figure 3-3.
CHAPTER 3: Configuring the ACS235A 3.3 Setting the Jumpers in the Remote Module (Optional) There are six user-settable jumpers inside the Remote Module of the ServSwitch Brand Fiber KVM Extender. They control these options: • Whether the Remote Module strips the sync signals from the color signals (default) or leaves them in (jumpers JP1, JP2, and JP3). • Whether the Remote Module uses automatic (default) or manual gain control (jumper bank JP8).
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 3.3.1 THE SYNC-ON-COLOR JUMPERS (JP1, JP2, AND JP3) The Local Module of the ServSwitch Brand Fiber KVM Extender adds synchronization signals to the color signals for transmission across the fiber link.
CHAPTER 3: Configuring the ACS235A 3.3.2 REMOTE GAIN-CONTROL JUMPER BANK JP8 If you’ll be using automatic gain control (AGC) in your Extender system, leave the jumpers ON the right-hand posts of each of the three pairs of JP8 jumper posts, as shown below. (This is the factory-default setting as well as the recommended setting.) But if you’ll be controlling the gain manually (see Section 6.2), move the jumper to the left-hand posts of each of the three JP8 jumper-post pairs, as shown in Figure 3-8.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 3.3.3 VSYNC ENABLE/DISABLE JUMPER JP9 It is possible to use the Extender to connect a VGA monitor to a computer that outputs RGB video that superimposes CSYNC on the green signal. In this situation, depending on the computer, the Remote Module might express only CSYNC (composite sync) on the HSYNC lead of its VGA connector, or it might express both CSYNC on HSYNC and VSYNC (vertical sync) on the VSYNC lead.
CHAPTER 4: Configuring the ACS236A 4. Configuring the ACS236A This chapter describes how to configure the Sun model of the ServSwitch™ Brand Fiber KVM Extender (ACS236A). If your Extender is the PC model (ACS235A), see Chapter 3. 4.1 Setting the Jumpers in the Local Module (Optional) There are four user-settable jumpers inside the Local Module of the ServSwitch Brand Fiber KVM Extender.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS Figure 4-1. The locations of the ACS236A Local Module’s jumpers. 4.1.1 THE VIDEO-HANDLING JUMPERS JP2 AND JP10 Jumpers JP2 and JP10 in the Local Module control how the Extender handles video signals, depending on whether the computer outputs VGA signals to the Extender’s HD15 connectors or legacy Sun signals to the Extender’s 13W3 connectors, as well as what type of signal input the monitor accepts.
CHAPTER 4: Configuring the ACS236A VGA in, VGA out (factory default) VGA in, Sun out Sun in, Sun or VGA out Removed Removed Installed Installed Removed Installed JP2 JP10 Figure 4-2. Setting video-handling jumpers JP2 and JP10. 4.1.2 LOCAL GAIN-CONTROL JUMPER JP3 If you’ll be using automatic gain control (AGC) in your Extender system, leave the jumper ON the JP3 jumper posts. (We recommend this factory-default setting.) But if you’ll be controlling the gain manually (see Section 5.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 4.2 Setting the Jumpers in the Remote Module (Optional) There are two user-settable jumpers inside the Remote Module of the ServSwitch Brand Fiber KVM Extender. They control these options: • Whether the Remote Module uses automatic (default) or manual gain control (jumper bank JP8). • Whether the Remote Module passes a separate VSYNC signal to the monitor (default) or disconnects it (jumper JP9).
CHAPTER 4: Configuring the ACS236A 4.2.1 REMOTE GAIN-CONTROL JUMPER BANK JP8 If you’ll be using automatic gain control (AGC) in your Extender system, leave the jumpers ON the right-hand posts of each of the three pairs of JP8 jumper posts, as shown below. (This is the factory-default setting as well as the recommended setting.) But if you’ll be controlling the gain manually (see Section 6.2), which is necessary with VGA input and Sun output (see Section 4.1.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 4.2.2 VSYNC ENABLE/DISABLE JUMPER JP9 It is possible to use the Extender to connect a VGA monitor to a legacy Sun computer that outputs Sun video with CSYNC superimposed on the green signal. (If you do this, make sure that jumpers JP2 and JP10 in the Local Module are both installed; see Section 4.1.1.
CHAPTER 5: Installation 5. Installation 5.1 Guidelines and Limitations for Attaching Equipment This section discusses a few things you need to keep in mind about the types of devices you can attach to a ServSwitch™ Brand Fiber KVM Extender. As you read the rest of this section, you might want to refer to Figure 5-1, which shows how the Extenders handle the various signals they carry. For pinouts of the Extender’s connectors, see Appendix A.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 5.1.1 CPU The ACS235A Extender supports IBM PC compatible desktop CPUs; it does not support laptops. A CPU must have these kinds of interfaces to work fully with the ACS235A Extender: • Video: VGA, SVGA, XGA, or XGA-2. (Also supports most CPUs that output RGB.) • Keyboard: IBM PS/2 style (6-pin mini-DIN). (With the included keyboard-port adapter, will also support CPUs with PC/AT [5-pin DIN] keyboard ports.) • Mouse: IBM PS/2 style (6-pin mini-DIN).
CHAPTER 5: Installation 5.1.4 KEYBOARD AND MOUSE The ACS235A Extender’s keyboard and mouse interfaces are standard PS/2 type interfaces, so you can attach just about any standard PS/2 compatible keyboard and mouse to the Extender. Do not attach serial mice or bus mice to the Extender; they will not work. You can attach a PC/AT style keyboard with a 5-pin DIN connector to the Extender by using a keyboard adapter, available separately as product code FA211.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 5.2 Connecting a CPU or KVM Switch to the Local Module NOTE In the universal directions in this section and in Section 5.3, we’ll sometimes refer to separate keyboard and mouse connections even though there will only be one keyboard/mouse connection when the Sun Extender (ACS236A) is involved.
CHAPTER 5: Installation 2. Take the connectors at the other end of the cable and plug them into the equipment you want to attach. ACS235A only: Be very careful not to get the cable’s keyboard and mouse strands backwards. • If you’re attaching a CPU or a KVM switch with separate user-side connectors: Plug the included cable’s connectors into the CPU’s or switch’s video, keyboard, and mouse ports.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 5.3 Connecting User Equipment or a KVM Switch to the Remote Module NOTE FOR ACS236A Do not plug monitors, switches, etc., into both of the Remote Module’s video connectors at the same time. Take these steps to attach your user equipment directly to the Extender’s Remote Module: 1. Plug the monitor into the Remote Module’s HD15 or 13W3 female video port (labeled with the picture of a monitor).
CHAPTER 5: Installation 3. ACS235A: Run a PS/2 mouse-extension cable from the switch’s PS/2 CPUmouse port to the 6-pin mini-DIN female mouse port on the Remote Module (the port labeled with the picture of a mouse). (The switch’s CPU-mouse port must be PS/2 type.) 4A.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 5.4 Running Fiber Cable Between the Local and Remote Modules You’ll need breakout-style fiberoptic cabling with at least five fibers to connect the Extender’s Local Module to its Remote Module. What type of cable(s) you use will depend on where you’re going to run them: • Indoors: Use bulk preterminated cable (such as product code EFN1006A-ST for six fibers, EFN1008A-ST for eight fibers, etc.
CHAPTER 5: Installation CAUTION! One of the most common errors in cabling the Extender is to attach fiber strands “1” and “2” to the Remote Module backwards (strand 1 to port 2, strand 2 to port 1). Notice that while the fiber ports on the Local Module are arranged in left-to-right order as “R,” “G,” “B,” “1,” and “2,” the ports on the Remote Module are arranged in the order “R,” “G,” “B,” “2,” and “1”. 5.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 6. Operation The ServSwitch™ Brand Fiber KVM Extender Modules should begin operating as soon as they (and all attached devices) are plugged in; the green and red Power LEDs on the units’ rear panels should light. (If either LED on a Module fails to light, that Module has had an internal failure; contact Black Box Technical Support as described in Section 7.2.
CHAPTER 6: Operation Three (AGC enabled only): Low blue. Even applying max AGC, the unit can’t equalize the color signals, of which blue is at the lowest level. There’s trouble with the blue transmit diode, fiber, or receive diode. F: Contrast is turned up too high at the Remote Module for AGC to work properly. Turn the contrast down using the contrast dial on the Remote Module’s rear panel. H: HSYNC missing.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 6.2 Making Video Adjustments with the Remote Module’s User Controls If the image from your computer that’s displayed on the remote monitor is badly distorted, this might be the result of a video-signaling problem. Refer to Chapter 3 (especially Section 3.2.1) or Chapter 4 for ways in which you can modify the way the ServSwitch Brand Fiber KVM Extenders handle the sync and color signals.
CHAPTER 7: Troubleshooting 7. Troubleshooting 7.1 Things to Try First Here are a few problems that sometimes occur in a ServSwitch™ Brand Fiber KVM Extender system, along with possible causes and solutions. Problem: I can’t get a picture on my monitor screen.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 7.2 Calling Black Box If you determine that your ServSwitch Brand Fiber KVM Extender is malfunctioning, do not attempt to alter or repair the unit. It has no user-serviceable components. Contact Black Box Technical Support at 724-746-5500. Before you do, make a record of the history of the problem.

SERVSWITCH™ BRAND FIBER KVM EXTENDERS 4.2.2 VSYNC ENABLE/DISABLE JUMPER JP9 It is possible to use the Extender to connect a VGA monitor to a legacy Sun computer that outputs Sun video with CSYNC superimposed on the green signal. (If you do this, make sure that jumpers JP2 and JP10 in the Local Module are both installed; see Section 4.1.1.
CHAPTER 5: Installation 5. Installation 5.1 Guidelines and Limitations for Attaching Equipment This section discusses a few things you need to keep in mind about the types of devices you can attach to a ServSwitch™ Brand Fiber KVM Extender. As you read the rest of this section, you might want to refer to Figure 5-1, which shows how the Extenders handle the various signals they carry. For pinouts of the Extender’s connectors, see Appendix A.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 5.1.1 CPU The ACS235A Extender supports IBM PC compatible desktop CPUs; it does not support laptops. A CPU must have these kinds of interfaces to work fully with the ACS235A Extender: • Video: VGA, SVGA, XGA, or XGA-2. (Also supports most CPUs that output RGB.) • Keyboard: IBM PS/2 style (6-pin mini-DIN). (With the included keyboard-port adapter, will also support CPUs with PC/AT [5-pin DIN] keyboard ports.) • Mouse: IBM PS/2 style (6-pin mini-DIN).
CHAPTER 5: Installation 5.1.4 KEYBOARD AND MOUSE The ACS235A Extender’s keyboard and mouse interfaces are standard PS/2 type interfaces, so you can attach just about any standard PS/2 compatible keyboard and mouse to the Extender. Do not attach serial mice or bus mice to the Extender; they will not work. You can attach a PC/AT style keyboard with a 5-pin DIN connector to the Extender by using a keyboard adapter, available separately as product code FA211.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 5.2 Connecting a CPU or KVM Switch to the Local Module NOTE In the universal directions in this section and in Section 5.3, we’ll sometimes refer to separate keyboard and mouse connections even though there will only be one keyboard/mouse connection when the Sun Extender (ACS236A) is involved.
CHAPTER 5: Installation 2. Take the connectors at the other end of the cable and plug them into the equipment you want to attach. ACS235A only: Be very careful not to get the cable’s keyboard and mouse strands backwards. • If you’re attaching a CPU or a KVM switch with separate user-side connectors: Plug the included cable’s connectors into the CPU’s or switch’s video, keyboard, and mouse ports.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 5.3 Connecting User Equipment or a KVM Switch to the Remote Module NOTE FOR ACS236A Do not plug monitors, switches, etc., into both of the Remote Module’s video connectors at the same time. Take these steps to attach your user equipment directly to the Extender’s Remote Module: 1. Plug the monitor into the Remote Module’s HD15 or 13W3 female video port (labeled with the picture of a monitor).
CHAPTER 5: Installation 3. ACS235A: Run a PS/2 mouse-extension cable from the switch’s PS/2 CPUmouse port to the 6-pin mini-DIN female mouse port on the Remote Module (the port labeled with the picture of a mouse). (The switch’s CPU-mouse port must be PS/2 type.) 4A.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 5.4 Running Fiber Cable Between the Local and Remote Modules You’ll need breakout-style fiberoptic cabling with at least five fibers to connect the Extender’s Local Module to its Remote Module. What type of cable(s) you use will depend on where you’re going to run them: • Indoors: Use bulk preterminated cable (such as product code EFN1006A-ST for six fibers, EFN1008A-ST for eight fibers, etc.
CHAPTER 5: Installation CAUTION! One of the most common errors in cabling the Extender is to attach fiber strands “1” and “2” to the Remote Module backwards (strand 1 to port 2, strand 2 to port 1). Notice that while the fiber ports on the Local Module are arranged in left-to-right order as “R,” “G,” “B,” “1,” and “2,” the ports on the Remote Module are arranged in the order “R,” “G,” “B,” “2,” and “1”. 5.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 6. Operation The ServSwitch™ Brand Fiber KVM Extender Modules should begin operating as soon as they (and all attached devices) are plugged in; the green and red Power LEDs on the units’ rear panels should light. (If either LED on a Module fails to light, that Module has had an internal failure; contact Black Box Technical Support as described in Section 7.2.
CHAPTER 6: Operation Three (AGC enabled only): Low blue. Even applying max AGC, the unit can’t equalize the color signals, of which blue is at the lowest level. There’s trouble with the blue transmit diode, fiber, or receive diode. F: Contrast is turned up too high at the Remote Module for AGC to work properly. Turn the contrast down using the contrast dial on the Remote Module’s rear panel. H: HSYNC missing.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 6.2 Making Video Adjustments with the Remote Module’s User Controls If the image from your computer that’s displayed on the remote monitor is badly distorted, this might be the result of a video-signaling problem. Refer to Chapter 3 (especially Section 3.2.1) or Chapter 4 for ways in which you can modify the way the ServSwitch Brand Fiber KVM Extenders handle the sync and color signals.
CHAPTER 7: Troubleshooting 7. Troubleshooting 7.1 Things to Try First Here are a few problems that sometimes occur in a ServSwitch™ Brand Fiber KVM Extender system, along with possible causes and solutions. Problem: I can’t get a picture on my monitor screen.
SERVSWITCH™ BRAND FIBER KVM EXTENDERS 7.2 Calling Black Box If you determine that your ServSwitch Brand Fiber KVM Extender is malfunctioning, do not attempt to alter or repair the unit. It has no user-serviceable components. Contact Black Box Technical Support at 724-746-5500. Before you do, make a record of the history of the problem.
