Inst allat ion
Inst allat ion Overview
To install and set up the SW VGArs / Ars Series switchers, follow these steps:
1 Turn all of the equipment off. Ensure that the video and audio sources (computers, stereos, tape decks or other devices), the SW VGArs / Ars switcher, the output devices (projectors, speakers), and contact closure control device are all turned off and disconnected from the power source.
2 If you are going to connect VSW I AAP remote controls to one or more inputs, identify the version of the SW VGArs / Ars circuit board (to ensure that the VSW I AAPs will work with this version) and configure the switcher’s jumpers. See “Identifying the Board Version and Setting the SW VGA/Ars Jumpers” on page 2-10.
3 Mount the switcher. See “Mounting the Switcher” on the next page.
4 Attach the cables. See “Rear Panel Features and Connections” later in this chapter.
5 Connect power cords and turn on the devices in the following order: · Output devices (projectors, monitors, speakers) · SW VGArs / Ars Series switcher · Contact closure/RS-232 controller · Input devices (computers, audio sources)
6 Select an input using the front panel buttons, or the contact closure or RS-232 controller.
7 The picture should now appear and sound should be audible (SW VGA Ars models). If not:
· Ensure that all devices are plugged in and receiving power.
· Check the cabling and make adjustments as needed. · Select a different input that is known to work to check
for a display and sound.

M ount ing t he Sw it cher
If you are going to connect VSW I AAP remote controls to one or more inputs, identify the version of the SW VGArs / Ars circuit board (to ensure that the VSW I AAPs will work with this version) and configure the switchers’ jumpers before mounting the switcher. See “Identifying the Board Version and Setting the SW VGA/Ars Jumpers” on page 2-10.
Rack m ount ing
UL guidelines
The following Underwriters Laboratories (UL) guidelines pertain to the installation of the switcher into a rack (figure 2-1).
1. Elevated operating ambient — If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consider installing the equipment in an environment compatible with the maximum 122 °F (50 °C) ambient temperature (Tma) specified by Extron.
2. Reduced air flow — Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.
3. Mechanical loading — Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
5. Reliable earthing (grounding) — Reliable earthing of rackmounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (such as the use of power strips).

If you plan to use the switcher with VSW I AAP remote controls, you must configure the switcher. It is more convenient to do this before installing it in a rack or furniture and making connections.
Using the SW VGA/Ars switcher with VSW I AAP control panels requires you to set internal jumpers in the switcher. When you open the switcher, you can also check the circuit board installed in the switcher to ensure that it is compatible with the VSW I AAP control panels.
On the VSW I AAP remote control, ensure that jumper J6 is installed. Refer to the VSW I AAP manual for details.
1. If applicable, disconnect all power to the switcher and any attached devices.
2. Remove the eight screws from the switcher (three on each side of the switcher and two on top) (figure 2-8). Remove the two connector nuts from the Remote connector ( 6 on figure 2-3 and figure 2-4) and each VGA connector ( 2 and 4 on figure 2-3 and figure 2-4) on the rear panel of the switcher. Lift the top cover off of the switcher.

Remove (2) nuts each side of each 9-pin and 15-pin connector.

These jumpers enable/disable VGA connector pin 5 (control) for each input. Close (install) the jumper for a specific VGA input to allow the VSW I AAP’s “show me” signal to select that input.
When an input is not connected via a VSW I AAP, that input’s jumper should be in the default (open) position.
Each jumper, when closed (installed) allows the switcher to receive the “show me” signal from the VSW I AAP on that input’s VGA connector. When a jumper is open (removed) that input cannot receive the signal.
Auto switch mode must be disabled when using the switcher with one or more VSW I AAP remote controls. If the auto switch mode is enabled, the input cannot be selected using the “show me” function.

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command character sequence. When a command is valid, the switcher executes the command and sends a response to the host device. All responses from the switcher to the host end with a carriage return and a line feed (CR/LF = ), which signals the end of the response character string. A string is one or more characters.

When a local event, such as a front panel operation or error condition, occurs, the switcher responds by sending a message to the host. The switcher- initiated messages are listed below: (C) Copyright 2002, Extron Electronics SWy VGArs, Vx.xx The switcher issues the copyright message when it first powers on. Vx.xx is the firmware version number. Inn·All The switcher issues the Inn message when a front panel input selection operation occurs. n is the input number. Reconfig The switcher initiates this message when there is a change in an audio model’s audio gain setting. Sig·n·n·n·n·n·n The switcher initiates this message when there is a change in the status of an input. n = 1 indicates the video signal is present, n = 0 indicates the video signal is not present. There are as many ns in the switcher-initiated message as the maximum number of inputs for the models (2, 4, or 6). For example, the response Sig·1·1·1·0·1·0 shows that the input signal is present on inputs 1, 2, 3, and 5, and that no signal is present on inputs 4 and 6.
Error responses
When the switcher receives a valid SIS command, it executes the command and sends a response to the host device. If the switcher is unable to execute the command because the command is invalid or it contains invalid parameters, the switcher returns an error response to the host. The error response codes are:
E01 — Invalid input channel number (out of range) E06 — Invalid input channel change (auto-switch mode
active) E09 — Invalid function (mode) parameter E10 — Invalid command E13 — Invalid value (out of range) E14 — Illegal command for this configuration

Cont act Closure Rem ot e Cont rol
The Remote connector also provides a way to select an input to the switcher using a remote contact closure device. Contact closure control uses pins on the Remote connector that are not used by the RS-232 interface. The contact closure pin assignments are shown in figure 4-1 on page 4-2.
To select a different input number using a contact closure device, momentarily short the pin for the desired input number to logic ground (pin 5). To force one of the inputs to be always selected, leave the short to logic ground in place. The short overrides front panel input selections.
