Installing the VS-3232A in a Rack 5 Installing the VS-3232A in a Rack This section describes what to do before installing on a rack and how to rack mount.
Connecting a Single VS-3232A 32x32 Audio Matrix Switcher 6 Connecting a Single VS-3232A 32x32 Audio Matrix Switcher To connect the VS-3232A as illustrated in the example in Figure 4, do the following1: 1. Connect up to 32 balanced audio sources2. 2. Connect up to 32 balanced audio acceptors2. 3. Set the DIP-switches (see Section 7.5). 4. If required, connect a PC or controller to the RS-232 port (see Section 7.6.1) or the RS-485 port (see Section 7.6.2) or the ETHERNET port (see Section 7.8). 5.
Connecting a Single VS-3232A 32x32 Audio Matrix Switcher 6.
VS-3232A 32x32 Audio Matrix Switcher Configurations 7 VS-3232A 32x32 Audio Matrix Switcher Configurations The VS-3232A belongs to a series of 32x32 matrix switchers, including the VS-3232V and the VS-3232Vxl, and as such, can interconnect with them. The following sections describe: • The VS-3232A configuration setups (see Section 7.1) • Various matrix configurations (see Sections 7.2, 7.3, and 7.4) • The DIP-switch setup (see Section 7.5) • How to connect a control interface (see Section 7.
VS-3232A 32x32 Audio Matrix Switcher Configurations switching an input to an output on one machine, switches the same input to the same output on the other machines in the FOLLOW state. DIP 5 defines whether the VS-3232A unit can communicate with other switchers via a common control line. Set DIP 5 to: • ON, to enable the Follow-System configuration setup • OFF, to disable the Follow-System configuration setup Set the machine number on each machine to a different value.
VS-3232A 32x32 Audio Matrix Switcher Configurations • Pressing the FOLLOW button on the CV switcher too, sets it searching for the other machines in the FOLLOW state At this state, all three switchers follow each other: for example, switching input 1 to output 16 on the English language audio switcher, switches input 1 to output 16 on the French language audio switcher and on the CV switcher.
VS-3232A 32x32 Audio Matrix Switcher Configurations The BREAKAWAY and FOLLOW front panel buttons have no effect in the Master/Slave configuration setup since the connected machines act as one unit in one box. DIP 6 determines the operation mode of each unit within the Master/Slave configuration setup. DIP 6 is set to: • ON, for the Slave units in the configuration setup • OFF, for the Master unit in the configuration setup Set the machine number on all the machines to the same value.
VS-3232A 32x32 Audio Matrix Switcher Configurations 7.1.3 The Follow-System versus the Master/Slave Configuration Setups The example illustrated in Figure 10 shows three 32x32 matrix switchers: one composite video switcher and two audio switchers. DIP 5 is set to ON on all the units. DIP 6 is set to OFF on the CV VS-3232Vxl switcher and on the A1 English language VS-3232A audio switcher. DIP 6 is set to ON on the A2 French language VS-3232A audio switcher.
VS-3232A 32x32 Audio Matrix Switcher Configurations 7.2 Assembling a Multi-channel Audio Switcher The example in Figure 11 illustrates a 4-channel 32x32 configuration consisting of two VS-3232A units. Broadcasting applications often use four channels, to broadcast stereo audio sound in two languages (say, English and French) or to produce surround sound. DIP 6 is set to OFF on the master unit and set to ON on the Slave unit.
VS-3232A 32x32 Audio Matrix Switcher Configurations 7.3 Connecting the VS-3232A as a Companion to the VS-3232V(xl) You can connect the VS-3232A as an analog audio companion to the VS-3232Vxl 32x32 Video Matrix Switcher, as illustrated in the example in Figure 12. To connect the VS-3232A as a companion to the VS-3232Vxl, do the following: 1. Connect the required inputs and outputs to the VS-3232A and the VS-3232Vxl. 2. Connect the two switchers via the RS-232 or RS-485 control interface (see Section 7.6).
VS-3232A 32x32 Audio Matrix Switcher Configurations 7.4 Connecting the VS-3232A as a Companion to a Multi-channel Video Switcher You can connect the VS-3232A to a multi-channel system such as a switcher for YUV (RGB) by combining three VS-3232Vxl units1.
VS-3232A 32x32 Audio Matrix Switcher Configurations Set the DIP-switches as follows: Table 5: DIP-switch Settings for VS-3232A and VS-3232V(xl) Switchers Machine Name VS-3232V(xl) VS-3232A Follow-System Master/Slave 1 Machine # 2 3 4 5 6 Y (G) ON OFF OFF OFF ON OFF U (B) ON OFF OFF OFF ON ON V (R) ON OFF OFF OFF ON ON Audio OFF ON OFF OFF ON OFF Connect the communication line between the switchers via the RS-232 or RS-485 control interface as section 7.6 describes. 7.
VS-3232A 32x32 Audio Matrix Switcher Configurations 7.5.1 Setting the Machine # To control a unit remotely via RS-232, RS-485, IR or the Ethernet, each unit has to be identified via its unique Machine #.

VS-3232A 32x32 Audio Matrix Switcher Configurations With a Null-modem adapter Set DIP 7 OFF ON 1 2 3 4 5 6 7 8 Without a Null-modem adapter Set DIP 7 ON ON 1 2 3 4 5 6 7 8 Figure 15: Connecting a PC to two VS-3232A Units You can connect any of the following: • The 9-pin D-sub COM port of the PC to a VS-3232A unit1 (see Section 7.6.1.1) • Two VS-3232A units1 or a VS-3232Vxl video matrix switcher2 connected to a VS-3232A audio matrix switcher, (see Section 7.6.1.
VS-3232A 32x32 Audio Matrix Switcher Configurations To connect a PC to the VS-3232A unit, without using a Null-modem adapter: 1. Connect the RS-232 9-pin D-sub port on your PC to the RS-232 IN 9-pin D-sub rear panel port on the Master VS-3232A with a 9-wire cable1 to the RS-232 9-pin D-sub port on your PC. 2. Set DIP 7 ON2 (disabling Null-modem adapter use) on the VS-3232A unit. 7.6.1.
VS-3232A 32x32 Audio Matrix Switcher Configurations To connect an RS-485 connector on one VS-3232A unit to an RS-485 connector on one or more video switchers (from the series of 32x32 or 16x16 matrix switchers), as Figure 17 illustrates: 1. Connect the “A” PIN on the first VS-3232A unit to the “A” PIN on the VS-3232Vxl unit and to all the other video units. 2. Connect the “B” PIN on the first VS-3232A unit to the “B” PIN on the VS-3232Vxl unit and to all the other video units. 3.

VS-3232A 32x32 Audio Matrix Switcher Configurations Usually the easiest method is to choose the sync source from the first video machine and then connect all the terminal block connectors, as Figure 18 illustrates. In this case, set the first machine to select the sync source from the external sync connector or from the INPUT # 1 connector1. This sync is now available to the other machines via the RS-485 terminal block connector, as the examples in Figure 16, Figure 17 and Figure 18 illustrate.
