Audio Connection

Audio for VRS can be from the following sound devices:

1. the standard computer sound in (1 channel only). Just plug the audio source in.
2. The standard computer sound in split to 2 mono channels. Buy a simple Y cable from your local electronics to wire 2 mono sockets to a stereo plug. Then using Channel Properties assign one channel to "left mono" and the other to "right mono".
3. Multiple sound cards in one PC. Depending on slots and resources you can install up to 3 sound cards in one PC. Each stereo input can be split (ie. a total of 6 inputs). This requires a bit more technical work than a multichannel card (next).
4. Multiple channel sound cards. There are many multichannel sound cards on the market today (see www.nch.com.au/vrs/acc/index.html to find links). VRS can be setup to use these channels. You can probably also install multiple devices to get more channels (check with the manufacturer first).
5. USB sound devices. USB devices usually can be used with a hub to connect many devices to one PC. Most modern USB sound devices let you do this (but check with the manufacturer before purchasing). Stereo devices can be split (see above).
6. Professional Telephony Boards [for Call Recording]. Professional telephony boards including CURL and CAHTA can be used directly. They can usually be purchased in 2/4/8 line versions and many can be installed in one PC. They also have the advantage of allowing caller ID and hardware control.
7. the noticable exception is VRS does not record through voice modems. For that you need the TRX (see TRx Manual Call Recorder).
   

Telephone Call Recording

For recording telephony calls you should either:

1. Telephone Interface Connectors for each line. In USA or Canada, Radio Shack (Tandy) supply a FCC approved unit for $US22 (cat no. 43-228A or 43-1236). But there are many better quality units available.
2. A Professional Telephony Board (multiline). Both CURL and CAHTA make these in 2/4/8 and more line version.

Hardware Record Control

If you are using VRS with specialist record devices (eg. Professional Call Record Interface Units), your supplier may be able to provide a premade cable to connect between the device and the (Game Controller - Joystick) port of the computer running VRS.

If you have connected the cable, and the VRS Options Box reports that no device is connected, you may need to enable a 4 button Game Device using the Windows Control Panel (under Game Controllers).

Devices can also be connected to a COM port.

For each channel, you must select the correct port and connection that will be used to control that line.

Technical Information

The following information is intended only for those who wish to create or link their own equipment. It requires are good understanding of electronics, computer hardware and game controller ports.

In order to trigger VRS in hardware mode, the hardware must connect the button switch for the line. For line 1 this is button 1 of port 1. Line 2 is button 2 of port 1. Line 5 is button 1 of port 2 and so on. Your equipment must "press" (connect to ground) these buttons to start recording, and disconnect when recording is to stop.

Important: The cable will also need to notify Windows that it is correctly connected. This can only be done by connecting the x and y axis of all ports to the +5V pin (see the diagram below).

Before you will be able to use the port, you must have a 4 button Game Device enabled from the Control Panel (under Game Controllers). A useful test is to connect a normal joystick and see if it triggers recordings on hardware lines.
