Introduction
ETC’s VCC-28 USB programmable microphone is designed to integrate with Twisted Pair
Solutions’ WAVE Dispatch Communicator. In conjunction with a wireless headset and phone, the
VCC-28 not only allows an operator to access all the functions of a dispatch software, but provides
multiple hardware features. This powerful tool has five mechanical/hardwired keys to allow
toggling between modes, twelve software hot-keys to control panel functions, and twelve software
hot-keys that are user programmable while in WAVE. Features include the following:
• RJ-9 ports for Phone and Handset
• RJ-25 port for a Wireless Headset Device (such as Plantronics CA12CD)
• Speaker Out Jack
• Foot Switch Input Jack
• Record Out Jack
• USB 1.0 or 2.0 compliant port
• Enumeration LED
• Record Out Switch for recording options
• Microphone
• Speaker Volume Control Knobs
• Speaker Activity Indicator LEDs
This guide will cover configuring the VCC-28 in Windows XP Pro, Windows 7, and WAVE Dispatch
Communicator (the basics only). Linux is noted in this manual, although the VCC-28 has not been
tested with it. The key/functions described in this manual assume WAVE Dispatch Communicator
to be installed and running. The screen shots in this guide were taken with a VM-4; your screens
will show a VCC-28 device name.
IMPORTANT: Windows and USB Sound Device Settings
In Windows OS (all versions through Vista) the sound device is not seen as a removable device.
When a USB sound device is removed, the Registry corrupts. Upon reconnection, Windows
defaults back to the sound device and the settings hard-coded in the chip-set and does not retain
the USB settings. TToo wwoorrkk aarroouunndd tthhiiss iissssuuee,, pplleeaassee sseeee tthhee AAppppee
In Windows 7, Microsoft addressed the problem of USB sound devices defaulting back to hardcoded levels in the chip-set when they are disconnected and reconnected. The levels set for the
device will remain the same if you unplug it then plug it back in. However, on a computer with
multiple sets of speakers (internal and external), Windows 7 will revert back to whatever speaker it
sees as the default device. Upon reconnecting your ETC equipment, the system will recognize it
but may not choose it as the active device. If your system does not see the ETC equipment as the
default sound device, you still need to choose it each time the USB cable is disconnected.

VCC-28 Key Pad
The VCC-28 key pad (see Figure F page 6) has five hardware keys that control certain functions of
the key pad. These keys are illuminated when they are active.
A
Key Latch: Changes the number keys (1 thru #) from momentary into latching action. When the
Key Latch key is illuminated (latched), the number key chosen (illuminated) will stay latched
“ready”. When the operator initiates PTT from the VCC-28 keypad, headset adapter, footswitch, or
software, the chosen channel will transmit. The same channel will stay ready until that key is
pushed again to unlatch it, another channel is chosen, or the Key Latch function is turned off. IE:
The operator wants channel 5 to stay ready for an extended period. He/She pushes the Key Latch
key (which illuminates), then selects the 5 key (which illuminates). The operator can now use the
PTT function from the VCC-28 keypad, headset adapter, footswitch, or software as needed to talk
on channel 5. When he/she is done with channel 5, another channel can be chosen and latched
ready, or the Key Latch key can be pushed and all keys will revert to momentary action.
B
Head Set: Enables –or- disables the wireless headset. When this key is illuminated (latched), all
available audio input is routed to the headset. When the Head Set key is not illuminated, the VCC28 routes the USB audio to the external speakers, and the incoming phone audio to the phone
handset. The headset PTT function is activated only when the Head Set key is illuminated
(latched).
C
Num Lock: Toggles the number keys (1 thru #) between numerical –or- programmed hot key.
This key works the same as a traditional keyboard Num Lock key. When it is illuminated (latched),
a number key acts like a numerical key and does not produce any programmed hot key sequence.
When it is not illuminated, a number key will produce the programmed hot key sequence
associated with it.
*
Num Lock overrides Key Latch* IE: The operator has Key Latch illuminated (latched) and is PTT
on channel 5. If he/she pushes Num Lock, channel 5 is disconnected and no longer active as a
transmit channel.
D
Phone Only: This key is only functional when the Phone key is illuminated (latched) and external
phone calls are being routed to the wireless headset. The Phone Only key toggles between phone
audio only –or- phone audio summed with USB audio getting through to the wireless headset. ALL
transmitting is disabled when Phone Only is illuminated (latched).
E
Phone: Determines how external phone calls will be routed. When this key is illuminated
(latched), the telephone handset is bypassed and the phone call is routed directly to the wireless
headset. The operator would pick up the handset to answer a call, set it aside, and use the
headset to speak into and listen from. When the call is completed, the operator would put the
handset back on the telephone cradle. This is necessary because the head set does not have the
ability to physically pick up or hang up a phone call. When the Phone key is not illuminated, the
phone handset works as a traditional handset (operator speaks into and listens from the handset)
and the Phone Only key is N/A.
For clarification of USB / PHONE audio paths and PTT Functional path, please see
Flowcharts 1, 2 , 3, 4 on pages 7 , 8, 9. 10.
