Question: How do I configure the ATW-CHG3 and ATW-CHG3N Recharging Stations?
Answer: Drop-in chargers for wireless transmitters make many people’s jobs easier. Audio-Technica offers the ATW-CHG3 Two-Bay Recharging Station, which allows you to simply place a 3000 Series 4th Generation transmitter powered by AA rechargeable NiMH (nickel-metal hydride) batteries into one of the station’s two docks to charge it for the next use. (Transmitters do not come with batteries; see below for our recommended NiMH batteries.) While it is recommended that you power down the ATW-T3201 and ATW-T3202 transmitters prior to recharging, if left on, a transmitter will power down automatically and stop transmitting an RF signal when it is placed into the recharging dock. If left in the powered-on state, the transmitter will power on and begin transmitting the RF signal when you take it from the charger. You can’t get much easier than that.
Audio-Technica also offers the ATW-CHG3N Networked Two-Bay Recharging Station, which connects to a network so the charging status of transmitters can be monitored. Using one ATW-CHG3N networked station allows you to connect up to four non-networked ATW-CHG3 and pass power and network data through a link cable. To do so, you will need to use the appropriate number of AT8687 Link Kits, each of which consists of a link cable, link joining plate, and screws for attaching the joining plate between two stations. To set up your configuration of connected stations so they can be monitored via the dedicated software you will need to properly set the ID switches on your non-networked chargers. Your networked charger will always have the number “1” as its ID. You will need to assign a unique ID number (2 through 5) to the non-networked chargers, using the ID selector switch located on the bottom of each station. Note, these ID switches must be set prior to connecting the stations together since the joining plates will cover the switches. The first link cable will run from the “OUT” link jack of the networked station to the “IN” link jack of a non-networked station. The “OUT” link jack of that station may then be connected to the “IN” link jack of the next station, and so on, until you reach the maximum of five linked stations.
Once connected, you can power up to five of your recharging stations with a single AD-SA1230XA AC Adapter (sold separately). This allows you to connect one ATW-CHG3N and four ATW-CHG3 and use a single AC Adapter to power them all. In this setup, both the power and the data will be carried over the link cables. Additionally, if you do not plan to connect your recharging stations to a network, you can connect up to five ATW-CHG3 stations and power them all with a single AC Adapter.
When you place a transmitter into a charging dock, the station’s LED status indicator will light solid red, indicating that the batteries are charging. (It may take a few moments for the light to come on.) If there is a charging error, the status indicator will flash red. An error can result from a poor connection, in which case you will need to remove the transmitter and reinstall it in the dock. Attempting to charge incompatible batteries, such as non-rechargeable alkaline batteries, will also cause an error. When the batteries are fully charged, the indicator will light solid green. One additional installation note: When using the ATW-T3201 body-pack transmitter, make certain the belt clip is mounted so the opening is near the charging contacts. If the belt clip is mounted in the opposite direction, the transmitter will not fully seat in the charging dock.
There are many NiMH batteries on the market, ranging in price and features. Not all batteries are created equal, and with rechargeable batteries there are a few points to remember. First, out of the box, most are not 1.5 volts like standard alkaline batteries are, and the NiMH batteries will degrade as they are used and recharged. So you should monitor the voltage and performance of the rechargeable batteries and replace when needed. A good rule of thumb is to change your rechargeable batteries once every year. You may also consult with your battery manufacturer for tips on maximizing their product’s performance. Audio-Technica recommends the following seven batteries for use in our products.
