Wireless RS-232 to Bluetooth Converter
|In its simplest use it can be thought of as a RS-232
to wireless Bluetooth converter. Since RS-232 ports are considered a legacy item in most PC’s and laptops a converter is needed to connect a computer to an ajet printer. Using this accessory you have the convenience of it being wireless.
Even if you have access to a PC or laptop some customers object to having computer on the factory floor. Many have used a handheld in this case but a handheld terminal (sometimes called a KID) has a small LCD screen and a limited keypad. These limitations can cause difficulties, frustration and errors. With the Bluetooth accessory the user can program an ajet printer using a computer with a full screen and keyboard and the computer doesn’t have to be in the factory.
To connect the ajet printer to your PC first install an inexpensive Bluetooth dongle into a USB port. After the computer installs the drivers insert the Bluetooth adaptor into the ajet and ask the computer to find it. After it does so enter the passcode 1234. Windows will likely assign several COM ports only one of which works as a serial port. Use a terminal emulator such as Tera Term and try each. After it connects you can use it just as if you had a cable connection to the ajet.
Using the Wireless RS-232
to Bluetooth Converter with other devices
The abm Bluetooth converter can be used with other devices that have RS-232 jacks.
The ajet printer has +5 volts available on pin 9 of the jack which is used to power the converter. With other devices the converter can be fitted with a barrel jack for use with a common wall mount power supply. Click on the photo to the left for a close up view.
