The Dogcatcher is a physically and electronically robust device which collects data from a serial RS232 port and records the data to a USB memory drive.
Recording Media Size
The Dogcatcher serial data logger records data to USB sticks of any size, from kilobytes to tens of gigabytes. The size of the output file is limited to 4GB maximum per the FAT file system standard. For best results with a nearly full USB stick, Kingston drives are recommended.
The Dogcatcher’s red and green LEDs serve as diagnostic aids. The red LED shows that serial data has arrived (a slow flash) and that the user may remove the USB stick (off or flashing). The green LED shows the presence of power (on or flashing) and that the USB thumb drive is recognized (LED on).
DOGCATCHER RS232 DATA LOGGER SPECIFICATIONS
Internally fused at 0.75A. Typical current is 0.1A. Actual current draw depends on memory stick used.
9600 baud, 1 stop bit, no parity, no flow control. RS232 standard voltages.
Writes data after 64 bytes received, or 7 second timeout between received bytes.
Writes data to the file CAPTURE.TXT on flash drive, or if that file is present, appends data to the end of the file.
USB Flash drive must be formatted for a FAT file system with a cluster size of 512 bytes. The majority of flash drives satisfy these requirements. Security enabled drives are not supported.
