Serial Ports
The FOX DA has two serial ports that can be connected to a host
device such as a computer running the HyperTerminal utility,
an RS-232 capable PDA, or a control system. These ports make
serial control of the DA possible. The serial ports are:
• The rear panel RS-232 port on a 3-pin captive screw
connector
• The front panel Configuration (RS-232) port, a 2.5 mm
mini stereo jack
The protocol for both ports is as follows:
• 9600 baud
• no parity • 8 data bits
• 1 stop bit • no flow control
