Remote Operation
27
When connected to a PC with a Windows operating
system, the Product will communicate through a PC COM
port. Make sure the COM port parameters are set to:
• 9600 Baud
• No Parity
• 8 data bits
• 1 stop bit
• Hardware handshake set to off
Remote Commands
A remote command is made up of alphanumeric
characters. The first character of a command must be
alphabetic. The alphabetic characters can be upper or
lower case.
• Special characters are:
• Carriage return (CR)
• Line feed (LF)
• Space (SP)
• Backspace (BS)
• Escape (ESC)
The Product will do a command when it receives a
carriage return and/or line feed. Alphabetic characters are
not case sensitive. When you type in a command, the
backspace deletes the last recorded character and the
escape key discards the complete command. When a
command is complete, the Product sends a response that
ends with a carriage return and line feed to the PC. Unless
other data is sent back from the Product, the response is
“OK” if the command is accepted by the Product. When a
command is not accepted by the Product, an error code
shown in Table 8 is sent to the PC.
Table 8. Error Codes

While the Product is operated from the front panel (local
mode) the remote interface will not respond to a command
until the command REMOTE is sent to the Product through
the USB port.
