gram’s user guide.
b. If you are using a terminal emulation program:
Press the Space or Esc key several times, at one-second intervals,
until the > prompt is shown, indicating that the command
interface is ready to accept input. The diagnostic interface has an
automatic baud-rate detector which synchronize with your data
rate.
If the unit does not recognize your data interface arrangement,
try the following settings:
• Data Bits = Eight
• Parity = None
• Stop Bits = 1
• Data Rate = 9600 bps
• Flow Control = None
• Terminal Emulation/Mode = ANSI
NOTE: The DIAGNOSTIC PORT supports autobaud at 2400, 4800,
9600, 19200, and 38400 bps baud rates.
