Seral Port Settngs
GateDX-P can use the COM1–COM9 serial ports.
The user must enter the following port settings.
• Use/Do not use (ON/OFF)
• Type (RS-422-A/485 or RS-232-C)
• Baud rate: 4800, 9600, 19200, 38400 bps
• Parity bit: NONE, ODD, EVEN
Recorder Settngs
GateDX-P allows simultaneous connection with any combination of 16 DX100p/
DX200Ps.
The user must enter the following recorder settings.
• Port (COMx or Ethernet)
• Address number (if a COM port using RS-422-A/485 is selected)
• IP address or host name (if Ethernet is selected for the port)
• User name (if Ethernet is selected for the port)
• User ID (if Ethernet is selected for the port)
• Password (if Ethernet is selected for the port)
• Automatic Model Determination
If communication settings are entered correctly, the models, number of measurement
channels, and number of computation channels are identified by the software.
Scan Interval
A scan interval from 0.5 to 3600 seconds is selected for each of the 16 DX100P/
DX200Ps.
Note
When connecting to DAQLOGGER and acquiring data from the DX100P/DX200P, if GateDX-P’
s scan interval is longer than that of DAQLOGGER, DAQLOGGER logs the same data
repeatedly until the next Gate-DXP scan interval. Therefore, it is recommended that GateDX-P’
s scan interval be set to a value smaller than DAQLOGGER’s scan interval.
Communcaton Retry
Using the Configurator, you can turn communication retry ON and OFF, and set the retry
interval.
• When Communcaton Retry Is OFF
After detecting that communications were cut, no attempts are made to reconnect.
• When Communcaton Retry Is ON
After detecting that communications were cut, the software attempts to reconnect
after the retry interval has elapsed. Even if the reconnection resulted in an error,
the software waits again for the retry interval to elapse, then attempts another
reconnection. This process repeats until a valid connection is opened.
A communication retry interval of 30 to 3600 seconds can be entered.
Note
GateDX-P considers communications to have been cut in the following circumstances.
• If the executable function requests data from a DX100P/DX200P but no response is
received within 10 seconds.
• f the software detects that the TCP/IP connection was dropped when the executable
function is connected to the DX100P/DX200P via Ethernet.
