InGateway Documentation, Release 0.0.1
• Challenge Confirm: Enter the challenge code again to confirm the setting.
• Unstructured address: specifies the IP address of the certificate.
• RSA Key Length: specifies the length of the RSA key. The valid value range is 128-2048, and the unit
is bit.
• Poll Interval: specifies the interval at which the device queries the current certificate status from the
server. The valid value range is 30-3600, and the unit is second.
• Poll Timeout: specifies the maximum duration for querying the certificate status. The device considers
the certificate application fails when the timeout period expires. The valid value range is 30-86400,
and the unit is second.
• Revocation: enables or disables certificate revocation.
–
CRL URL: specifies the URL of the certificate revocation list (CRL) distribution point.
–
OCSP URL: specifies the URL of the Online Certificate Status Protocol (OCSP) server. Gener-
ally, it is the same as the URL of the CA server.
Note: When using a certificate, ensure that the system time is consistent with the actual time.
4.5 Industrial Interfaces
The IG902 provides industrial interfaces to connect to terminals with industrial interfaces. It forwards
data from these terminals to the upstream device wirelessly through the gateway, implementing wireless
communication between the terminals and upstream device. Industrial interfaces of the IG902 include serial
interfaces and I/O interfaces. Serial interfaces include RS232 and RS485 interfaces. I/O interfaces include
digital input, relay output, and analog input interfaces.
4.5.1 DTU
4.5.1.1 Serial Port
To ensure proper communication between the IG902 and terminals, you need to set its serial port parameters
based on serial port settings on the terminals.The serial port parameters are described as follows:
• Serial Type: The type of serial port 1 is RS232, and the type of serial port 2 is RS485, which cannot
be changed.
• Baudrate: specifies the symbol transmission speed measured by the number of symbols transmitted
per second.
• Data Bits: specifies the number of data bits in communication.
• Parity: specifies the error check method used in serial communication. Generally, parity check or no
check is performed.
