Q: What is the number of the network port used by E-RDS?
A: The port number used by E-RDS for communication with UGW is "443".
If this setting is changed, an error occurs during communication with UGW. Therefore this
setting should not be changed unless otherwise instructed.
No.14
Q: After the setting for E-RDS was made, the IP address of the host machine was changed. In
that case, is it necessary to execute COM-TEST again?
A: It is not necessary to execute COM-TEST again because the IP address used by E-RDS is
automatically changed. However, it is necessary to turn OFF and then ON the main power
of this machine to reflect the change in the setting of the IP address
