NOTE:
•To use the E-mail connection mode, the version of G-50A should be above 2.60.
•When using E-mail connection mode, the local G-50A is required to be initially set with Maintenance Tool and
the mail address by the G-50A initial setting tool.
- For each mail address, it is required to obtain and set an exclusive one. To transmit mail via an internet
provider, obtain the mail address from the provider. When a mail server is existing on the LAN, obtain the
mail address from the LAN administrator.
- Set the [Pop receive interval] within 3 minutes. However to monitor operating status [Operation Monitor], set it within 1
minute.
- Setting of initial information to G-50A can not be executed from Maintenance Tool. Make sure to set it from the G-50A
initial setting tool locally. If dialup connection environment is available, it can be set from a remote position.
(For detail, please refer to 6-1 Mail Basic Setting in the instruction manual of the G-50A initial setting tool.)
• The communication speed under E-mail connection mode largely depends on the transfer rate of each mail
server. Under the circumstance, the action of Maintenance Tool may take a lot of time under some internet
environments or routing mail servers.
