1. Introduction
When connecting Maintenance Tool through G-50A, normal communication may not be performed if Firewall, the security function of Windows XP, has wholly been validated.
(* In E-Mail mode and MN converter connection, it is not related)
Therefore, the setting of Firewall should partially be changed following the procedure indicated in Chapter 3 How to change the setting of Firewall.
2. Applicable case
(1) Should the following symptoms occur at the Address Searching of OC (051~100), it may be possible that the communication from G-50A can not be received normally as the communication port to use has been blocked by Firewall.
