Is a proper modem used?
Inapplicable modems
The following types of modems cannot be used:
• A terminal adapter connected to the ISDN line cannot be used on the PC side (GP’s
receiving side uses an analog modem.)
• A modem which can be used only after connecting to a specific operation center such
as Air’H of Willcom, Inc. (former DDI Pocket, Inc.)
Applicable modems
The following types of modems can be used:
• Only a modem which uses RS-232C can be connected to the GP.
• A Windows
®
-supporting modem which can call the modem connected to the GP
• A modem which supports AT commands
• A modem which allows automatic reception on the GP side
• A modem which is capable of hardware-flow control
• A modem which can return strings with result commands
Is the modem connected to the Display properly?
Cause
A USB-to-serial conversion cable must be used. The cable may be disconnected from
the modem or GP. The modem may not be turned ON.
Solution
Check that the modem is properly connected (GP
→
Serial conversion cable
→
Modem).
Also check that the modem has been turned ON. Pro-face recommends the use of the
USB-Serial (232C) Conversion Cable : “CA6-USB232-01”(sold separately) for the con-
nection between GP and modem. The following conversion cable can also be used.
