3.4.6 Line connection
This section explains the connection (dialing) with the partner devices for the purpose of data communication with
external devices using the modem functions.
In case of notification to a pager receiver, the line is connected while the notification is being processed. The
connection processing such as a connection request (Y11) to I/O signal is, therefore, unnecessary.
*1
*1 The data for connection indicated in this section should be set to perform the notification processing
(1) Requirements for connection
Complete the following settings and registrations in advance.
• The initial settings for the Q series C24 as shown in Page 131, Section 3.4.2
• The registration of the data for initialization as shown in Page 134, Section 3.4.3
• The registration of the data for connection as shown in Page 139, Section 3.4.4
• The initialization of the modem/TA connected to the Q series C24 side as shown in Page 144, Section 3.4.5
• In addition, both the initialization and line connection can be conducted simultaneously by designating the
data for initialization and data for connection to perform connection processing. For the data setting for
initialization to perform initialization and line connection simultaneously, see Page 131, Section 3.4.2,
Page 144, Section 3.4.5. Explanation on the above-mentioned setting is omitted in this section.
(2) Registering the data for connection using GX Configurator-SC (Settings on the
modem function system setting screen)
The number of the data for connection that is used for line connection in order to perform data communication
with the external device is registered on the GX Configurator-SC's "Modem function system setting" screen.
The following explains the number designated by the "Connection data number" item on the GX Configurator-
SC's "Modem function system setting" screen.
• When line connecting from the Q series C24 side
*1
• Data number for connection designation area (address: 35H (53))
The data for connection registration number is designated.
BB8H to BD5H (3000 to 3029): Data registered to the Flash ROM by the user
8001H to 801FH (-32767 to -32737): Data registered to the buffer memory by the user
*1 The addresses shown in parentheses below indicate the addresses of the buffer memory where the setting values for
this item on the "Modem function system setting" screen are stored.
• When line connecting from the external device
Since the line connection processing is not necessary on the Q series C24 side, connecting data registration for
line connection and data number setting for connection are not needed.
