ZyWAN User Manual Configuring the ZyWAN

Field/Option Explanation

ATDT or DCD: Connect if either ATDT### message is received

or if the Data Carrier Detect (DCD) signal on the serial port is

asserted. If the ATDT message is received, it is compared

against the Matching Dial String in the Host Connection rows to

find which IP address to use for connection. If the DCD is

received, the ZyWAN is connected to the IP address of the first

Host Connection row with an empty field for the Matching Dial

String.

Serial Driver

Select whether to use the Native Linux (ttyS) serial driver, or

the Eurotech Ltd driver which allows for half-duplex RS-485

communication. Presently the Eurotech Ltd driver is not

available.

The Host Connection Table is part of the Terminal Client configuration:

At least one row must be configured in the Host Connection Table for it to work

properly:

Button Explanation

Insert Row#

Each row of the Host Connection Table exists as a set of

properties in a numbered table row within the Terminal Client

configuration. In order to insert a row in the table, enter a

number in the box between 1 and one greater than the highest

number of rows. Then click the Insert Row# button to insert a

blank row. This row must be filled in with all data required.

Note that when adding or deleting rows of a Host Connection

Table, make sure to click the Insert Row# or Delete Row#

buttons within the brown section of the Terminal Client, not the

buttons at the very bottom of the main table.

Delete Row#

In order to delete a row of the Host Connection Table, enter a

number in the box between 1 and the highest number of rows.

Then click the Delete Row# button to delete the row. Once a

row is deleted, it cannot be restored without inserting a row

and entering the data again.
