3.5.3 Communication via analogous modem
3.5.3.1 Conditions
For a communication via analogous modem, you have to set "‘RS232"’ as communication in the system
menu-BIOS of the ZK-MasterIV (see chapter
). The baud rate of the terminal and the connected
modem must be coordinated. The timeout must be set dependent on the line quality of the telephone
network (Which disturbance sources the cable is exposed to?). The worse the line quality the higher the
timeout should be set. The modem to which the terminal is to be connected has to be configured via the
COM-interface of a PC. The steps listed below refer to the tested and recommended "‘Devolo-MicroLink
56k Fun II"’ modem.
3.5.3.2 Connection
The analogous modem is connected to the
COM-interface of the PZE-MasterIV. Use a Null-
modem-adaptor or another cable that is assembled
corresponding to the figure.
Note that at the site of the ZK-MasterIV
no
connections are bridged. You can use a Sub-D
9-pole 1:1 cable as an extension between the Null
modem adaptor and the terminal.
