3.3.3.1 TCP/IP
Data
Mode
With the onboard TCP/IP stack, the HW 86012/22 allows for very simple system integration.
A serial data stream can be applied to the module’s RS-232 host application interface
without any protocol implementation. A TCP connection transfers the data through the
CLDPS network to the LAN and WAN to any TCP/IP based server. There, the serial data
stream can be terminated in a TCP socket connection.
The HW 86012/22 module may be configured as a TCP/IP server (listening port) or client
(active port) as required by the application. Protocols implemented in the software stack
include TCP, IP, ARP, ICMP and DHCP. Call control on the serial interface allows to setup
and release a connection easily. The TCP/IP mode can only be applied in CLDPS radio
mode.
