11.2.- MODBUS/TCP
This protocol is a variation of the MODBUS/RTU protocol that has been specially designed to work with
TCP/IP networks. The queries from various devices can be optionally accumulated in a battery. This
will allow various devices to send data to the QNA500 8IO analyzer at the same time and the analyzer
will respond to each specific query. The following port must be used when establishing communications
through the Ethernet port: 30003
11.3.- ZMODEM
This international standard protocol can be used to download files and its main feature is based on the
repositioning of any frame. This is quite important in communications via modem, where existing delays
or silences in the lines can lead to communication errors. This standard protocol has been specially
designed for an optimum operation in these situations. The following port must be used when
establishing communications through the Ethernet port: 14001 (telnet zmodem) or 14002 (RAW
zmodem).
