1. OVERVIEW
Z-397 WEB converter is used to connect various devices with serial RS-485 interface to a
TCP/IP-based Ethernet network. With it, it becomes possible to control these devices from any
network location, including Internet. Good setup flexibility makes it possible to use the converter
on any Ethernet networks. Certain operation modes designed for use in Access Control
Systems (ACS), significantly extend the ACS capabilities even to use of cloud technologies.
Using FREE software COM2IP (see website for details), it is possible to add a virtual COM port
onto a PC which will be connected to RS-485 port of a Z-397 WEB converter. This configuration
allows operating software which was designed to work with previous generation RS-485
converters.
Operation modes.
Through its Ethernet port, Z-397 WEB converter supports operation via TCP/IP protocol in three
main operation modes:
1) Web Client mode: the converter controls the ACS system via its website. (e.g.
www.guardsaas.com) ;
2) TCP Server mode: the converter listens for connections from a remote PC running client
software (such as GuardLight, Guard Commander, Guard
see website);
3) TCP Client mode: the converter attempts to connect to a remote PC running server software
(e.g. GuardLight, ZProxy).
By using the drivers on a PC, virtual COM ports are created which are linked to the converter.
This allows to use any software, which can work with standard COM ports, with this converter.
The converter has two RS-485 lines, one of them has galvanic isolation from the rest of
converter. It supports the NVT open protocol (Network Virtual Terminal, per RFC2217) for data
transmission and line control.
Configuration and firmware updates may be performed either locally via USB port, or remotely
via Telnet protocol. Converters have a special switch that disables remote configuration, for
better system security.
