Configuring via the Web Server Configuring the System The Host/Loop Communications tab enables you to: • Configure the following host settings: - Connection type (host or web server) - Communications type - Baud rate - Port number - Time sync • Configure the loop baud rate for communication among downstream panels. Steps: Use the descriptions in the following table to configure the settings: Table 2-1: Configuration > System > Host/Loop Communications Tab Field Descriptions Host/Loop Setting Description Host Connection type Specifies the type of physical connection between the host and the Gateway panel. If you are connecting from a host software system such as WIN-PAK, select one of the following three connection options: Direct via TCP/IP - Host connects directly to the panel using the TCP/IP protocol. Reverse TCP/IP - Panel connects directly to the host system using the TCP/IP protocol. You must enter the host IP address in the Host IP Address field. The communication is not encrypted. Direct via RS-232 - Host connects directly to the panel via the RS-232 protocol. Hub Mode (modem) - Host and the panel both connect to a modem. If you will be connecting to the panel through the NetAXS™ web server, click None. (Currently not supported) Comms Type Specifies the type of communications. Ack/NAK - Provides a response (either an acknowledgement or a non-acknowledgement) in a transmission between the host and panel(s). This is the recommended communications type. Non Ack/NAK - Does not provide a response (either an acknowledgement or a non-acknowledgement) in a transmission between the host and panel(s). 12 www.honeywell.com
