The Mercury Hub  
From Resource Data Management  
Description  
The Mercury Hub is a device that allows up to 10 RDM controllers to be connected to an IP network, with out  
the need for individual IP Futura modules. The Hub can be mains powered, or powered from 2 connected  
Mercury controllers. There are 10 RS232 connections for linking to Mercury controllers, 2 standard ethernet  
hub (10baseT) connections for other network devices and a dedicated ethernet Uplink port.

Connection to Mercury Controllers:  
Using a standard CAT5 patch lead, connect the serial output of the RDM Controller to one of the RS232 ports  
of the Mercury Hub.  
RS232 Lead Lengths  
For mains powered hubs, patch lead maximum length must not exceed 15 metres. (ports 1 - 10)  
For Mercury powered hubs, inputs 1 and 2 patch leads must not exceed 5 metres, ports 3 - 10 must not  
exceed 15 metres.  
The 3-character address that will be seen on the system front end is determined by the position of the two  
Network ID rotary switches and the port the controller has been connected to.  
Connection to other IP equipment  
Use a standard CAT5 patch lead to connect other IP equipment to the Mercury Hub (such as a Futura IP  
module) into the 10Base T ports 1 or 2.  
Connection to another Mercury Hub or Other Ethernet Hub/switch  
Use a standard CAT5 patch lead from the Uplink port into a standard IP port on the next Hub.  
Connection to a Data Manager/Director  
Use a standard CAT5 patch lead and connect the Data Manager or Data Director to one of the two 10 Base T  
ports.

10 Base T connectors  
The three 10Base T connectors have 2 leds on them: The green LED; when static, indicates that the  
connection to the device is good, the green LED then flickers when data is being transmitted.  
The amber LED indicates there is an error or fault on that channel.  
Network ID  
The 3-character network ID is made up from the positions of the 2 rotary switches and the RS232 connector  
number. We recommend that the 2 rotary switches are set to the Bay number and that the case sections are  
plugged into their corresponding RS232 port numbers.  
E.g. Bay 10 case 2:  
The 2 rotary switches set to "1" and "0", controller plugged into port 2. The ID then is seen as "102" at the  
system front end.

Note that case number 10 would plug into RS232 port 0 (right most port) and come through as "100".  
ID for equipment with rotary switch’s.  
For RDM products that use the 3 rotary switch’s for the network ID (such as Powertrays), the ID will follow  
what is set on the controller local switch’s and NOT the port position on the Hub.
