Network Router 13-6
Connecting to RS422 Devices (Remote 3GS Panels)
A 3GS panel can be connected to a remote PC by placing a LDAC or Mini-LDAC close to the panel and connecting
this to the Network Router as outlined in the following table.
The panel can now be placed up to 1.6 kilometres from the network router, depending on the type of cable used.
Connecting Multiple Network Routers
Should you wish to control more than 8 panels from one PC serial port, you can cascade multiple network routers
together by connecting any of the Slave Output Channels from one Network Router to a Master Input Channel
(D Type connector) of another router. Cascading four routers together allows one serial port to control up to 29 3GS
panels.
Connecting Network Router to Remote Master Input
To connect from one network router to another remote Network Router, wire as outlined in the following table.
Powering a Network Router
A Network Router is powered from a 12 volt DC supply. A power cable is provided which will enable connection to
any 12 DC Europlex PSU. Each Network Router requires 700mA for proper operation. The Power LED (Red) on the
front panel is on when the unit is powered up.
