Cascaded Installation via RS485 Connection

Two RJ45 ports are provided on the front of models IPDU-S4 and IPDU-S8. These are used when multiple units are connected
together (cascaded) and controlled as one system using the RS485 Connect method (see page 8). Cascading enables the
monitoring of all sensors and outlets from up to 17 IPDU-S4 or IPDU-S8 (or any combination of each model).
Connect installation, connect a CAT5/5e/6 patch cable with RJ45 male connectors on each end (wired straight thru, pin 1 to pin 1,
pin 2 to pin 2, etc.) between the "Cascade" ports as shown in the image below. The maximum distance from the Master to the last
Slave can be no more than 1000 feet. With this properly connected and configured (pages 38 and 85) , the user can monitor the
sensors and outlets of all systems from either a single connected terminal (page 6) or through the Web Interface.

GSM Modem Connection

(IPDU-S4 and IPDU-S8 Models only)
If alert notifications via SMS to a cell phone are desired, a GSM modem can be connected to the USB port on the IPDU-S4 / -S8
models. With a GSM modem connected, a user can receive SMS alert messages directly on their cell phone.
modem is powered by the USB port.
A GSM modem that has been tested and is confirmed to be compatible with the IPDU-S4/ -S8 is the iCON 452. To order this
modem, contact NTI and ask for the ENVIROMUX-3GU.
Note: The modem connected to the IPDU-Sx will send SMS messages only. No access to the IPDU-Sx is possible
through the modem.
