MAX-CSE/MAX-CSD10 Operation/Reference Guide
Power over Ethernet (PoE) wiring
PoE can be used to indirectly provide DC power to this 802.3af-compliant device via the unused wire
pairs in the UTP or STP Ethernet cable (RJ-45 pins 4, 5, 7, and 8).
PoE power is overridden if a direct power feed (via the rear 2-pin PWR connector) is detected.
Any 802.3af-compliant PoE switch (such as the NXA-ENET24 PoE) can automatically detect the MAX
device by its authenticated PoE signature and sense its required load before applying power to the PoE
Ethernet port on a target device.
Ethernet LEDs
MAX-CSE and MAX-CSD10 units use a standard CAT5 Ethernet cable to provide 10/100 network
connectivity to the network. LEDs indicate communication activity, connection status, speeds, and mode
information as described in FIG. 7.
DB9 Device Port: Connections and Wiring
FIG. 8 shows the connector pinouts for the rear RS-232/RS-422/RS-485 (DB9) Device Port on both the
MAX-CSE and MAX-CSD10 units. This port supports most standard RS-232 communication protocols
for data transmission.
