Operation
Unlike an Ethernet hub, which broadcasts all messages received out all ports, the DRL-7xx
series route Ethernet messages to the appropriate port. In other words, it prepares the network
for optimal bandwidth conditions, reduces the number of collisions.
The DRL-7xx series supports 10BaseT (10 Mbps) or 100BaseT (100 Mbps) on the M-12
ports. Each port, independent of the others, will auto-negotiate the speed and duplex mode.
This allows both 10 Mbps (full or half duplex) and 100Mbps (full or half duplex) devices to
be connected to the same DRL-7xx series Switch.
Performance Specifications
The performance specifications are as follows. For complete technical specifications,
including switch dimensions, refer to Appendix A.
Table 1: Performance Specifications
Ethernet Switch Type Unmanaged
Ports 10BaseT/100BaseTx M12
Required Voltage 9-36VDC (See Appendix A for power consumption for each model)
Ethernet Standards IEEE 802.3 (10BaseT), 802.3u (100BaseTX), 802.3x (Full Duplex)
Ethernet Protocols All standard IEEE 802.3 protocols supported
Speed Per Port 10 Mbps/100Mbps
Ethernet Isolation 1500 Volts RMS (for 1 minute)
Operating Temperature -40 to 80°C
Humidity 5 to 95% (non-condensing)

Power LEDs
The Power LEDs indicate the switch is correctly powered.
LED State Meaning
Off Device is powered Off
Green Power is connected correctly
DRL-780 / DRL-781 / DRL-782
There are two Power LEDs on the DRL-78x Switches. PWR1 is used for primary power, and
PWR2 is used for secondary power. Both indicate if power is being applied to the respective
terminal.
Note
The DRL-780/DRL-781/DRL-782 operates while either (or both)
DRL-750
The DRL-750 has only one Power LED. The LED will be lit if power is applied to one or
both of the +24VDC terminals.
PWR1/PWR2 LED lit.
In power redundancy mode, both PWR1 and PWR2 will be lit.

LED Indicators
IP67 Industrial Ethernet Switches Hardware Reference Guide
ACT/LNK LEDs
The Ethernet activity (ACT) is reported through one LED. There is one of these LEDs per
M12 port.
LED State Meaning
Off There is no activity on this port
Flashing Green Communication activity detected.
10/100 LEDs
These LEDs indicate the communication speed detected on the port. There is one of these
LEDs per M12 port.
LED State Meaning
Off There is no proper Ethernet connection (link)
Yellow A 10 Mbps (10BaseT) connection is detected.
Green A 100 Mbps (100BaseTx) connection is detected.
between the port and another Ethernet device.
Make sure the cabling is correct and that all cables
are plugged securely into the ports, at both ends.
For Ethernet wiring directions, refer to Section 5.
