nominal power 6-36 VDC, 1.6 A maximum must be used. Otherwise, safety of the product may
be impaired. In case of doubt, please consult the local authorized suppliers.
Input voltage to the unit must be well filtered and within the nominal range of 6-36 VDC. The maximum
rated power consumption of the device is 10 watts, but actual power is typically much less. The power
supply must be capable of supplying the expected maximum power for the installation. For expected
power requirements in common configurations, see "Technical Specifications
on Page 53.
ETH— Ethernet connection port. These ports support both device management and payload data
transport. This is a standard RJ-45 jack and features MDIX auto-sensing capability, allowing straight-
through or crossover cables to be used.
Connecting to the unit via SSH supports device management and provides a similar user interface
available using the unit's serial COM port.

USB Port—This port provides a USB-C connection to a laptop or PC. The port provides a local console
for management of the device. A standard host-to-USB-C cable may be used.
COM Port—This connector serves as the serial interface port for payload data. The COM port serves as
the primary interface for connecting the unit to an external DTE serial device supporting RS-232 or RS-
485. If necessary, an adapter may be used to convert the unit's RJ-45 serial jack to a DB-9F type (GE
MDS 73-2434A25).
TransNEXT typically uses the unit's USB port to access the device management interface
NOTE
(CLI). As an alternat access method typing "+++" on the COM port (at roughly half second
intervals) will cause it to drop out of payload mode and present the CLI interface. Issuing a
logout command will revert the unit to payload data mode.
The COM port supports a serial data rate of 1200-115200 bps (115200 default, asynchronous only). The
unit is hardwired as a DCE device.
