Use the following information to connect the DeviceMaster UP 2-port.
1. Connect your serial devices to the appropriate serial port on the DeviceMaster UP
using the appropriate cable. You can build your own cables or loopbacks using the
appropriate discussions:
• Serial Terminal (4) Signals (1E) on Page 56
• Serial Terminal (8) Signals (2E) on Page 57
• DeviceMaster 1E (Serial Terminals) Cables and Loopbacks on Page 63
• DeviceMaster 2E (Serial Terminals) Cables and Loopbacks on Page 65
Note: Refer to the hardware manufacturer's installation documentation if you need help
with connector pinouts or cabling for the serial device.
2. Verify that the devices are communicating properly. Use the appropriate table for
information about the LEDs, which may provide information about the installation.
The STATUS LED on the device is lit, indicating you have power and it
has completed the boot cycle.
Note: The STATUS LED flashes while booting and it takes approximately

Bootloader completes the cycle, the LED has a solid, steady light
that blinks approximately every 10 seconds.
If the LINK (green) LED is lit, it indicates a working Ethernet
LINK
connection.
If the ACT (yellow) LED flashes, it indicates network activity.
