Wiring for RS-485 MultiHop Radios
Connecting dc power to the communication pins will cause permanent damage. For FlexPower devices, do not apply more
than 5.5 V to the gray wire. The FlexPower Multihop radios operate equally well when powered from the brown or gray
wire; it is not necessary to supply both. The power for the sensors can be supplied by the radio's SPx terminals or from the
10 to 30 V dc used to power the radio.

Wiring for DX80...E Radios
Connecting dc power to the communication pins will cause permanent damage. The integrated battery DX80...E radios
may also be powered by 10 to 30 V dc. The power for the sensors can be supplied by the radio's SPx terminals or from the
10 to 30 V dc used to power the radio.
The BAT connection is a low voltage connection to the internal battery. Remove the internal battery if a low voltage source
is connected to the BAT terminal. When powering the device from the integrated battery, the BAT connection must remain
open.

Terminal Blocks and Wiring for M-H1* Models
Connecting dc power to the communication pins will cause permanent damage. For the DX8x...C models, PWR in the
wiring diagram refers to V+ on the wiring board and GND in the wiring diagram refers to V- on the wiring board. Do not
exceed analog input ratings for analog inputs. Only connect sensor outputs to analog inputs.
