Everex WC-31 User Manual

Everex Communications, Inc
WC-31 User's Manual:
WC-31 is a 2.4Ghz 802.15.4 wireless digital analog I/O transceiver which
is used in energy management, building control, HVAC applications. It
communicates with the host and/or other WC-31 units in the unlicensed 2.4Ghz
ISM band. It is powered by a 24VAC power source. The unit consists of the
following I/O functions:
1. Three relays: 1A/30V, normally open relays.
2. Two thermistor inputs: Connect to 30K thermistor, the unit can provide
remote temperature reading.
3. Serial communication bus: Other serial peripheral devices can be
connected to the unit for providing expansion of the additional digital
inputs/outputs or other control function, for example, thermostat or HVAC
controller.
One of the important features of WC-31 is its mesh network, self-forming
and self-healing capability. Each WC-31 unit is a router which can relay
information and command to other WC-31s. If one of WC-31 in the network path
becomes non-functional, WC-31 can automatically seek other WC-31 to reform
the network connection.
Installation:
There are a 12 pin screw terminal and a 4 pin serial communication
connector. The 12 pin screw terminal provides connections to thermistors for
temperature measurement and to other HVAC devices. The 4 pin connector
provides serial communication and 24VAC power to other serial device, such as
thermostat or HVAC controller. Please refer to the picture below for pin
assignment of each connector. WC-31 should be mounted high up on the wall to
provide maximum RF communication range.
