Appendix – TEMP Protocol
AVAILABLE TO SPECIAL ORDER
Tempest can optionally provide a firmware load that facilitates TEMP over RS485, suitable for interfacing to an Ethernet
adapter. TEMP is a lightweight proprietary ASCII based protocol, intended for rapid integration into management systems.
With TEMP and a suitable RS485 to Ethernet adaptor connected to the DEC DMX connectors, your DEC may be configured and
monitored over an IP network.
Please contact factory for ordering information.
