Connection and sensor planning
V2.0.4 shows the box connected before the first receiving card or after the last receiving card, or connected directly to a computer by serial cable. Follow these diagrams when planning the system. The earlier page wording “between two receiving cards” is not the arrangement described in this specification.
The original listing also mentions humidity detection and temperature/humidity module connection. V2.0.4 confirms temperature detection and sensor ports but does not specify a humidity-measurement function. Confirm the required sensor and system support before selecting this product for humidity monitoring.
