Alternative Port Capabilities
The LX-4000 Series offers extended capabilities beyond traditional RS-232 communication uses. For
example, a port with specialized hardware attached can be configured to monitor temperature and
humidity remotely. The following sections present some of these capabilities.
Sensor (Temperature/Humidity) Ports
NOTE: Refer to Appendix A for Temperature/Humidity sensor technical specifications.
You can configure ports to act as temperature and humidity monitors when connected to an In-Reach
Temperature/Humidity Sensor. The Temperature/Humidity Sensor provides an accurate
measurement of the temperature/humidity in the area in which your LX Series unit is placed.
The following section explains how to connect and install the sensor.
Connecting the Temperature/Humidity Sensor
A 10’ Male RJ-45 to Male RJ-45 straight-through cable (P/N MX-151-3027) connects the temperature/
humidity sensor to an LX-4000 async port. The LX unit can be configured to support the sensor on
any async port other than the DIAG port (port 0).
To connect the sensor:
1. Connect one end of the RJ-45 double-ended straight through cable to the temperature/humidity
sensor. The maximum length of this cable is 50 feet.
