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.
