The TCP/IP Modbus Interface Connector provides a way for connecting to customer controls through Modbus. This connection provides translated Modbus data from the engine to the compressor controls and also from compressor controls back to the product link module for display in the back office. Refer to REHS9763 for additional information for configuring Modbus.RS485/RS232 Modbus Interface Connector:

443-8463 Antenna As (Adhesive mount external antenna for cellular and satellite radios)
Note: Installations of the adhesive mount external antenna will have difficulty acquiring the proper adhesive properties when both the antenna and the mounting surface are below certain temperatures. For installations on a metal surface, temperatures under −6.67° C (20° F) will cause improper adhesion. For installations on a non-metallic surface, temperatures under −1.11° C (30° F) will cause improper adhesion. It is necessary to increase the temperature of the adhesive mount external antenna, and the mounting surface prior to installation. Apply direct force until the adhesive mount antenna can hold on its own. Full adhesion can take over 24 hours in colder climate.
When using thePL641 radio with an external antenna, the antenna must be located more than 200 mm (7.87 inch) from the machine operator to comply with FCC regulations for RF human body safety. If the PL631 Satellite antenna radio is used the distance from the machine operator increases to 500 mm.
When installing a cellular radio with external antenna, ensure the external antenna, is mounted a minimum of 250 mm (9.84 inch) away from any metal structures that extend above the mounting plane. Any metal obstruction for the radio will create diminished cellular and GPS connectivity.
When using the PL641 radio with external antenna, the external antenna must be mounted in a horizontal orientation on a flat surface.
The radio or antenna needs to have a clear line of sight of the sky. Usually, the canopy/container roof will provide an optimal view of the sky with minimal blockages.
To utilize the GPS Signal, the cellular radio or antenna may be mounted under a non-metallic cover, but not a metallic one.
Do not mount the radio or antenna in an area that will expose the radio or antenna to extreme conditions of heat. Exposure to high heat may make the radio or antenna inoperable. Refer to Table 1.
Locate the radio and antenna so that the radio and antenna connectors are not exposed to high-pressure spray or underwater immersion. Exposure to high-pressure spray or underwater immersion may compromise the connector seals and lead to connection failure.
Mount the antennas more than 1000 mm (39.370 inch) from radiation sources of similar frequencies and more than 250 mm (9.84 inch) from radiation sources of other parts of the spectrum. The lists
