The 2711P-RN8 module is a DH+ communication module for 400 and 600 series terminals from the Allen-BradleyPanelView Plus product range. DH+ network technology is designed for industrial applications. It is an easy-to-implement network technology which enables simple communication between computers, PLCs, and SLCs. The recommended cable for use with connections with SLC-5/04 controllers is shielded twisted cable like the Allen-Bradley 1770-CD cable. The recommended cable for connections with PLC-5, PLC-5C, and PLC-5E controllers is shielded twisted cable (like the 1770-CD). The recommended cable for connections with ContolLogix controllers like the 2711P-RN8 module is shielded twisted cable (like the 1770-CD). The 1770-CD cable can be ordered from Allen-Bradley in 30.5-meter (100-foot) increments.

The 1770-CD cable is a Belden 9463 twin axial cable which has conductor material that is 20 AWG tinned copper with a 0.038-inch diameter, 2 conductors that are used for cable construction, a cable capacitance of 19.7 pF/foot, a cable nominal inductance of 0.12 uH/foot, a cable impedance of 78 Ohms, and the cable attenuation at 1, 10, 50, 100, 200, and 400 MHz is 0.6, 2.1, 5, 7.5, 11, and 16 dB/100 meters, respectively. The weight of the cable is 36 pounds per 1000 feet. The maximum recommended pulling tension is 48 pounds and the minimum bend radius is 2.4 inches. In storage, the 2711P-RN8 module must be kept in an area with an ambient temperature between -13 and 158 degrees Fahrenheit. For optimal operation, the ambient temperature range should be maintained between 32 and 131 degrees Fahrenheit. The recommended lower and upper thresholds for the non-condensing relative humidity are 5 and 95%, respectively. The maximum operating altitude for the 2711P-RN8 module is 2000 meters.
