APPENDIX E. MAXIMUM 8032-5 (TAN CABLE) CABLE LENGTHS

The 8032 Multiplexer is a low power device, that can be physically located at a considerable
distance from the Datalogger. The limitations to the maximum distance between the 8032
multiplexer and the datalogger are mostly due to the voltage dropped by the 8032-5 MUX cable
over its length. Factors such as ambient temperature, number of 8032 Multiplexers ("daisy-
chain" configuration) and system battery voltage need to be considered in determining the
maximum 8032-5 cable length.
For a single 8032 Multiplexer under normal operating conditions (System Battery = 12V,
ambient temperature = 20° C), the maximum recommended cable length from the Datalogger to
the 8032 Multiplexer is 4588 feet (≈1400 m). Figure 14 displays the maximum recommended
cable length for various Datalogger, Battery Voltage and ambient Temperature combinations.
