(Figure 2 - Side view of RSCOM2A)
Note - Two of the internal jumpers inside the RSCOM2A converter need to be moved from their factory default position
to function properly with SMART Link-485, shown in Figure 3.

Function Test
Prior to completing final connection to the CR6 Datalogger, it is recommended to test the operation of the
SMART Link-485. Ideally this is completed prior to grouting the unit into the drill hole.
(Figure 4 - Components needed for testing operation of SMART Link-485)
A 12V power source is required for the SMART Link-485 and the RSCOM2A, a 12V battery works well.
Wiring connection paths are shown previously in Figure 1. The RSCOM2A ships with a ribbon cable with an
RJ11 connector on one end and a 9-pin serial connection on the other.
First, connect the RJ11 to the RSCOM2A and the serial connection to a straight-through serial cable connected
to a serial port on a computer. Next launch a terminal emulation program (HyperTerminal was used for this
document) on a computer.
