NOTE: Connecting the SHIELD depends on the sign to which you are connecting. If your
sign has only one RJ11 jack (a combined RS232 and RS485), the shield wire
should not be connected to the red terminal of the modular network adapter.
However, if your sign has two RJ11 jacks, the shield wire should be connected to
the red terminal. Additionally, in the case of a sign with two RJ11 jacks, always
connect the 4-conductor RS485 cable to the RS485-only jack.
