RS485 connection (optional)

To connect your PoE sign to your network using an RS485 connection, remove the plate on the rera of the sign to access
the hard wire connections and terminate the network. Adaptive recommends performing these steps before mounting the
sign.
To utilize the optional RS485 network connection on an Alpha 4000 RGB PoE sign follow the steps below to
connect the sign to an RS485 network.
1. Begin by removing the (4) 6-32 tamper proof screws holding the removable cover for the Ethernet connection.
· T15 Pin in Torx Driver is required (not supplied).
· Take care not to lose screws.
· See: Back View Cover Removed from previous page
2. Choose one of the .41-inch knockout to remove for your installation location. Two (2) are provided. Exercise caution
when removing either knockout so as to avoid the knockout blank unintentionally entering the inside of the unit. ANY
OTHER ENTRY HOLES ADDED TO THE SIGN WILL VOID WARRANTY.
· RS-485 wiring, conduit, and conduit fittings for making connections to the sign are not supplied.

5. Make the minimum customer RS485 communication connection to the sign
· For the RS485 connection a wire gauge of 28AWG (minimum) to 18AWG (maximum) is required;
torque RS485 connection terminal points to a maximum of 5 lb-in.
· A shielded RS485 cable is recommended. Connect shield of cable to SHLD terminal of sign and to
chassis ground of transmitting device.
· RS 485 connection to D+ and D- terminals of sign.
· If the RS485 signal from the transmitting device is isolated, then connect EGND terminal of sign
to the signal ground terminal the transmitting device.
· If the RS485 signal from the transmitting device is not isolated, the GND terminal of the sign can
be left open
Once all connections have been made attach the provided ferrite around the RS485 cable
·
(ferrite must be attached within the sign)
