There are two methods of wiring an Ethernet Serial Server to a sign:
METHOD 1: If a sign has a SERIAL I/O terminal block, then wire the
Ethernet Serial Server to this block (above).
METHOD 2: Otherwise, wire the Ethernet Serial Server directly to the
SERIAL PORT on the sign's Controller board (right).
