The Alpha Ethernet Adapter does not have its own power supply. It receives its power from a pin in the sign's RS232 jack. Some Alpha signs do not have power in their RS232 jacks, so they can't be used with the Alpha Ethernet Adapter.
This Tech Memo lists the Alpha signs that can be used with the Alpha Ethernet Adapter and the Alpha signs that cannot be used.
NOTE: Signs that do not have power in the RS232 jack can use a different Ethernet Adapter, such as the MSS100 or the MSS485. Please contact Alpha-American Programmable Signs at 800-223-4636 for additional information and prices. |
