Supply power to the SLTA-10 after it is connected to the
desired network. Table 5 has the specifications for power
inputs to the SLTA-10. The barrel connector input, J2, is a
standard female power plug with a 2.1 mm inside diameter
and a 5.5 mm outside diameter (LZR Electronics part number
HP114A, Radio Shack catalog number 274-1569, or

Power supply jack J3 provides screw terminals with a
provided Weidmüller input connector (PN 11261). This allows
the SLTA-10 to connect to a 9 to 30 Vac/Vdc power supply.
