purchase a compatible power cord or use an adapter. The Matrix supports both
110 V, 60 Hz and 220 V, 50 Hz power systems. There is a power on indicator
light on the front panel

2.4 Control Inputs
The matrix can be controlled from either RS-232 or through IP.
2.4.1 Basic Unit with RS-232 Control (no IP)
The basic system without IP feature actually has 2 separate and independent RS-
232 control ports.
The main RS-232 port is on a screw terminal and the auxiliary port is on an RJ45.
Caution on RJ45 Control Input
Both matrices with IP control and those without have an RJ45
connector next to the RS-232 screw terminal.
This RJ45 connector is a 10/100 Base-T Ethernet for the matrix with
IP, or a secondary RS-232 Serial control port for those matrices
without IP feature. It is easy to confuse their function.
A sure way to tell if the RJ45 control input is LAN or Serial is by the
presence of little LED indicators to the sides of the connector. If the
connector has these lights, then it is a LAN connection, otherwise it is
an RS-232 serial connection.
