Weidmuller Wireless Ethernet Modem & Device Server WI-MOD-E-G/A User Manual
antennas should be mounted as per the manufacturer's instructions, with the parabolic grid at the "back" and the radiating
element pointing in the direction of the transmission.
Ensure that the antenna mounting bracket is well connected to "ground/earth".
2.2 - Power Supply
The WI-MOD-E module can be powered from a 9 - 30VDC
power supply. The power supply should be rated at 1 Amp.
The positive side of the supply must not be connected to earth.
The supply negative is connected to the unit case internally.
The DC supply may be a floating supply or negatively
grounded.
The power requirements of the WI-MOD-E unit are shown in
the following table
Voltage
Quiescent
TX @100mW
TX @ 400mW
A Ground Terminal is provided on the back of the module. This Terminal should be connected to the Main Ground point of
the installation in order to provide efficient surge protection for the module (refer to the Installation Diagram).
2.3 - Serial Connections
RS232 Serial Port
The serial port is a 9 pin DB9 female and provides for connection to a host
device as well as a PC terminal for configuration, field testing and for
factory testing. Communication is via standard RS232 signals. The WI-
MOD-E is configured as DCE equipment with the pinouts detailed below.
Hardware handshaking using the CTS/RTS lines is provided. The
CTS/RTS lines may be used to reflect the status of the local unit's input
buffer. The WI-MOD-E does not support XON/XOFF.
Example cable drawings for connection to a DTE host (a PC) or another
DCE hosts (or modem) are detailed above.
