Delivery status
The RS232 interface of the base modules and the virtual COM-Port of the base
module alpha BM 120 (USB-Port) are set to the parameters 115,200 baud, 8 data
bits, no parity bit, 1 stop bit.
The setting of the virtual COM-Ports at the base module alpha BM 110 and
alpha BM 130 is carried out similar to this.
The measuring interval of the sensor module SM 230 is set to 60 seconds.
The measuring range of the PT1000 sensor is set to the range -40 °C ... 110 °C, at the
analogue inputs, it is set to 0 - 2.5 or 0 - 10 V.
Initial state of the base module after connecting
All base modules can be connected to a PC by means of a serial cable.
An external voltage source is required for the power supply. For this, the base
modules are equipped with a socket for the connection of an external power supply
unit. After connecting the power supply unit to the RS232 cable, the base module
automatically switches to receive mode.
Base module alpha WSN BM 110
In case the base module is connected to a PC over a LAN connection, an external
voltage source has to be used for the power supply. For this, the base module is
equipped with a socket for the connection of an external power supply unit.
An exception is the possibility of voltage supply over the LAN connection, in case
the LAN is equipped with an appropriate voltage source 802.3af mid span power
passthrough (PoE=Power over Ethernet). After connecting the power supply unit
and a LAN cable or only a LAN cable in case of PoE feeding, the base module
automatically switches to receive mode. In case of voltage supply of the LAN module
over Ethernet, the power supply unit should be separated from the unit.
Base module alpha WSN BM 120
In case the base module is connected to a PC by means of an USB cable, no ex-
ternal power supply unit is necessary. The base module is automatically energised
over the USB port. After connecting the USB cable, the base module automatically
switches to receive mode. In case the base module is connected with a PC over
USB, no power supply unit should be connected.
Base module alpha WSN BM 130
In case the base module is connected to a PC over a WLAN connection, an external
voltage source has to be used for the power supply. For this, the base module is
equipped with a socket for the connection of an external power supply unit. After
connecting the power supply unit, the base module automatically switches to receive
mode.
