Electrical connection 4.1 Power supply 24 VDC or 27,2 VDC PC-2000-W is powered with a stabilised 19.2-30VDC supply, same power supply as the CPU unit ADA-2000-E. If battery backup is used the power supply must be able to deliver 27.2VDC in order to recharge the battery. Depending on how much load there is on the 24VDC circuit we recommend to use a 24VDC battery with 1.3-3Ah capacity.
11 to 20. -Band cable CSD26/1.5m is connected between K1 on ADA-2000-E and K9 on PC-2000-W, this cable is used for digital outputs 1 to 11 and digital inputs 1 to 10, and digital pulse counters 1 and 2.
CAN B 5.2 RS232. Direct serial communication to a computer. The PC-2000-W can be directly connected to a PC computer via a 9 pin D-sub connector to RS232-terminal on PC-2000-W. This connection is made as shown below and can be is used with the DripDrop configuration software PC-COM.
Below you see how a Westermo GDW-11 GSM modem is connected for GSM communication and SMS sending. Note that the digital output number 16 is used as modem control to restart the modem via the PC-2000-W. Below you see the connections between the PC-2000-W RS232 connectors and the terminals of the modem.
