6.0 COMMUNICATIONS
6.1
General
Serial communication may be established between the 17CA3000 Chloralert™ Plus and a host
communications device. Possible serial communications host devices are Microsoft Windows
NT- based PCs running either of the following De Nora Water Technologies products:
•
53PW6000 Micro-PWC
TM
•
53SU6000 Micro-DCI
TM
Communication Services
Thirty-two addressable instruments (using instrument addresses 0-31) can be connected to a datalink
for information transfer to or from a host. All transactions are initiated by the host.
This section provides information to configure the communications interface. A description of the datalink
protocol message field definitions, a summary table of the instrument memory address scheme, and
a mnemonic-datapoint cross reference table unit-tag atom transfers.
Information available via the optional digital communication protocols is shown below:
•
ALL SETUP
parameters
•
Status
parameters such as gas concentration and battery status
All of the above information may also be shown on the display. It is not possible to access the event
queues using the databank.
6.2
Interconnections
Serial communication capability is optional and requires interconnecting wiring. In addition to the
diagrams below, refer to Figures 2-3 and 2-4 of this instruction bulletin. This information applies to
only those instruments with the optional RS-232 or RS-485 modules.
Figure 6-1 illustrates the optional RS-232 or RS-485 module used in the Chloralert Plus. The module
is installed in the appropriate location on the main PCB assembly (refer to Figure 2-3). The module is
socket mounted and is secured to the circuit board assembly with a screw. Figure 6-1 also shows the
module and is secured to the circuit board assembly with a screw. Figure 6-1 also shows the module
signal plug, which is keyed to prevent inverted insertion in its socket. As shown in Figure 6-1 (e.g.,
insert screwdriver at base), the lug adjusting screws are accessed at the bottom of the plug.
