4-4.3 Auxiliary Parameters
The auxiliary alarm and fault inputs on the IIM must be enabled in order for them to display their status in
LaserNET.
1. Select Setup>Miscellaneous to open the Miscellaneous Parameters window.
2. In the Auxiliary Parameters box, check Alarm Enable or Fault Enable to activate these inputs.
3. Select <OK> to save the configuration.
4-5 ASSIGNING HART XL ADDRESSES
The IIM communicates with all HART XL Detectors over an RS-485 signalling line circuit. This circuit sup-
ports up to 127 unique addresses which are used to identify each HART XL Detector. There are hardware
and software addresses which must be set for correct operation of the communications network. The soft-
ware addresses are stored in the IIM, as explained in the next paragraph. The hardware address for each
HART XL Detector is set on the termination board. See the HART XL Installation, Operation and Mainte-
nance Manual (TM0042) for information on setting hardware addresses.
4-5.1 IIM (P/N 53836-K191 or 53836-K190)
The software addresses of all the Detectors installed on the RS-485 loop must be selected to communicate
with the IIM. Configure as follows:
1. Select Setup>Detectors from the main screen that is referred to in Figure 3-5 (not the Intelligent Inter-
face Module screen of Figure 4-1). The Detectors window opens, as shown in the next figure.
2. In the Addresses Installed section, either:
a. Place a check in the box for each installed address, or
b. LaserNET will register/deregister a range of Detectors with the Enter a Range of Detector Ad-
dresses function.
3. Enter the range of Detectors (ex., 3 to 15), choose either Register or Deregister and click <OK>.
4-6 DETECTOR CONNECTION MAP
The Detector Connection Map provides a troubleshooting aid for Style-4 and Style-6, RS-485 network wir-
ing. Detectors normally communicate on Channel One. If a network is broken, the Detectors after the break
will be reassigned to Channel Two for communications with the IIM. By viewing the Detector Connection
Map, the location of the wire break can be isolated.
