1-14.2 Remote Devices Using RS485 Bus to MCB
The ARIES NETLink system’s Main Controller Board includes an RS485 bus which can communicate
with the following remote devices:
• Remote LED Annunciator Module (R-LAM)
• Remote Display Control Module (RDCM)
• Model ATM-L Annunciator Driver Module
• Model ATM-R Relay Driver Module
• Fiber Optic Converter Module
The ARIES NETLink control unit supports the use of:
• up to 16 LED Annunciator Modules
• up to 15 Remote Display Control Modules
• up to 16 ATM-L or ATM-R Driver Modules (or any combination of these modules)
Note: The total number of remote devices cannot exceed 31 addresses. If an integrated LED
Annunciator is included in the ARIES NETLink front panel, the total number of remote
devices cannot exceed 30 addresses.
1-14.2.1 REMOTE LED ANNUNCIATOR MODULE
The Remote LED Annunciator Module (R-LAM) is an optional module which drives the display of
zone information and fits into the Remote Enclosure. The R-LAM provides 48 independently-
programmable microcontroller-controlled LEDs (red/yellow) with space available to place a label to
identify the event being annunciated. In addition, three system-level LED outputs are provided for
the following general conditions: Module Power, Trouble and Signal Silenced. Two system-level input
circuits for functional switches are reserved for Signal Silence and System Acknowledge/Self-Test
commands.
Note: The file LAM label template.doc is provided on the ARIES NETLink User Disk, P/N
06-220289-002, to assist with customized labeling. Text for the labels can be entered into
preset form fields (up to two lines of text per window). Cut the strips with a scissors and slide
them into the LAM from the top, retaining the top tab for easy removal.
Refer to Figure 1-12 for an illustration of the Remote LED Annunciator Module. Refer to Appendix
E for an illustration of the integrated LED Annunciator used in Canadian Applications.
