Description  

These communication modules provide Ethernet communications to the system bus compliant with IEEE802.3 

standard.  

Communications module, to connect a commercial transceiver  with AUI connector (15-pin female plug DIN 41652).

LED Displays  State   

Off  No supply voltage, module is isolated   

Green Power supply on, module identified and  ready to operate as configured.   

Orange Power supply on,  module identified and either:   

— normal transitory state after module  startup   

— configuration mode of Boot Loader   

Orange flashing Power supply on, module identified; module not connected to proper bus structure.   

Red Power supply on and either:  Page 10 June 2006   

— module not yet identified (normal for  short time during module startup)   

— error occurred during module test  Batt. 

Low   Off Sufficient buffer battery voltage.   

Orange Buffer battery not found or low (insufficient  voltage).
