Description
These communication modules provide Ethernet communica
tions to the system bus compliant with IEEE802.3 standard.
Communications module, compliant with 10BaseT shielded
Twisted Pair (STP, cable category 3. 4 or 5 advanced)
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; mod
ule not connected to proper bus structure.
Red Power supply on and either:
— module not yet identified (normal for
short time during module startup)
— error occurred during module test
Batt. Low
EI 803F
Off Sufficient buffer battery voltage.
Orange Buffer battery not found or low (insufficient
voltage).
Front Panel Connections
RJ-45 female connector (shielded).There are two integrated
LEDs indicating the current communication status. The LEDs
are not labeled but can be identified by their color. The upper
yellow LED indicates the link state, the lower green LED indi
cates active communication.
LED 10BaseT link
off No active link. No communication possible.
static yellow Active link. Communication possible.
LED 10BaseT active
off No communication.
