•
2MB Flash, expandable to 4MB.
•
4K bits serial EEPROM.
•
Optional on-board 14.4 KBPS PPP modem.
•
Controls I/O modules on “I/O BUS” via 5-position male connector located on the
right side of the case. Supports either RS-485 (Andover LON) @ 39k baud or
FTT-10 (LONMark) @ 78k baud communication interfaces.
•
4 Communications ports (excluding I/O BUS):
•
COMM1 – RS-232 / RS-485 Infinet network or RS-232
•
COMM2 – RS-485 Infinet network
•
COMM3 – RS-232 / Modem Internal Modem or RS-232
•
COMM4 – RS-485 Infinet network
•
During UPS operation, the CPU can turn off the I/O power to extend battery life.
Also, the CPU can go into low-power mode in which only the DRAM and Real
Time Clock are powered.
