16 MB RAM
Rechargeable (recharges whenever the brain has power). 5-year life when power is
off. (Models manufactured before August 2007 have user-replaceable batteries.
See original user guide for details or contact Product Support.)
0 to 60 °C
-40 to 85 °C
0–95% humidity, non-condensing
IEEE 802.3 network, 10Base-T and 100Base-TX. Automatic MDC/MDI-X crossover
(Ethernet crossover cable not required for direct connection to PC). Two switched
interfaces, allowing multi-drop (daisy-chain) or standard star network configuration.
100 meters with Category 5 or superior UTP
For 100 Mbps at this distance, use Category 5 or superior solid UTP.
RS-485, 2- or 4-wire, twisted pair(s), with shield
300 baud to 230.4 Kbaud
32 stations maximum between repeaters; up to 3000 ft (914 m) between repeaters
–
5.2 VDC at 750 mA maximum (does not include module power requirements)
Serial port
On a serial brain, the port is RS-485, either
2-wire or 4-wire. Baud rate, termination,
and address are set using the switches on
the brain’ s top cover.
See form #1690, the SNAP PAC Brains User’ s
Guide, for serial cable recommendations
and wiring.
NOTE: IRQ connections and LED are reserved
for future use.
