Wireless Radio Modem
6661-1249-1
|
| Ideal
for SCADA 132-174 MHz 380-512 MHz 928-960
MHz |
|
FEATURES
- Remote Online Diagnostics to monitor
& maintain communications links Power,
Temperature, Voltage, Signal Strength,
Antenna/feedline condition, & data
decode performance transmitted online
- Up to 5 watts RF output in UHF, VHF
& 900 MHz
- Digital I/Os operate switches, relays
& sensors
- Programmable, transparent modem with
realtime data transfer
- CWID & CSMA
- Error-free data at up to 19200 bps over
air in a 25 kHz channel, 9600 pbs in a
12.5 kHz channel, 4800 bps in a 6.25 kHz
channel
- No dribble bits (extraneous data bits
to terminal device)
- DOX - data-activated transmit mode automatically
activates transmitter without RTS handshake
from terminal
- Supports CTS flow control where terminal
rate exceeds network rate
- Low power consumption modes - 3 ways
to reduce power consumption for solar
or battery powered remote sites: sleep,
suspend & variable output
- 132 - 174 MHz, 380 - 512 MHz, 928 -
960 MHz
- Optional DIN-rail mounting
