Raveon Technologies Corp.
K2
Disable LEDs
– When 1, LEDs are always off to
conserve power. When 0, LEDs work normally.
0, 1
0
K4
Disable DCD pin
– When 1, DCD pin is always
asserted, regardless whether carrier is present. When
0, DCD works normally.
0, 1
0
K7
Carrier Detect
– When 1, DCD pin operates with RF
carrier. When 0, DCD indicates presence of digital
data. Note K4 must be 0 for this setting to matter.
0, 1
0
MK
Address Mask
– Configures local and global address
space. Each digit may be a
0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,or F. In most
applications, this is kept at FFFF.
Range: 0000 - FFFF
FFFF
NB
Parity
– Selects parity format. Settings 0-4 transfer 8-
bits over antenna port and generate the parity bit on
the RF receiving side.
Range: 0 – 5
0 = none
1 = Odd
2 = Even
3 = Mark (1)
4 = Space (0)
0
NS
Stop Bits –
Selects the number of stop bits.
Range: 1-2
1
PE
Packet Error Display –
Shows statistics to compute
packet-error rate. Displays Packets Per Minute (PPM)
and a running total.
None (display PER)
1 = reset counters
2 = Stop PER display
None
MT
Protocol Type -
Selects the over-the-air protocol the
radio will use. All modems in the system must use
the same protocol type.
Range: 0 – 1
0 =
FireLine
(standard)
1 = SkyLine
(old Sonik)
0
R0
Symbol Peak Deviation
– Set the peak FM deviation
of the transmit symbols. Note: This can be a negative
number to invert the modulation.
Range: 0 – 1000
-100**
R1
Select CD pin output signal
– CD may be RF carrier
detect, or modem data detect.
Range : 0, 1
2 = Always assert CD
1 = Data CD
0 = RF CD
1
R2
Over-the-air bit rate
- This is the data rate the radio
uses to send data over the air.
All RF modems in
the network must use the same over-the-air baud
rate.
Range:
0 = 800 4 = 9600 4L
1 = 1200 5 = 9600 2L
2 = 2400 6 = 19200
3 = 4800 7 = 5142
3
R5
Preamble length
– The number of bytes to send
over-the-air in the pre-amble
Range: 1 - 255
4
**
(Varies based on
data rate and
radio type)
RT
Radio Type –
Select the type of radio module
installed within the modem. If this parameter is
chanted, you must fully recalibrate the modem.
Range: 1-9
2 = RV-M5-UC
(DM3473)
3 = RV-M6-UC
(DM3475)
2
**
R8
Frequency Offset.
Used to set the radio on the center of
the radio channel.
Range: -500 to +500
0
**
R9
Modulation Balance.
0-100
20
**
RA
Select RF CD output threshold
– This value is the
RSSI threshold where the carrier detect is asserted.
Note: To force CD always on, set this to 0, and R1 to
RF Carrier Detect.
Range : 0-999
300
**
RE
Default Configuration
– Restores radio module
parameters (R0 – RA registers) to factory default
configuration.
none
none
RS
RSSI
(Receive Signal Strength Indicator) – Returns
the signal level of last received packet.
none
Range: -120dBm to
-40dBm
none
RT
Radio Type
– Sets the type of radio module that is
integrated into the
FireLine
modem. If this is changed,
the modem must be re-calibrated.
1 = MURS
2 = DM3473
3 = DM3475
