Serial Interfacing Commands
DPORT
The DPORT is an object that responsible for data port
interface configurations like Bit Rate, Flow Control,
etc.
DPORT [Parameter Name] [Parameters List]
[/?]
Parameter
Name
Parameter List
RATE
0 – Maintenance Port baud rate, a default
setting 1 – 1200 baud
2 – 2400 baud
3 – 4800 baud
4 – 9600 baud
5 – 14400 baud
6 – 19200 baud
7 – 38400 baud
8 – 57600 baud
9 – 115200 baud, a default setting
BITS
Set number of bits in one byte (8 or 7) 8 is a
default setting
PARITY
0 – None, a default setting
1 – Odd
2 – Even
FLOW
0 – None, a default setting 1 – Not used
2 – HW (RTS/CTS)
MPORT
The MPORT is an object that responsible for main-
tenance serial port interface configurations such as
data rate and number of bits in a byte.
MPORT [Parameter Name] [Parameters List] [/?]
Parameter
Name
Parameter List
RATE
0 – Auto.
1 – 1200 baud
2 – 2400 baud
3 – 4800 baud
4 – 9600 baud
5 – 14400 baud
6 – 19200 baud
7 – 38400 baud
8 – 57600 baud
9 – 115200 baud, a default setting
Note:
JAVAD GNSSradio modem’s does not support data flow
and parity on the maintenance serial port.
Note:
MPORT operates using 8 bits in one byte fixed (not config-
urable).
Note:
The radio modem with none-dedicated maintenance se-
rial port must keep CTS line always active in MPORT mode (DP/
MP is low).
Special Commands
ALARM
The ALARM command is intended to set up the alarm
indication mode and alarm control lines’ behavior.
ALARM [Parameter Name] [Parameters List]
[/?]
Parameter
Name
Parameter List
TTL1
0– TTL_OUT1 = logic “1”
1– TTL_OUT1 = TTL_IN, received from re-
mote unit (default settings)
TTL2
0– TTL_OUT2 = logic “1”
1– TTL_OUT2 = TTL_IN2, received from
remote unit (default settings)
2 – TTL_OUT2 = SYNC Loss
3 – TTL_OUT2 = BER > BERTH or SYNC Loss
BERTH
1– BER Threshold >10 –3 (default threshold
level for BER)
2 – BER Threshold BER >10 –2
The Alarm LED must indicate the SYNC Loss and BER
exceeding the defined threshold.
Note:
The BERTH 1 / 2 is optional for TTL2 = 3 condition, other-
wise the BERT alarm is off
BOOT
The BOOT command is intended to reboot the unit
using selected user settings. Two options are avail-
able, to use the default user settings defined by deal-
er or to use the settings defined by end-user
BOOT [Parameter Name] [Parameters List]
[/?]
Parameter
Name
Parameter List
CFG
0 – selects the default user settings
1 – selects user modified settings
The BOOT command with no parameters selects the
user settings defined by the prior “parameterized”
BOOT commands.
HELP
The HELP command types the list of all available
commands:
HELP – Display this usage
BOOT – Reboot the unit
LINK – RF Link Operation Mode
DPORT – Data Port Configuration
MPORT
– Maintenance Port
