4 CHANNEL PROGRAMMING AND OPTION SELECTIONS
R50> read par parameter_name
Where "parameter_name" is one of the following:
Parameter Name Parameter Function Default Value Parameter Range
LOOP_GEN Generate a LOOP
potential (see 2.5)
Off Text: Off or On
PA_LOW_BAT Low Battery Alarm
Level (see 2.4)
20.0 (Volts) Floating Point Number
< 32.0
BAUD_RATE0 Port 0 Baud Rate 57600 (BPS) Decimal number:
300 - 115200
PARITY0 Port 0 Parity None Text: None, Even, or
Odd
FLOW_CONTR
OL
Port 0 Flow Control Off (“On” not
yet available)
Text: Off
Table 6: Some User Defined Parameters
Note that the parameter names have been shown in upper case, but they can be typed
in upper or lower case.
A parameter can be changed, or added, by typing
R50> set par parameter_name=parameter_value
As for parameter names, the parameter value can be Upper or Lower case if it is a text
value, as against a numeric value.
4.2 Setting Channel Parameters
One can read the data from an existing channel by entering the command:
R50> read chan chan_number
Where chan_number is a number from 0 to 99.
Entering new channel values, or modifying existing ones is possible from the
command line interface, but it is not recommended. It can be done by typing the
following at a command prompt:
R50> set chan chan_number parameter_list
Where chan_number is a number from 0 to 99.
The format of the parameter_list is quite complex. It has 14 fields. Each field can be
separated by a colon(:), comma(,), space, or tab.
For example set chan 0 25.0:35.0,100.0,120.0,0,5,2,0,5,2,10,11,0,3
Field1: Receive Frequency(in MHz). This is 25.0 MHz in the example.
