12.5 Showing Real Time in Dynamic PS
It’s possible to show real time in Dynamic PS in mode 0 and 2. To show the time, the text must contain %HH-MM%%
string and this string must exactly fill the 8-character window. Then on each string occurrence place the real time will
be displayed. The separator between hours and minutes is user selectable.
12.6 Addressing
12.6.1 Why use addressing?
If only one RDS encoder unit is connected to the RS-232 COM port, there is no need to use the addressing feature
and you should simply ignore it.
If more units are connected to one COM port channel and the user needs to control the units independently, then the
addressing feature is very useful. You can communicate only with selected unit(s). A good example of this
application is remote control via satellite when one satellite uplink is used to distribute RDS control commands to
many transmitter sites and each transmitter may then carry different RDS data.
12.6.2 What does the addressing feature allow?
It allows connecting multiple units to one COM port and then controlling them independently, up to 255 unique
addresses are available. (Unit addresses 0 and 255 are equivalent.) Units with addresses in the range 1-254 will
no longer respond to general commands on the COM port. They can then only be controlled if selected by the
SEL command. For address range 1-254 the unit is selected for up to 20 minutes (selection timeout). For address
0 and 255 the unit is selected for an unlimited time.
If a unit is selected, other units are unselected immediately. Unselected units "listen" on the port for selection of their
address. Other commands are ignored.
The addressing feature is controlled by ADR and SEL commands or simply by Windows control software.
Note: If only one unit is connected to the port and has address 0 or 255 (default), there is no need to use the
SEL command and addressing feature needn’t to be taken into consideration
12.7 Expansion IIC Bus
The expansion IIC bus provided on connector J3 allows connect varied devices respecting the customer needs.
For example LCD display, digital potentiometer etc.
12.8 Real-Time Backup
A battery-powered RTC circuit provides real-time backup for case of mains power supply interruption or switch off.
Use TIME and DATE commands to set the time and date information or simply use the Windows control software.
12.9 Firmware Upgrade
The RDS encoder has a firmware upgrade capability. This allows easily implementing of new features in future.
When a new firmware version is released, special simple Windows application provides the firmware upgrade. The
firmware upgrades are provided at no costs. Please refer to the website for more information.
