IPE2500A and IPE2500A-MLS Paging Encoder/Desktop Controller Operation
35 03/12
Frequency Changing
Frequency changing allows the PC to direct the IPE2500A to change the current transmit frequency to a
newly specified transmit frequency such as F12.
Byte Value Description
0 5 ‘5’ (0x35): Always for Frequency Change
1 Y1 First ASCII digit of frequency number to select (most significant digit)
2 Y2 Second ASCII digit of frequency number to select (least significant digit)
3–9 X Don’t care/Unused
Example:
To change the current frequency to F12:
PC to IPE2500A: ‘^’, <CR>
IPE2500A to PC: ‘0’, ‘1’, ‘8’ (Response)
PC to IPE2500A: ‘5’, ‘1’, ‘2’, ‘~’ (Frequency changed to F12)
IPE2500A to PC: ‘~’ (Acknowledge that frequency change is complete)
Custom Tones
Custom tones allow the PC to direct the IPE2500A to initiate a transmission and generate a specified tone
frequency. The unit remains keyed to allow additional tones to be generated until the PC directs the
IPE2500A to cease transmission.
Byte Value Description
0 4 ‘4’ (0x34): Always for Custom Tones
1 0 or 1 ‘0’ (0x30): Cease Transmission
‘1’ (0x31): Initiate Transmission (must remain ‘1’on subsequent tone generations)
2–3 MSW Most significant word of ASCII frequency in hex
4–5 LSW Least significant word of ASCII frequency in hex
6–9 X Don’t care/Unused
