the Model 25 using the Tone Relay as a simul-select relay. When set to “0”, the tone relay is
used for its original purpose.
As soon as the last entry is made, the Model 25 saves the new settings to memory and returns
to the top of the General and
SEND Button question loop. You can either enter another
number to go through the loop again or just press
ENTER/RETURN on the PC keyboard to
return to the idle state.
SEND Button Setup
The four SEND buttons on the front of the Model 25 are used to send pages manually after
entering them from the keypad. These buttons need to configured before they can be used.
You will assign channel select relays to each button and set how the busy input for each
button is used.
Typing a single digit, 1 through 4, at the following prompt starts you through the SEND
Button question loop.
GENERAL OR SEND BUTTON SETUP(0-4)
PA1>1
After entering a single digit (1 through 4) in response to the last question, the following
prompt will appear. You will now assign control relays to be activated when the selected
SEND button is used. This question works the same way for the SEND buttons as it does for
most paging formats. Please see “Question 1 - Channel Select Relays” on page 72 for a
description.
CHANNEL SELECT RELAYS (000-255)
PA1;1>017
At the following prompt, the encoder expects a single-digit response (0 or 1) to indicate the
“Busy” polarity for the busy input associated with the Send button being programmed. The
default setting is “0”.
BUSY INPUT POLARITY (0=GND)
PA1;1>0
The two choices are: 0 = Input is BUSY when pulled LOW
1 = Input is BUSY when pulled HIGH
The LED associated with each Send button will be lit whenever the busy input is in the
“busy” condition. For more information on the busy input circuit, see Figure 7 on page 35.
At the following prompt, the encoder expects a single-digit response (0 or 1) to indicate
whether the encoder should observe or ignore the condition of the channel busy input
whenever the Send button is pressed. The default setting is “0”.
BUSY INPUT MONITOR? (1=YES)
PA1;1>0
