Settings Description
Station Address of this
Interface:
The address that Unite CM has on the ESPA bus.
Default: 1.
External Station Address: The address that the remote device has on the ESPA
bus. Default: 2.
This Interface is the Control
Station:
Select whether Unite CM is the ESPA bus master.
Default: Yes.
Extra Carriage Return: Select whether to add an extra carriage return.
Default: No.
Polling During Idle Periods: Only used if the device is the control station.
The remote device has to be polled before it is
allowed to send data. Normally polling is done
continuously, but some devices cannot handle this.
If the remote device cannot handle it, set this option
to 'No'. Do not set this parameter to 'No' if the
“Status Mode” parameter is set to “Automatic”.
Default: Yes.
Status Mode: Most ESPA devices will reply with status messages
automatically. If the remote device does not
automatically send status messages, this parameter
should be set to “Request”. Do not set this
parameter to “Automatic” if “Polling During Idle
Periods” is set to “No”. Default: Automatic.
Delay Period for Retry:
(0 - 10 000 ms)
If the remote device cannot accept a message, there
is a delay period before retrying to transmit the
message. Default: 1 000 ms.
Max. Number of Active Pagings: Sets the maximum number of pagings that will be
put in the queue of the remote device. Some devices
may not be able to handle too many pagings
simultaneously which might result in lost status
responses. Default: 1.
Settings Description
Number of digits in Call
Address:
The number of digits that a pager call number has in
the ESPA system. Default: 3.
Usage of Number of Digits: Select what to do when the destination address of a
message does not comply with the “Number of digits
in Call Address” parameter. Default: “Log warning”.
Number of Transmissions: The number of transmissions is a value that is
transferred to the remote ESPA device. It indicates
how many times the remote device will transmit the
message to its destination. Default: 2.
