D
Numeric character that indicates whether the carrier detect circuit in the paging encoder is currently
detecting a carrier signal or not. Valid values are:
0 =
Carrier Signal Not Detected
1 =
Carrier Signal Detected
Note:
The carrier detect signal status is passed to the PC whether or not the paging encoder has been programmed to
avoid transmitting when a carrier signal has been detected (see Programming Command below).
C
A single numeric value used to indicate the
On/Off
state of the Carrier Detect mode. The numeric
character is followed by a comma.
Valid values
(C)
are:
0 =
Off
1 =
On
II
A two hexadecimal digit value that is reserved for future use.
<EOT>
(Hex code 04) is used to mark the end of a message
<NAK>
(Hex code 15) is used to indicate non-acknowledgment of a command from the host system.
<EE>
Two numeric characters that indicate the particular error that caused no acknowledgment of a command
from the host system.
The possible error values are:
01 =
Invalid Message Type
.
Indicates a message type other than A, N, 1-4 was transmitted.
02 =
Invalid Data Rate.
Indicates a data rate other than 5, 1, or 2 was transmitted.
03 =
Invalid Capcode.
Indicates an invalid capcode was transmitted. Invalid capcodes are: 0-7,
2007664-2007671, 2045056-2045063, .
04 =
Input Buffer Overflow.
Indicates the serial data input buffer in the paging encoder has overflowed.
This condition would likely be caused by the host system not recognizing the CTS signal.
05 =
Paging Buffer Overflow.
Indicates the encoded paging message output buffer in the paging
encoder has overflowed. This condition would likely be caused by excessive carrier signal
detection while the Carrier Detect mode was enabled.
06 =
Invalid Status/Setup Command.
Indicates that the command was recognized as a Status or
Setup command but the entire command string was not fully interpreted by the paging encoder.
07 =
EEPROM Write Error.
Indicates an internal system error in the paging encoder with regard to the
proper storage of configuration information. This condition would likely indicate that paging encoder
repair is required.
08 =
Invalid Command Format.
Indicates that the command was not fully recognized as a valid paging
encoder command.
