RF300E/RF310E 153
S-Register: S92
Usage: S92=n; S92?; S92.b=n; S92.?
b=bit number, n=value
Function: Channel ID Information Element Octet 3 Settings
Unit: Decimal ASCII code
Range: bit 6—Interface ID present
bit 5—Interface Type
bit 4—0 spare
bit 3—Preferred/Exclusive
0 = Preferred
1 = Exclusive
bit 2—D-channel Indicator
bit 1—Info. Channel Selection
bit 0—Info. Channel Selection
00 = No Channel
01 = B1 Channel
10 = B2 Channel
11 = Any Channel
Default: 3 (00000011 binary) Preferred, Any Channel
Description: S92 allows octet 3 of the Channel Identification Information Element to be modified,
but currently only bits 3,1, and 0 can be modified. Bit 3 controls the Preferred/
Exclusive setting. Bits 1 and 0 control the Information Channel Selection. To force a
call on B2, set bit 3 to 1 (S92.3=1), set bit 1 to 1 (S92.1=1), and set bit 0 to 0
(S92.0=0)—or simply set S92=10 which does the same as setting each bit
individually. By default, the Channel ID is preferred/any channel.
S-Register: S93
Usage: S93=n; S93?
Function: Blacklisting
Unit: Decimal ASCII code
Range: n=0 (Disable),
n=1 (Enable)
Default: 1 (Enabled)
Description: S93 determines whether blacklisting is enabled or disabled. Blacklisting currently
only affects the NET3 and INS64 switch types. For Australia (NET3) and Japan
(INS64), blacklisting is required. For Europe (NET3), blacklisting may be disabled if
it becomes a problem by setting S93=0. By default, blacklisting is enabled for NET 3
and INS64, however, it should be rare that blacklisting occurs.
S-Register: S94
Usage: S94=n; S94?
Function: Minimum Buffer Space After Trigger
Unit: 10 bytes
Range: n=0-255 (0-2550 bytes)
Default: 10 (100 bytes)
Description: When S95 and/or S96 are set to continuously store information until a specific event
(or trigger) occurs, then once that trigger occurs a minimum number of bytes will be
freed (if needed) in the respective buffer. S94 sets the minimum number of bytes
requested to be freed in the respective buffer once a trigger has occurred. By default
a minimum of 100 bytes are freed in the respective buffer.
S-Register: S95
Usage: S95=n; S95?
Function: Logging Buffer Functionality
Unit: Decimal ASCII code
Range: n=0—Stop when full,
n=1—Wrap continuously,
