4.3.2. The CRC Function
The CRC (Cyclic Redundancy Check) function appends a two byte check sum to each response
to Command ^B01 (Release Data). After data is received, CRC values can be used to check the
integrity of the record or block. The CRC function is an option in either of the ASCII Output
Modes, and is always enabled in the Binary Block Mode.
Communication parameters for the PollCat III Port used to access the Command Mode
(Computer Port and/or Modem Port), must be set at 8 bits, no parity. To enable or disable the
CRC function, enter the Command Mode and proceed as follows.
1. To enable the CRC Function, type ^B63,2 [Enter].
2. To disable this function (Default), type ^B63,1 [Enter].
4.3.3. The Line I.D. Function
When data is released, the Line I.D. function will insert a six digit I.D. number at the
beginning of each record. This number can be used to ensure that call records have been
correctly received. To enable or disable this function, enter the Command Mode and proceed
as follows:
1. To enable the Line I.D. function, type ^B59,2 [Enter].
2. To disable this function (Default), type ^B59,1 [Enter].
4.3.4. Select Compression Mode
Compression Mode shortens transmission time by releasing data in space compressed format.
To select the Compression Mode, enter the Command Mode and proceed as follows:
1. To release data in decompressed format (Default), type ^B53,2 [Enter].
2. To release data in compressed format, type ^B53,1 [Enter].
4.3.5. Release Data with Command ^B02
Command ^B54 determines how the PollCat III will react when the ^B01 command is invoked
to release call data.
When Command ^B01,n is invoked in the default state (^B54,1), the first record or block will
be released without the need to issue a ^B02 command. After the first record or block has been
released, PollCat III will require a ^B02 in order to release any subsequent records or blocks.
When ^B54,2 is active, and Command ^B01,n is issued, a ^B02 command will be required in
order to release the first record or block. Command ^B02 will also be required in order to
release any subsequent records or blocks. To configure this function, enter the Command
Mode and proceed as follows:
1. To wait for a ^B02 command before releasing the first record or block, type ^B54,2
[Enter].
2. To release the first record or block without the need to enter a ^B02 command (Default),
type ^B54,1 [Enter].
