INTRODUCTION
Micro Seven model CD15,
caller-ID receiver receives caller-ID FSK signals on telephone lines, and
converts to ASCII signals for outputs at RS232C interface to PC. It provides
decoding of caller-ID signals for both Bellcore (American) and ETS (European)
standards that are associated with ring signals. ASCII data output for RS232C
interface may be selected among raw data, control-character-stripped format, or
telephone number format. The telephone-number format outputs telephone numbers
only. Many RS232C data transfer handshake methods are provided including
hardware handshake (RTS/CTS), software handshake (XON/XOFF) or no handshake
modes. Standard accessories include AC/DC power adapter, RS232C interface
cable, and operator’s manual. Communication error is displayed If there is a
checksum error.
Micro Seven, Inc.
provides product warranty that is listed in specification section. Micro Seven
assumes no liability for loss of property, money, or human lives by application
of CD15, caller-ID receivers.

CD15
Control Register
The CD15 Control Register, one byte long, is read or
written by a special command string over RS232C interface. The CD15 Control
Register is a non-volatile memory, and it only needs to be written once. It
provides selection of caller-ID standards and ASCII output formats for PC.
When the bit 2 of CD15 control register is on,
Bellcore (North American standard) is selected. When it is off, ETS (European
standards) is selected. Major differences between Bellcore and ETS standards
are frequency shift frequencies. Bellcore standards are 1200 Hz for mark signal
and 2200 Hz for space signal, and ETS standards are 1300 Hz for mark signal and
2100 Hz for space signal.
When the bit 1 of CD15 is on, all the non-visible
characters such as control characters are replaced with a carriage return
(ASCII 13 decimal) and line feed (ASCII 10 decimal).
When the bit 0 of CD15 is on, telephone numbers are
output at RS232C interface.
CD15
Interface Register
CD15 Interface Register also resides in CD15, and it
provides selection of RS232C interface handshake method. Software handshake
using XON and XOFF is enabled all the time. The written command is M3D(n1)(n2),
and read command is R3D. A character "C" is output when write
operation into CD15 non-volatile memory is complete.
When all bits in CD15 Interface Register are off,
hardware handshake method is selected. The written command is M3D00. It sends
"C" after writing into non-volatile memory.
When bit 3 among bit 7-0 is on, hardware handshake
using RTS/CTS is disabled. The written command is M3D18 to select non-hardware
handshake mode and character echo method.
When bit 4 of CD15 interface register is on,
character (13 decimal) input to CD15 is required to transmit a next character
from CD15 to PC.
When bit 5 of CD15 interface register is on, 5
millisecond time delay is provided between transmission of characters.
