Early HIB modules (‘xxx’ is less than 200):
•
Support only local operation with MCNRCD. Skip all modem
references in this manual.
•
External module that connects to one of the PC’s COM ports.
•
Requires device driver LDVSLTA.SYS to be loaded by your PC’s
CONFIG.SYS file (see section 5).
All other HIB modules (‘xxx’ is 200 or greater):
•
Support both local and remote operation with MCNRCD.
•
External module that connects to one of the PC’s COM ports.
•
Requires device driver CTIHIB.SYS to be loaded by your PC’s
CONFIG.SYS file (see Section 5).
PCLTA Interface:
•
Support only local operation with MCNRCD. Skip all modem
references in this manual.
•
Internal interface card that plugs into an ISA bus slot in the PC.
•
Requires device driver LDVPCLTA.SYS to be loaded by your PC’s
CONFIG.SYS file (see Section 5).
1.2 System Hardware Requirements
Two components are required for the MCN RCD system.
1. Host Computer Interface Module (HIB) or PCLTA interface card
2. A PC to run the MCNRCD software with the following minimum
system configuration:
•
25 MHz 386 DX PC for 1 to 9 Comparator I/O Modules
or
50 MHz 486 DX PC for 10 to 20 Comparator I/O Modules
•
EGA or VGA adapter and monitor
•
2 MB RAM (if running from DOS)
•
2 MB free disk space for program and support files
•
5 to 100 MB additional free disk space if logging Status data
•
5 to 10 MB addtional free disk space if logging Errors
•
Microsoft or Logitech mouse (optional)
•
One open serial port (for HIB use)
•
One open full-size ISA slot (for PCLTA use)
•
MS-DOS 5.0 or higher
UART Requirements
For applications using the HIB module with a PC serial port, CTI Products
recommends that you have a 16550 type UART. This UART has a 16 byte FIFO
(First In First Out) buffer for the receiver that is used to prevent UART overrun
errors. If your COM port uses a 16450 or 8250 type UART, then you may not be
