2.3.7 Termination Panel
The NGC8206 termination panel acts as a connection to the outside world (see
Figure 2-15
). It features transient protection, a voltage regulator for digital
controller, positive temperature co-efficient fuses (PTC) and many other
safeguards to protect the remainder of the system from electrical damage. All
outside communications and I/O are channeled through this board. It is designed
to be a low cost, field-replaceable maintenance solution and is designed to
operate on either 12 VDC or 24 VDC.
2.3.7.1 Features
• Transient protection
• EMI/RFI protection
• PTC fuses
• Voltage regulator for digital controller
• Dedicated local serial data interface (up to 115200 bps)
• 2 LED status indicators (software programmable)
• 1 Power monitor status indicator
• 1 5 VDC LED status indicator
• 2 DIs and 2 DOs connected to digital controller
• 2 remote serial ports (RS232/RS422/RS485 software selectable)
• Optional Ethernet interface with 3 LED status indicators
• Optional USB host and client interface
2.3.7.2 Local Interface
This local PC interface requires PCCU32 version 6.0 or higher, a laptop PC and a
MMI cable, either USB or serial RS-232. The software operates within the full
range of Windows 95, 98, 2000, NT and XP utilities. Maintenance functions can
be performed by personnel with little or no knowledge of gas chromatography; see
the online Help files for more information.
