3.3.2 CHANNEL EXTENDER Cards

CHANNEL EXTENDER cards are used to extend the NETWORK functionality of the

NETWORK / CONTROL card, providing network access to the DEVICE ports in the system.

The Channel Extenders provide additional circuits allowing more simultaneous network

sessions, up to the system capacity of 16 device sessions. Channel Extenders are installed in

slots B, C, D, and slot E, replacing the NETWORK cards and the TERMINAL cards in a 3200

system.

The SCS3230 is normally configured with four CHANNEL EXTENDERS, but may have any

combination of CHANNEL EXTENDER cards and TERMINAL cards, as required for your

application.

Note: At least one Channel Extender card is required if any DEVICE access is required using

your IP Network.

CHANNEL EXTENDER cards connect to the NETWORK / CONTROL card using a short RJ45

cable. Each CHANNEL EXTENDER provides up to four (4) simultaneous sessions for DEVICE

port access over the IP Network connection.

3.3.3 TERMINAL Cards

The TERMINAL card provides a point of connection for a conventional RS-232 terminal or a

computer running a terminal emulation program. Users connected through a TERMINAL card

may connect to any of the device cards in the system, provided that their user profile has

access rights for the port. There are four ports per terminal card. Each port‘s parameters are set

up independently from the other ports. All parameters are set up through the system

administrator port. There is no access to the administration functions through the terminal card.

The SCS3230 may have up to 3 Terminal cards, depending on system requirements. In some

applications, the existing Terminal Card may be required for local serial connection to one of the

Device Ports. The existing Terminal Card is compatible and may be used, however the use of

each Terminal Card(s) reduces the number of simultaneous Network connections (by 4

sessions) that may be made over the new 10/100 Network port on the Network Control Card.

The 3200 Terminal cards offer configurable port parameters (baud rate, DTE/DCE, etc.), unlike

the fixed parameters of the TERM (Console) port on the NETWORK / CONTROL card.

The SCS3230 requires version 4.00 (or higher) of the Terminal Card binary firmware (fterm.bin).

This is not specific to 3230, and has been available for some time. Firmware updates are

downloadable from the Lightwave FTP site (ftp://ftp.lightwavecom.com).

3.3.4 3200 Network Cards

The earlier 3200 Network card (10baseT) is not supported by the 3230 Network / Control Card.

It will not function if installed.
