Page 3: Introduction
RS-485 is optimized for ‘Multi-Drop’ or ‘Party-line’ operations selecting data from multiple peripherals (as many as 31 devices can be connected on an RS-485 bus). The C4-104.ULTRA is optimized for RS-485 with automatic driver enable, and automatic suppression of RS-485 ‘Echo’ as options, further simplifying integration. -
Page 4: Before You Get Started
Before You Get Started What’s Included The C4-104.ULTRA is shipped with the following items. If any of these items is missing or damaged, contact the supplier. C4-104.ULTRA Serial I/O Adapter Advisory Conventions Warning The highest level of importance used to stress a condition where damage could result to the product, or the user could suffer serious injury. -
Page 5: Card Setup
Card Setup The C4-104.ULTRA contains two DIP-Switches and a jumper strap for each port, which must be set for proper operation. Address Selection Each port on the C4-104.ULTRA occupies sixteen consecutive I/O locations. A DIP-switch is used to set the base address for these locations. The following table shows the addressing options available. If different address options are required, please contact Sealevel Systems Technical Support about a custom PAL option. - Page 6 Header E1 (IRQ Selection) The C4-104.ULTRA has a single interrupt selection jumper for all four of the ports, which should be set prior to use, if an interrupt is required by your application software. Consult the user manual for the application software being used to determine the proper setting.
- Page 7 921.6K bps Programmable Features Each of the ports on the C4-104.ULTRA can be individually configured as an RS-232, RS-422, or RS-485 interface. This is a software selectable feature. Electrical Interface selection (RS-232/422/485), RS- 422/485 termination, and RS-485 ‘Echo’ control are selected via the ‘Control’ port (Base + 8). If the Sealevel Software Windows drivers are used, this is accomplished as a function of the Device Manager.
- Page 8 Typically, each end of the RS-485 bus must have line-terminating resistors (RS-422 terminates at the receive end only). One of the unique features of the C4-104.ULTRA is its ability to select this termination via a control word in the control port. It is completely software selectable, thus reducing the complexity of cabling typically found in RS-485 implementations.
