Page 8: Getting Technical Support
IDAN Multi Serial Port Cable (4 ports) (To connect all 8 ports, purchase two IDAN-XKCM33s) In addition to the above ordering options, RTD can also provide the CM17320HR with various customizations (e.g. conformal coating, custom connectors, soldered jumpers, etc). Contact RTD’s sales department (sales@rtd.com) for more information. -
Page 9: Hardware Description
Supported Baud Rates When using the standard 14.7456 MHz oscillator, the CM17320HR supports the standard baud rates of PC serial port (e.g. 2400, 9600, 19.2k, etc). The CM17320HR can also support non- standard baud rates via a User Oscillator. The baud rate of a serial port is set by dividing the input clock (typically 14.7546MHz). For the Exar XR17D158, there are two dividers to specify. - Page 10 This can be done with a User Oscillator. A user-specified oscillator can be installed in U3. The max frequency for the user oscillator is 50 MHz and the max baud rate for the chip is 6.25 Mbps. Alternatively, RTD can preinstall several common oscillator frequencies.

PCI Board Selector, SW1 The CM17320HR uses a rotary switch to select the PCI slot. Before you can use this module you have to set the PCI board selector switch. The procedure is if this module is the first module from the CPU module select ’0,’... -
Page 17: Board Installation
Board Installation Installing the Hardware The CM17320HR can be installed into a PC/104-Plus or PCI-104 stack. It can be located almost anywhere in the stack, above or below the CPU as long as all PCI bus constraints are met. Static Precautions... - Page 18 Note: Before installing any drivers, it is recommended that you visit the RTD web site to check for a newer version. The actual procedure for installing the software will depend on the operating system. Consult the documentation provided with the software for installation instructions.

Page 19: Software Programming
These applications may have compatibility issues with the Exar PCI UART. Base Address and Register Mapping The CM17320HR exposes all of the registers available on the Exar XR17D158. The register set of the XR17D158 mimics the standard 16C550 UART register map. However, the XR17D158 contains some additional registers not found in a typical ISA-based UART. -
Page 20: Interrupts
Interrupts Since the CM17320HR is a PCI device, it is capable of sharing interrupts with other PCI devices. Interrupt sharing is a normal part of PCI operation, and a required part of the PCI specification. Note that any Interrupt Service Routines developed for the CM17320HR must be properly written to support interrupt sharing. -
