PMC adapter provides four independent RS232s
19 April 2006
Computer/Embedded Technology
Concurrent Technologies has released a four-channel asynchronous serial communications PMC adapter suitable for CompactPCI or VME platforms.
The CC PMC/RS1 is a single-width PMC adapter that provides four independent RS232 channels (plus an IEEE1284 parallel port) or four independent RS422/RS485 channels. Front and rear I/O is available for both interface types. The RS232 datarates are up to 230 Kbps full duplex and the RS422/RS485 datarates are up to 4 Mbps, where the maximum power consumption is 2,5 and 5,0 W, respectively.
The CC PMC/RS1 is an upgrade to Concurrent Technologies' legacy serial PMC adapters, the CC PMC/232 and the CC PMC/422. The CC PMC/RS1 uses the Oxford Semiconductor OXmPCI954 quad UART chip and is designed to handle high-speed serial datarates. The OXmPCI954 integrates a PCI interface, four high-performance UART channels compatible with the industry-standard 16C550, and a bidirectional IEEE1284 parallel port supporting SPP (standard parallel port), EPP (enhanced parallel port) and ECP (enhanced capability port) protocols. The CC PMC/RS1 PCI interface supports a 32 bit 33 MHz PCIbus and is compatible with 3,3 and 5 V PCI signalling.
There are two build versions of the CC PMC/RS1 available.
The CC PMC/RS1-25 provides front panel access to four RS232 serial channels and an IEEE1284 parallel port via a 68-pin SCSI-3 connector and rear panel access via the PMC's P4 connector. The CC PMC/RS1-50 provides front panel access to four RS422/RS485 serial channels via a 68-pin SCSI-3 connector and rear panel access via the PMC's P4 connector.
Front panel cables are available to convert from the 68-pin connector to standard 9- or 25-way D-type connectors.
The CC PMC/RS1 can be used with any board level product featuring a standard PMC host interface, including Concurrent Technologies' CompactPCI or VME-based PMC host-board processors.
For ease of integration, many operating systems are supported including Linux, Windows 2000, Windows XP, Windows XP Embedded, QNX, VxWorks and Solaris.
