PMC adapter provides four independent
RS232s
A new four-channel asynchronous serial communications PMC adapter is suitable for CompactPCI or VME platforms.
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

The PP PMC/002 is designed to provide a cost effective and flexible approach to implementing standard and custom I/O requirements using industry standard PMC modules in CompactPCI systems.
Front and rear I/O is available for both interface types.
The RS232 datarates are up to 230Kbit/s full duplex and the RS422/RS485 datarates are up to 4Mbit/s, where the maximum power consumption is 2.5 and 5.0W, 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 32bit 33MHz PCIbus and is compatible with 3.3 and 5V 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 (Tx, Rx, RTS, CTS, DTR, DCD) 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 (Tx, Rx, RTS, CTS, DTR, DSR, DCD, RI) 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.
As stated earlier, these interfaces are compatible with the Concurrent Technologies' legacy serial PMC adapters, the CC PMC/232 and the CC PMC/422.
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 of today's leading operating systems are supported including Linux, Windows 2000, Windows XP, Windows XP Embedded, QNX, VxWorks and Solaris.
