TPMC683

TPMC683 32 Port RS-422/485 I/O Module

32 digital differential I/O lines using EIA-422 / EIA-485 compatible ESD protected transceiver. Each line of the TPMC683 PMC module can be individually configured as differential input or differential output. The differential receivers are always enabled, allows determining the state of the I/O line at any time. This can be used as read back function for lines configured as outputs.

All 32 input lines can generate an interrupt. Each input interrupt can individually be enabled and cleared. The signal edge handling is programmable. For interrupt source detection, the status of each line can be read from interrupt status registers.

The TPMC683 provides front panel I/O via a HD68 SCSI-3 type connector and rear panel I/O via P14.

A wide range of drivers is available: Linux, QNX, VxWorks and Windows. All drivers - except the Windows drivers - are supplied as C source code.
