SERIAL INTERFACE MODULE (GSA) FOR INTELLIGENT SYSTEM INTERFACING

Four general purpose serial interfaces

RS422 or RS485 type electrical standards supported

Asynchronous and synchronous protocols supported

For inplementation of application specific serial links

The GSA module is capable of interfacing up to four intelligent systems. The module is based on the Motorola MC68360 QUICC processor, and it has a pSOS real-time kernel.

The module’s QUICC processor supports four high-speed serial channels which can be used for application purposes. TCNgateway facilities are available for these interfaces.

A set of standard protocols are available for the interfaces. The serial interface protocols can also be implemented as a part of the project work or the user can write custom protocols by means of Ctasks on top of the module’s real-time kernel.

Properties and Interfaces

Processor and memory. 32 bit 25 MHz MC68360 QUICC processor with up to 4 Mbytes Flash EEPROM and up to 4 Mbytes SRAM located on the QCP piggy-pack module. BDM-interface for emulation.

VMEbus interface. Slave VMEbus (A24/D16) interface.

Serial channels. Four programmable isolated asynchronous or bit-synchronous SCC-channels for application purposes.

Software interface with the TCN gateway. PST interface. This interface is for user Event log operations, software downloading

and application development purposes.
