ALSTOM MCTI40N1AB0751G Voltage monitoring card

MECHANICAL SPECIFICATIONS The RSTL is contained in a printed circuit board assembly mounted internally in the ESS power supply unit. 4.7 OPERATING INSTRUCTIONS The following subsections describe the operation of the RSTL in detail.After the command string is processed the contents of the output buffer are transmitted over the RS232 lines. At any time the output buffer may be read using the GPIB. All messages are terminated with a carriage-return and a linefeed character.

GPIB AND RS232 INTERFACES 

The RSTL interfaces to a computer using either GPIB or RS232 data transfer methods. See IEEE Std 488.1 for mechanical details of the GPIB connection. The RS232 port follows the 9-pin IBM AT serial port standard for DCE devices. The RSTL accepts a command string from either port and processes that string. If any messages are generated by the command string (e.g. Voltage Readback) the message is placed in an output buffer.
