Interfacing the XMP 2600

The serial interface

The Serial Interface is RS232 hardware interface with three types of operating modes: Monitor Mode, Remote Terminal Control Mode and Remote Computer Control Mode.

Operation

Pressing the terminal’s ENTER key while the Serial Interface is in Monitor Mode and the GPIB Interface is OFF will cause the Serial Interface to switch to the Remote Terminal Control Mode.

In addition to the Transmit and Receive lines, the interface implements the following hardware handshake lines:

DTR -	Data Terminal Ready.
CTS -	Clear To Send.
RTS -	Request To Send.
DCD -	Data Carrier Detected.

The interface has the following programmable parameters:

Baud Rate -	2400, 4800, 9600.
Xon/Xoff -	Yes, No.
Stop Bits -	1 or 2 depending on the Parity settings.
Parity -	Odd, Even, None.
Echo -	Yes, No.

The number of Start Bits is fixed at 1.

The Serial Interface Parameters are set in the SERIAL SET-UP MODE (see: User’s Guide).

The Serial Interface always uses “hardware handshake” (signals CTS and RTS). If you do not wish to utilize those signals, short pins 7 and 8 of the connecting cable, on the XMP’s side (see the User’s Guide for further details).

The selection of the ECHO parameter determines the Remote Control Mode of operation by changing some aspects of the behavior of the Serial Interface, as detailed below:

echo	Yes (terminal)	No (computer)

echo	echo each received character	no echo

prompt	'>'	{ACK}

SRQ string	'{bell}SRQ<'	'SRQ<'

terminators	{CR} echoed as {CR}{LF}	{CR}{LF} or {LF}

In the Computer Remote Control mode of operation, the XMP 2600 will respond to each command string with an ASCII {ACK} - 06 HEX.
