7.3.2 Interface Functions

The CPC 6000 responds to the following IEEE-488 interface functions:

SRQ Service Request: A service request is asserted whenever an error is encountered. When

the bus controller issues a serial poll the error will be cleared. If the host IEEE board in

cludes automatic serial polling capability, turn this feature off in order to view all errors (see

ERROR? command).

LLO Local Lockout: The front panel keyboard of the CPC 6000 may be locked by sending LLO

or the command LOCK ON.

GET Group Execute Trigger: When this message is received, the CPC 6000 will save the current

readings until the next time it is addressed as a talker.

GTL Go To Local: A GTL message will cause the CPC 6000 return to local operation and unlock

the keyboard.

DCL Device Clear: When this message is received, the CPC 6000 will clear all errors and buffers

and remain in the REMOTE mode.

SDC Selected Device Clear: The effect is the same as DCL.

EOI End or Identify: May be used as a command or query terminator in the place of, or concur-

rent with, a terminating linefeed.

7.4 RS-232 Serial Communication

The serial communication port allows the CPC 6000 to communicate in RS-232 format with comput

ers, terminals, PDAs, or similar hosts.

7.4.1 Cable Requirements

RS-232 communications are transmitted over a three conductor, shielded cable terminated in a stan

dard DB9S connector on the instrument end, and usually the same connector on the host end. Figure

7.4.1 illustrates the proper pin-outs. Notice that each pin 2 is connected to pin 3 on the opposite end.

This configuration is commonly referred to as a 9-pin null modem cable.
