Page 117: Changing Between Remote And Local Operation
5-16. Changing between Remote and Local Operation In addition to local mode (front panel operation) and remote, the 5820A Calibrator can be placed in a local lockout condition at any time by command of the controller. Combined, the local, remote, and lockout conditions yield four possible operating states described as follows.
Page 118: Interface Overview
Industries Association) standard RS-232-C. RS-232 is a serial binary data interchange operating from 300 to 9600 baud (selectable), and distances up to 50 feet. The 5820A Calibrator rear panel SERIAL 1 FROM HOST port is configured as DTE (Data Terminal Equipment) while the SERIAL 2 TO UUT is configured as DCE (Data Communications Equipment).
Page 119: Ieee-488 Interface Overview
For example, the command REMOTE could be sent as data over the IEEE-488 interface to place the 5820A Calibrator into remote, but it is not because the IEEE Standards call for the remote function to be sent to the device as the uniline message REN. This is also true for several other commands and functions, as shown below, with their equivalent RS-232 emulation.
Page 120: Using Commands
RS-232 Pass-Through Mode The RS-232 pass-through mode is used to pass commands from the PC to a UUT, but via the 5820A Calibrator. This configuration is used when the UUT has an RS-232 port. Commands are sent to the UUT by using the UUT_SEND command, returns use the UUT_RECV? query, and UUT_FLUSH clears the UUT receive buffer in the 5820A Calibrator.

In order to know what type of data to read in, refer to the first part of the entry under "Response" in the tables. The response is identified as one of the data types in Table 5-11.
Page 131: Checking 5820A Status
5-43. Serial Poll Status Byte (STB) The 5820A Calibrator sends the serial poll status byte (STB) when it responds to a serial poll. This byte is cleared (set to 0) when the power is turned on. The value of this byte at power-on is determined by the value of the service request enable register (SRE), which is saved in nonvolatile memory.

Page 133: Service Request (Srq) Line
Requesting service. The RQS bit is set to 1 whenever bits ESB, MAV, EAV, or ISCB change from 0 to 1 and are enabled (1) in the SRE. When RQS is 1, the 5820A asserts the SRQ control line on the IEEE-488 interface. You can do a serial poll to read this bit to see if the 5820A is the source of an SRQ.
Page 134: Programming The Stb And Sre
The Event Status Register is a two-byte register in which the higher eight bits are always 0, and the lower eight bits represent various conditions of the 5820A Calibrator. The ESR is cleared (set to 0) when the power is turned on, and every time it is read.

The controller reads it with a statement such as a BASIC INPUT statement, removing what it reads form the queue. If the queue is empty, the 5820A Calibrator does not respond to the INPUT statement from the controller. The Message Available (MAV) bit in the Serial Poll Status Byte is 1 if there is something in the output queue and 0 if the output queue is empty.
Page 139: Error Queue
Commands are processed one at a time as they are received. Some commands require a previous condition be set before the command will be accepted by the 5820A Calibrator. Using the following programming guidelines will insure that the output is programmed to the desired state.
