1.6. GPIB (IEEE488) INTERFACE
All functions and outputs of the 4610M calibrator are fully programmable over the GPIB (IEEE488)
interface.
1.7. OUTPUT CONNECTIONS
Theoutputterminalcongurationisdesignedtomatchthemajorityofmultimeterinputconnections,
e.g. volts/ohms, low current and high current eliminating the need for lead changing during calibration.
All outputs are isolated when not in use and an L.E.D. indicator shows the active output(s).
2. COMMAND MODES
The 4610M comes with two command modes which can be selected via the front panel or via the
remote interface.
2.1. TRANSMILLE
The Transmille command mode provides access to all functions remotely in a structured programming
language
2.2. 55XX
The 55xx command mode provides an emulation/compatibility mode allowing the 4610M to be used
with existing software when replacing legacy products.
Note - some functions of the 4610M have no equivalent 55xx command and vice versa. The 55xx

Model 4610M Operation Manual

command mode should only be used for interoperability with existing software packages
2.3. CHANGING COMMAND MODE - FRONT PANEL
To change the command mode from the front panel, press the ‘Menu’ key from the home screen
Figure 1 – Calibrator Home Screen
FromtheMainMenu,select‘GeneralSettings’,andthenscrollto‘CongureCommandMode’
The current command mode is listed after the menu item.
Figure 2 – Calibrator Main Menu

TRANSMILLE LTD. V2.02 - August 2021 Page 8
Figure 3 – Calibrator Home Screen
Pressing the Select Key, the Enter key or selecting from the touch screen will show a menu allowing
the user to change the command mode.
Select the desired command mode, and press the Enter Key. The command mode has now been
updatedandthemenuwillreectthis.
2.4. CHANGING COMMAND MODE - REMOTE INTERFACE
To change the command mode, send the following command
2.4.1. ‘TRANSMILLE’ COMMAND MODE
SYSTEM:COMMANDS:MODE TRANSMILLE
2.4.2. ‘55XX’ COMMAND MODE
SYSTEM:COMMANDS:MODE 55XX
2.5. QUERYING COMMAND MODE - REMOTE INTERFACE
To query the current command mode, send the following command

Model 4610M Operation Manual
TRANSMILLE LTD. V2.02 - August 2021 Page 9
SYSTEM:COMMANDS:MODE?
A response of ‘TRANSMILLE’ indicates that the calibrator is in the ‘Transmille’ command mode
A response of ‘55XX’ indicates that the calibrator is in the ‘55xx’ command mode
3. TRANSMILLE COMMANDS
Warning: Risk of shock.
High voltages may be present on the output binding posts.
Ensure calibrator is in the STANDBY condition
before changing leads or connections.
For voltages greater than 30V AC RMS, 42V AC Peak or 60V DC, the binding posts must be in the
closed position.
ONLY 4mm banana connections should be used for outputs above these voltages.
Do not touch exposed metal on banana plugs, spade connections or bare
wires. These outputs may have lethal voltages present
Warning: Under no circumstances should any voltage
be connected to the calibrator outputs.
Although the output terminals are protected against voltage/current being
applied, repeated application of voltage/current may affect the performance and
reliability of the protection circuitry.
3.1. RESPONSE / ERROR CODES

*14 Output Overload
Table 1 – Transmille Error Code / Response Codes
All status/error responses are followed by <CR><LF>
3.2. PROGRAMMING COMMANDS OVERVIEW
The 4610M calibrators are controlled by a set of simple high level commands which can be used
either individually or as part of a command sequence.
The required terminator for the commands to be detected by the calibrator is a carriage return (ASCII
character 13) and should be the last character sent on a command line.
For Example:
{Command}{Data}<CR>
Where the command is represented as {Command}, the required value as {Data} and the carriage
return (ASCII character 13) is represented by <CR>
3.3. COMPOUND / CHAINED COMMANDS
To simplify remote commands, multiple commands can be sent in a single line of instructions. This
canreducethenumberoflinesrequiredinaprogramtoconguretheoutputofthecalibrator.
The separator ‘/’ (backslash) should be used between each command/data pair, as shown below.
An example of the use of this would be setting Range 1 (r1) for 200mV DC Voltage, with an output of
100mV (O100), followed by turning the output on (S0)
r1/O200/S0
These commands do not need extra delays, and can assist with writing complicated commands while
{Command} {Data}
{Terminator}

minimizing extra lines of code.
3.4. SETTING OUTPUT STATUS
The output status of the 4610M can be controlled with the following commands
Output Mode
Output OFF (i.e. Standby ON) S1
Output ON (i.e. Standby OFF) S0
The above commands have been included for software that communicates to legacy Transmille
products. Alternative commands are
Output Mode
Output OFF STBY
Output ON OPER
3.5. QUERYING OUTPUT STATUS
The output status of the 4610M can be queried with the following command
OPER?
Responses to this command are as follows
Output State Response
