Manual Overview
The Sencore Tech Tip #174 manual provides guidance on using the IB78 RS232 interface accessory for automated control of Sencore instruments. The IB78 connects to a computer via a serial port, allowing control of one or two instruments simultaneously, and supports remote testing through modems. The manual outlines the necessary equipment, including the Sencore instrument, IB78 interface, connection cables, and optional modems for remote testing. It details software options for control, recommending terminal programs like PROCOMM and CROSSTALK for ease of use. For more complex or frequently changing test routines, user-written or commercial instrument-control programs are suggested. The manual provides a step-by-step setup procedure for using the IB78 with a terminal program, including connecting cables, setting DIP switches, and selecting baud rates. Troubleshooting steps include checking for output activity and adjusting DIP switches based on screen readings. The manual also offers guidance on writing custom control programs using any familiar programming language, with a sample flowchart and GW-BASIC program example provided for reference.
Quick Issues Covered
- Diagnose continuous clicking: activate computer port.
- Test message failure: check IB78 connections and DIP switches.
- Use Ctrl-R for repeated readings; Ctrl-O for single reading.

Installation / Setup
The installation/setup highlights for using the IB78 RS232 Interface Accessory include connecting the IB78 to the Sencore instrument and the computer. Use a straight-through or null modem cable to connect the IB78 to the computer’s serial port. Set all DIP switches on the IB78 to the down position and select a baud rate, starting at 1200 baud or lower. Ensure the computer’s port is activated if continuous clicking is heard from the IB78. Apply power to the IB78 and Sencore instrument, and use the TEST MESSAGE button to verify setup. Adjust the IB78’s DIP switches based on legible readings from the computer screen.
Operation
The IB78 RS232 Interface Accessory allows for automated control of Sencore instruments via a computer’s serial port. To use the IB78, connect it to the Sencore instrument and the computer’s serial port using a suitable cable. Set the IB78’s DIP switches to the down position and select a baud rate, starting at 1200 baud. Turn on the computer and run terminal software at the same baud rate, then power on the IB78 and the Sencore instrument. If the IB78 clicks continuously, the computer port needs activation. Use the TEST MESSAGE button to verify the setup. Commands can be typed on the computer to control the instrument, and results will be displayed on the monitor. For repeated readings, send a Ctrl-R command; to return to single readings, send a Ctrl-O.

Overview
The Sencore Tech Tips 174 manual covers the use of the 1878 RS232 Interface Accessory designed for automated instrument control. This interface accessory enables seamless communication between test instruments and computers or other control systems via the RS232 serial protocol. It allows users to automate measurement processes, data collection, and instrument configuration, improving efficiency and accuracy in laboratory or production environments.
Main Features and Specifications
- RS232 serial communication interface compatible with standard COM ports
- Supports automated control of Sencore instruments using command protocols
- Compact, durable design for easy integration with existing test setups
- Compatible with a wide range of Sencore test equipment models
- Provides reliable data transfer speeds suitable for real-time instrument control
- Includes detailed command set documentation for programming and automation
Basic Usage and Operation Tips
To use the 1878 RS232 Interface Accessory, connect it securely to the instrument’s RS232 port and the controlling computer or device. Ensure that the correct COM port settings (baud rate, parity, data bits, stop bits) match the instrument’s requirements as specified in the manual. Use the provided command set to send instructions and query instrument status. It is recommended to test communication using simple commands before implementing complex automation scripts. Always power down the instrument before connecting or disconnecting the interface to avoid communication errors.
Troubleshooting and Maintenance
If communication issues arise, verify cable connections and ensure that the RS232 port settings on both devices are correctly configured. Check for any physical damage to the interface or cables. Resetting the instrument and restarting the controlling software can often resolve temporary glitches. Regularly inspect the interface accessory for dust or corrosion and clean connectors with appropriate electronic contact cleaner. Avoid exposing the accessory to moisture or extreme temperatures to maintain reliable operation.
Safety Reminder
Always follow proper safety procedures when working with electronic test equipment. Disconnect power sources before installing or removing the RS232 Interface Accessory. Avoid touching exposed connectors or circuitry to prevent electrical shock or damage. Use the accessory only as intended and refer to the full manual for detailed safety instructions.
