WIRING
This chapter describes wiring of the GP-IB interface module.
6.1

Wiring Procedures

The following shows how to connect and remove the GP-IB cable.
Connection
1.
Insert and connect the wired GP-IB cable horizontally to the slot of the GP-IB interface module.
2.
Fix the cable with GP-IB connector screws (M3.5) at two locations.
Removal
Loosen the GP-IB connector screws (M3.5) and pull out the GP-IB cable horizontally from the GP-IB interface module.
Precautions
• Up to two GP-IB cables can be connected in cascade to the GP-IB connector of GP-IB interface module.
• Avoid a load applied between the GP-IB connector of GP-IB interface module and the GP-IB cable.
• After wiring, attach the included GP-IB connector cover to the module, and then power on the system for operation. Starting
operation without the cover attached may result in electric shock.
• Tighten the GP-IB connector screws within the specified torque range.
Screw type
GP-IB connector screw (M3.5)
Depending on devices to be connected to the module or the installation environment, a communication error
may occur. If the communication error has occurred, take the following measures to improve noise immunity.
• Use a GP-IB cable where both the cable and entire connector have the shield structure.
• Install GP-IB cables 20cm or more away from the power cables, and 10cm or more away from the I/O signal
wires.
• When a device to be connected has a plug with the ground terminal, ground the terminal.
• Attach ferrite cores to the connector bases on the both ends of GP-IB cable. Use the ferrite core equivalent
to ZCAT3035-1330 manufactured by TDK Corporation. Use the ferrite core with the cable threaded through
it.
• Strip the jacket of GP-IB cable and expose the shield. Pinch the shield with an FG clamp, and ground and fix
it. For grounding the clamp, refer to the following.
