Installation steps

Module installation (universal)

Cut off all phase power supplies of GOT

Remove the cover plate of the GOT expansion unit

Insert the serial port module into the card slot

Tighten 2 installation screws with a torque of 0.36-0.48N · m

Apply anti-static stickers when not expanding; Keep the connector cover when expansion is required

Terminal block installation (GT15-RS4-TE only)

Insert the terminal socket into the module

Tighten the fixing screw with a torque of 0.20~0.25N · m

Shielded wire wiring (GT15-RS4-TE only)

Stripping length: 7mm

Connect the braided shielding layer using plate type crimping terminals

Wiring screw torque: 0.5~0.6N · m

Safety and wiring precautions

Installation Warning

Before installation/disassembly, all power sources must be cut off, otherwise there may be malfunctions or electric shock

Do not disassemble or modify modules

Release human static electricity before operation

Prevent debris, wires, and other foreign objects from entering the machine

Wiring specifications

Separate communication cables from main circuit/power lines * * ≥ 100mm * * to avoid interference

The cable must be fixed to prevent poor contact caused by pulling and pulling

The connector must be securely plugged in to ensure a reliable connection

Key questions and answers

Question 1: What are the core differences in interface and transmission distance among the three modules?

answer:

GT15-RS2-9P: RS-232 interface, D-Sub 9-pin (male), maximum distance of 15m.

GT15-RS4-9S: RS-422/485 interface, D-Sub 9-pin (female), maximum distance 1200m.

GT15-RS4-TE: RS-422/485 interface, terminal block wiring, maximum distance of 1200m, suitable for on-site wiring.

Question 2: What are the key operations and torque requirements that must be followed when installing a serial port module?

answer:

The installation/removal of GOT and PLC power must be completely cut off.

The torque of the screws for installing the module body is 0.36-0.48N · m.

GT15-RS4-TE terminal block fixed torque: 0.20~0.25N · m.

Terminal wiring torque: 0.5~0.6N · m.

Anti static stickers must be affixed when not cascading expansion.

Question 3: What is the function of the DIP switch between GT15-RS4-9S and TE? How to set up?

Answer: DIP switch is used for RS-422/485 terminal resistance switching:

Switches 1 and 2 are both ON: use the built-in 100 Ω terminal resistor.

Switches 1 and 2 are both OFF: Use an external terminal resistor.

This setting is only available for GT15-RS4-9S and GT15-RS4-TE, and GT15-RS2-9P does not have this switch.
