You can use a terminal block or
directly connect the cables
using a joint without problem.

(1) Basics
Item Description
Number of connected units
16 axes max. (The specific number varies depending on the operation
mode. Refer to 1.4, “Features of Gateway Unit.”)
Communication cable length Total cable length: 100 m max.
Communication cable
Double shielded twisted-pair cable (AWG22 --- Outer sheath diameter
1.35 to 1.60))
Recommended cable: HK-SB/20276 X L 2P X AWG22
by Taiyo Electric Wire & Cable
Terminal resistor 220
Ω 1/4 W
Caution
1. Connect the communication path to a bus and always connect a terminal resistor at the end. A
terminal resistor is not needed on the Gateway Unit end, as the unit has a built-in terminal resistor.
2. The customer must provide the communication cable. If the recommended cable is not used, make
sure the size of the cable to be used is AWG22.
(2) Linking PCON/ACON/SCON controllers via SIO communication
If the wiring receives tension or the IAI-recommended cable or equivalent is not used, it is
recommended that you use a terminal block or joint to perform the wiring without using the
connector. If the Gateway Unit connector receives tension, secure the cable nearby using a
mounting base, tie-band, etc.
*1 The terminal resistor (220
Ω,1/4 W) is supplied with the controller link cable.
