Application Precautions 5 • When the 24-VDC output (service power supply to the PC) is overloaded or short-circuited, the voltage may drop and result in the outputs being turned OFF. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system. ! WARNING Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so may result in malfunction, fire, or electric shock. 4 Operating Environment Precautions ! Caution Do not operate

Application Precautions 5 ! Caution Failure to abide by the following precautions could lead to faulty operation of the Link Adapters or the system, or could damage the Link Adapters or the system. Always heed these precautions. Observe the following precautions when using the Link Adapter system. • Tighten the screws on the terminal block of the AC Power Supply Unit to the torque specified in the operation manual. The loose screws may result in burn- ing or malfunction. • Fail-safe measures mus

SECTION 1 Introduction This document is designed to introduce the reader to the principles of Link Adapters and Repeater Units. Link Adapters and Repeater Units are connecting devices for SYSMAC C-Series Programmable Controllers. Link Adapters are used to interconnect system devices such as host computers, PC Link Units, Host Link Units, and Remote I/O Units, and/or to convert back and forth between wire cable and optical fiber cable. 1-1 Nomenclature . . . . . . . . . . . . . . . . . . . . . .

General Specifications Section 1-4 1-3 Repeater Units Repeater Units are used when the number of Optical Transmitting I/O Units, Op- tical Slave Racks, etc., connected in series exceeds 32. Insertion of a Repeater Unit after the 32nd Unit allows the connection of additional Units. The following Repeater Units are used with the cables shown here: Model Applicable Cables 3G2A9-RPT01-P APF/PCF 3G2A9-RPT01 PCF APF: All-plastic optical fiber cable PCF: Plastic-clad optical fiber cable 1-4 General Spe

RS-422 and RS-232C Cable Section 2-2 2-1 Power Supply and Cable Lengths Power Supply For all but AL001 Link Adapters, connect the AC hot line to the common terminal of the Link Adapter. A fuse is internally connected to the common line. Cable Lengths Maximum length for RS-232C cable is 15 m. For RS-422 it is 500 m, with a maxi- mum of 10 m for any given branch line. For RS-485 cable it is 200 m. Maximum lengths for optical fiber cables connected to Link Adapters are deter- mined by the type of c

Backup Power Supply Section 2-5 When total transmission loss from the system is subtracted from the transmit/re- ceive differential of the Link Adapters, the margin must be at least 4 dB. To deter- mine total transmission loss, first calculate the loss over the cable by multiplying the loss/km by the total length of the cable. Then calculate the loss at the con- nections by multiplying the loss/connection by the number of connections. Final- ly, add the cable loss and the connector loss. Subtrac
