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

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
