VIII. CABLE CONNECTION
1. CHANNEL A
RJ-45 Modular Type Cable Information
Please use the straight LAN cable (shielded type) which is generally sold.
RS422/485 Shielded Twisted Pair
Conductor: AGW24
Characteristic impedance: < 100 ohms
Capacitance per meter: 40 - 100 pF
Attenuation at 1Mhz / 100m: 2 - 6 db
Cable length: max. 1200 m
Connectors and Connector Shells: Ideally use: EMI / RFI Shielding RJ45 type
About Ground
Each ECR must be grounded at the same level and the termination resistors must be fitted on the first and last
devices on the line. Please refer to the document "IRC & TERMINAL PRINTER CABLING INSTRUCTION
(RS485)" for how to connect cables.
Joint Box
JOINT BOX 485 (REF.# 62092) makes the cable connection simple, quick, and easy between ECRs and
Terminal Printers on an IRC line (RS485). Refer to the option instruction manual for details and connection
samples.
