Introduction C h a p t e r TCC-100/100I is an RS-232 to RS-422/485 media converter. Note that TCC-100I comes with 2 KV isolation protection. The following topics are covered in this chapter: Overview Product Features Package Checklist Product Specifications... -
Page 6: Overview
Moxa TCC-100/100I User’s Guide Overview Introduction Many important devices used in today’s industrial environment are still designed for use with an RS-232 interface. The reason is due in part to tradition, and in part to convenience. RS-232 hardware is relatively easy to design, and the device can be readily connected to most PCs. - Page 7 Introduction RTS/CTS RS-422 Handshaking Signals TCC-100/100I provides RS-422 handshaking signal support. The RTS and CTS signals help solve the RS-422 signal handshaking problem and reduce data transmission errors. Built-in RS-485 ADDC™ Intelligence ADDC™ (Automatic Data Direction Control), a Moxa leading technology, uses a clever hardware solution to manage RS-485’s data flow control problem.

- Page 15 NOTE: TCC-100/100I provides reverse power protection. I.e., it will automatically detect which power wire is negative, and which is positive. STEP 3: Wire the Terminal Block There are three wiring options available for connecting to TCC-100/100I’s RS-422/485 terminal block. 2-wire RS-485...

Page 17: Termination Resistor Diagram
Installation Termination Resistor Diagram Termination is designed to Termination Resistor: mitigate noise from the S3 On to Enable S3 Off to Disable RS-422/485 transmission signals. If the network cable is too long, undesirable transmission-line effects will RxD+ arise. The best method for mitigating energy on an unused RxD- conductor is to dissipate the... -

Typical Applications RS-485 Application A typical RS-485 application for TCC-100/100I is depicted in the following figure. In this scenario, two TCC-100I units are used to connect two PCs to an RS-485 network. The third TCC-100I is used to connect the PLC—which is designed for the RS-232 interface—to the RS-485 network. - Page 19 Installation RS-422 Application A typical RS-422 application for TCC-100/100I is depicted in the following figure. In this scenario, two TCC-100I units are used to create a point-to-point connection between a PC and Scales. The advantage of using two TCC-100I units to convert from RS-232, to RS-422, and then back to RS-232, is that the RS-422 cable connecting the two converters can be up to 1.2 km in length (this is quite an...
