Introduction
Nowadays, a great number of RS-232 devices for both automation and information transfer
are being used in industrial applications, and linking these devices is very important in the
modern situation. The devices are usually located at a distance from the Host PC, meaning
that linking via multiple serial cards is inefficient. ICPDAS tM-752N series products have been
developed to provide an effective link between multiple RS-232 devices via a single RS-485
network. This network protocol offers stability, reliability and simple cabling while delivering
a low–cost, easy-to-maintain product.
To achieve maximum space savings, the tM-752N is offered in an amazingly small form-
factor that enables it to be easily installed anywhere, even directly attached to a serial
device or embedded into a machine. The tM-752N features a powerful 32-bit MCU, offers
true IEEE 802.3af-compliant (classification, Class 1) Power-over-Ethernet (PoE) functionality
using a standard category 5 Ethernet cable that allows it to receive power from a PoE switch
such as the NS-205PSE. If there is no PoE switch available on site, the tM-752N can accepts
power input from a DC adapter.
