ARX8-2400

ATX8-2400

The ARX8 and ATX8-2400 simplex wireless RS-232 subassem-

blies feature transparent connectivity at 2400bps, 8, N, 1. The RF

communications protocol is taken care of by the on-board micro-

controllers and error checking is automatically performed at the

receiver end, allowing only valid data to be output to the serial port.

Communication status LED’s provide visual confirmation of data

being transmitted and received. Power is supplied via a 9V battery

snap.

The ATX8-2400 includes a convenient jumper enabled TEST LINK

mode. When in this mode a preset 8 byte message will continu-

ously be transmitted. Reception is easily verified by the ARX8 re-

ceiver’s communication LED. A link test may therefore be per-

formed without connecting the modules to any hosts.

The ATX8-2400 transmitter module implements clear to send flow

control (CTS) for use in applications where that require more than

8 bytes of data is to be transmitted. Using the CTS flow control line,

any amount of data may be transmitted.

Features

... Once connected the modules may be powered up. The Green power LED’s will be on. Communication Setup The ATX8 and ARX8 host’s serial ports should be configured for 2400baud, 8 data bits, No parity, 1 Stop bit and flow control set to None. This configuration allows for the ATX8 to transmit up to maximum of 8 bytes per transmis- sion ...
