GW1500-DH485A: Multi-Protocol Gateway $1,395 USD list

Ascii to DH-485 Network (DH-485 Ascii)

The DataLink GW1500-DH485A is a compact, DinRail ASCII Gateway to A-B DH-485 network protocol. It provides an ASCII interface to PLC’s on the DH-485 Network for printers, bar code scanners, and other ASCII devices.

In Scanner operation the ASCII data is stored in the buffer until either a terminating character (CR, LF, CR & LF) or 240 bytes are received. The packet of ASCII data is then sent to an integer file in the PLC.

In Printer operation, data stored in PLC ASCII files can be outputted to printers or message displays with a simple write command to the GW1000.

The GW1500 can be converted between several protocols with an easy firmware change (ie. DF1, ASCII, Modbus, ModTCP, AB Ethernet, Ethernet/IP) to multiple DH+ /DH-485 nodes.  You may wish to program via RSLINX (AB Ethernet driver) remotely over Ethernet with our GW1500-ABEIP firmware or switch to RSLINX (1770-KF2) serial DF1 to DH+ using our GW1500-DHP1 firmware.
