Some Benefits of the 5259 Automatic Converter:
Saves Time:
- No computer required for setting up. Complete setup with one
switch.
- Switchable line termination.
- Automatic baud rate detection.
High Performance:
- Selected channel receives only data intended for it. No leakage
of channel selection characters.
- Very fast data turnaround. For 8 bit no parity: 0.2ms at 9600bps
- Communication distance of up to 1.2km (4000 feet)
Versatile:
- Small size 1" wide (25.4mm), light-weight unit.
- Mounts on all DIN types (15mm or 35mm top hat) and G type asymmetric.
- 9 - 24 volt power supply
- Works with PC and PLCs.
- Can handle binary data.
- Broadcast mode allows sending data to all RS-232 devices on network
at one time.
Easy to Install:
- Plugs directly into your PC serial port.
- Plug in screw terminal connector for RS-485.
- Separate transmit and receive lights show data flow. Address
light shows when unit selected.
Safe:
- Full optical isolation protects your computer from power spikes.
- RS485 side has self resetting fuses and spike protection on each line.
- Robust flame retardant case.
- Microprocessor has watchdog protection.

How to use an addressable RS-232 to RS-485 converter.
Have you ever wished to connect more than one RS232 device to your computer
at a time? The addressable RS232 to RS485 converter allows this. Each device
can be individually selected and the computer or PLC talks to that device.
For example, you want your computer to talk to 3 printers in different
parts of the factory. Wire up the 5259 converters as in the picture.
The 5259 connected to printer 1 has its address set to address 1. Similarly
for the 5259s connected to printers 2 and 3.
To select a printer a command is sent. This can be either the STX (02HEX)
control character, or HeAdEr.
The following example sends "Hello World" to printer 1 and "Good Morning" to
printer 2
HeAdEr01Hello World HeAdEr02 Good Morning
The printers only receive the data intended for them and never the command
HeAdEr.
