I-station Update Adaptor without using a RS232/422 converter - See attached.
Instructions on how to make an adaptor to program the I-station and E-station without the use of the RS-422 converter, thus saving money and time to create.
These adaptors were tested with an I-station and an E-station using a 10 foot Ethernet cable and a 6 foot RS-232 extension cable and the results were perfect.
The adaptors cost $2.75 apiece, so for $5.50 plus shipping you can have everything you need to update an I-station. The wiring allows for STANDARD Ethernet cables to be connected to the stations so no custom cabling needs to be made.
