1 out of 5 eggsNOT RS-232 to RS-422

Pros: The pin assignments are molded into the black body.

Cons: It LOOKS like an RS-232 to RS-422 adapter, but it isn't.
(The price should have been a clue.)

As to "Meet Indsutrial Standards" it cannot because there are NO standard RS-422 pin arrangements for DB9 plugs.
It probably matches StarTechs RS422 adapters (ICUSB422, etc.), but I would check other
manufacturers' datasheets.

1 out of 5 eggsWish I had known the pin-out beforehand

Pros: Solid construction. Meets Industrial standards.

Cons: Pin-out is fixed and unchangeable, see notes below. Could not find diagram anywhere on the manufacturer's page. There are several standards of RS485/422 over DB9 and not having a pin configuration listed is unacceptable. For this reason I'm giving this product one egg.

Other Thoughts: Searched high and low for a pin configuration before I purchased this. Unable to find one (even on the manufacturer's data sheet) I bought one of these hoping it would match the standard that my PLC uses. It didn't. This product has the following pin configuration:

T+/D+ : Pin 2
T-/D- : Pin 1
R+ : Pin 3
R- : Pin 4
GND : Pin 5

Unfortunately it doesn't do me any good but hopefully this review helps someone else.
