Hi Sirs,
As title, we have use TRS3243E.
We need confirm does TRS3243E support EIA423 signal??
Have any risk??
Thanks for your help.

Shu-Cheng,
The drivers should be compatible, but the receivers have the wrong thresholds.
Sam,
TRS3243E RS232 drivers and standard RS422 receivers could work.
However the RS232 drivers can't handle the minimum 450 ohms load.
Here is some basic information including RS232 and RS423

Hi Ron,
Thanks for your reply.
Please let me to summarize.
Actually our end customer device are DECserver 700 manx.classiccmp.org/.../dsrvwmgb.pdf
There are two module (700-08/700-16) (page 12.13)
The DECserver 700-08 supports EIA-232-D/V.24/V.28 full modem control on eight 25-pin male D-connectors. Use this model to connect devices that require full duplex, asynchronous control (for example: modems).
The DECserver 700-16 supports EIA-423-A and DEC 423 data-leads on 16 MJ8 connectors. Use this model to connect devices requiring data-leads for operation
For now we use TRS3243E at 700-08. TRS3243E spec looks OK. Could you help double confirm i'm correct??
Actually we would like use TRS3243E at 700-16 to support EIA-423-A and DEC 423, so we ask TRS3243E support EIA423??
But i think i'm wrong because for EIA-423 spec, the max load could support to ten devices and cable could support to 1200m.
Looks TRS3243E couldn't do it, Right??
So i'll use DS3691+DS3486 to do it .
Please tell us if i'm wrong. Many thanks for your powerful help.
