Chapter 2 Installing the Remote Annex 4000
Remote Annex 4000 Serial Cables
The Remote Annex 4000 asynchronous serial interfaces conform to
RS232 specifications. However, it is possible to exceed the
specifications’ cable limits given good quality cables that are run in
an electrically quiet environment. Xylogics only guarantees operation
with the cable lengths recommended below (see
Table 2-2).
The Remote Annex 4000 can incur damage if the cables are hit
by lightning.
Table 2-2. Recommended Cable Lengths
If you exceed these recommended cable lengths, you must
compensate for any resulting electrical problems. Exceed these
distances at your own risk.
