MatchPort b/g Pro Integration Guide 15
Figure 2-10. Separate RS422 Transceivers for 2-Wire and 4-Wire Setups
To protect the MatchPort b/g Pro and circuitry on the target board against ESD at serial
ports, the selected transceiver(s) should have RS232/422/485 bus-pin ESD protection
(typically around 15 KV) either on-chip or by external diode arrays.
IO Configurable Pins (CPs)
There are up to seven CPs if no DTR or DCD is used on the serial ports. All CPs have
internal pull-up resistors, but the value differs. See table.
CPs can be configured for special functions, like DTR, DCD, RS232/RS485 selection or
as general purpose Input or Output (pollable/controllable via CLI or Web Manager). For
more information see the User Guide.
