Serial Connector - COM

The VX3030 integrates two serial communications ports, COM1 and COM2 in PC parlance. COM1 and COM2
are available via the VPX P2 connector.
COM1 is also available via the front panel connector.
>
COM1: EIA-232/485 (simplified RX/TX) port on RJ-12 front panel connector or on the rear P2 connector
>
COM2: EIA-232/485 (simplified RX/TX) port on the rear P2 connector
Each serial port is configurable via the CPLD as EIA-232 or EIA-485. Each port operates in full duplex mode.
Fast slew rate is the default mode in EIA-485 mode.
The signaling level of EIA-485 is compatible with EIA-422, so full duplex EIA-485 may also be used for point-to-
point communications with an EIA-422 serial port.
Refer to section 4.3.3 " P2 Connector" page 47 for more information on the serial lines wafer assignment on P2
connector.

A serial line should only be used via one connector at the same time, either the Serial front panel
connector or the P2 connector.
