This connector shares the functions TMDS and GPIO. Only one function is
available at the same time and is board specific.
Serial Interfaces COM1 (P2200, P2100) and COM2 (P2201, P2203)
The VR11 offers two RS232 serial ports. All COM ports are accessible via the
transition module at 10 pole headers and are software selectable for RS-232 or
RS-422/485 operation.
Important note:
COM1 is accessible via an RJ45 type front panel connector (P2200) and via
other connectors at the rear. The front panel connector has only 8 pins. It does
not support the Ring Indicator (RI) on RS232 and it does not support
RS422/485 because it is missing RXD- (negative Receive Data). RS422/485 is
available only on rear connections.
The RS485 output drivers can be enabled or disabled with the DTR signal. An
active DTR means the driver are always enabled. When using RS422 setting
the output drivers are always enabled and the DTR signal is not used. COM1
and COM2 are also available at the rear panel with 9 pole D-sub connectors.
