COM 1 & COM 2
There are 2 COM ports, COM 1 and COM 2, in VPort 2140 Video Server for connecting the
external devices, such as Motorized PTZ controller, Modem, or Multiplexer.
RS-232 RS-485 Speed
COM 1
DB9 Male Terminal block for Data+, Data- Max. 115. 2 Kbps
COM 2
DB9 Male N/A Max. 115. 2 Kbps
Interface mode
The COM 1 supports 2 serial interfaces, although only one interface can be used at a time.
Depending on the interface used by the attached device, administrators must set the Interface
mode to either RS-232 or RS-485.
The COM 2 only supports RS-232 interface. For this reason, there is no interface mode selection
for COM 2.
ATTENTION
RS-232 interface is used via the DB9 COM port, and RS-485 interface is used via the GPIO.
These 2 interfaces cannot be used at the same time.
