2.3.7 Serial ASYNC Data, Monitor and Control of unit
Two serial ports (SERIAL 1 and 2) for data to/from the unit have the following characteristics:
Table 5. Serial ASYNC Port Requirements
Parameter Specification
Signal Type Serial Asynchronous Character Data
Levels RS-232
Mode Always 8 data-bits, one start, one stop-bit, half-duplex.
Pin-outs DCE to AT-compatible serial port, 3-wire subset (Rxd,
Txd, and Ground) without handshake lines
2.3.8 Option Modules for Expansion Ports
The unit has one expansion slot, which can be used as a high-speed or low-speed slot. Using it
as a high-speed expansion port provides the transport layer multiplexed stream while using it as
a low-speed expansion port provides the filtered packet data. An I2C bus provides control for
option modules. The specifications for individual modules are included in documentation for the
module.
The RF Switch is not an option when the DVB-ASI Input Card is installed.
2.3.9 AC Power
The unit features a universal-input power supply. AC line power is fed into a standard IEC jack.
The nominal inputs are 115 or 230 VAC ± 10% at 50-60 Hz ± 2%. The total AC current
consumption with max LNB DC load is 0.8A at 115 VAC, and 0.5A at 230 VAC. See Table 1
(Page 13).
