The SBC-R9 has eight analog inputs with an effective bandwidth of 1.23 kHz divided across all eight analog inputs. The A/D device specifies a maximum…
What bit order does the Zilog 16C32 chipset use for transmitting serial data?
The Z16C32 operates similar to a UART and transmits the least significant bit first. The only exception is when the card is operating in…
Can the BERT pattern be used at data rates above 14.4 Kbps?
The ITU document O.153 paragraph 2.1 indicates the BERT pattern can be used at data rates up to 14.4 Kbps. However, the Sealevel WinSSD…
What CRC-CCITT value is used by Sealevel synchronous serial adapters with the Zilog Z85230?
The CRC-CCITT polynomial value used in the Zilog Z85230 is: x16 + x12 + x11 + x10 + x8 + x3 + x2 +…
What CRC-CCITT value is used by Sealevel synchronous serial adapters with the Zilog Z16C32?
The CRC-CCITT polynomial value used in the Zilog Z16C32 is: x16 + x12 + x5 + 1 The corresponding hexadecimal value is 0x1021.
What is a CRC in synchronous serial communications?
The Cyclic Redundancy Check (CRC) is a check value used to detect transmission errors in a frame or block of data. The transmitter encodes…
Is synchronous mode the only mode that can use a BERT pattern?
Section 2.5 of the ITU O.151 document basically states that a pattern can be encapsulated by the framing bits of a protocol, if necessary.…
What kind of output is best for controlling the power to a DC motor?
Open-collector outputs with circuit protection are the best choice for controlling power to devices with highly inductive loads such as DC motors, solenoids, and…
How will my Sealevel synchronous serial adapter appear in Windows Device Manager?
In Windows Device Manager, Sealevel synchronous serial adapters will install under the “SeaMAC Device” category. The device names for Sealevel synchronous serial adapters, with part…
