 |
| ||
| Serial Protocol: | |||
|
Your choices are... |
| ||
|
RS232 |
RS232 is a serial, binary-data interface between data terminal equipment (DTE) and data communications equipment (DCE). | ||
|
RS422 |
RS422 is a balanced serial interface (greater noise immunity) for the transmission of digital data. It was designed for greater distances and higher baud rates than RS232. | ||
|
RS485 |
Like RS422, RS485 is a balanced serial interface for the transmission of digital data. The difference between RS422 and RS485 is that RS485 can be transformed into a multi-point application. | ||

|
|
| ||
| Card Form Factor: | The form Factor describes the size of the card and its pin configuration. | ||
|
Your choices are... |
| ||
|
Type I Card |
Type I cards are 54 mm x 85.4 mm, and can be up to 3.3 mm thick. They are commonly used are used as memory cards (RAM, ROM, Flash RAM, etc.). | ||
|
Type II Card |
Type II cards are 54 mm x 85.4 mm, and can be up to 5.5 mm thick. They are commonly used in I/O devices such as data/fax modems, and in LAN adapters and non-rotating mass storage devices. | ||
|
Type III Card |
Type III cards are 54 mm x 85.4 mm, and can be up to 10.5 mm thick. They are commonly used as hard drives. | ||
|
Type IV Card |
Type IV cards have not yet been ratified by the PCMCIA consortium; however, their size is expected to be 54 mm x 85.4 mm with a thickness of 18 mm. They will be used in large capacity hard drives. | ||

|
|
| ||
| Number of Channels: | This is the number of ports available. PCMCIA cards can have one or more independent serial interfaces, or they can have a dual interface (i.e., RS232 and RS422) with only one physical port. In this latter case, a switching mechanism allows the user to select the type of protocol. | ||
|
Your choices are... |
| ||
|
One Channel |
The card has only one independent port. | ||
|
Two Channels |
The card has two independent ports, each one with its own cable and connector. | ||
|
Four Channels |
The card has four independent ports, each one with its own cable and connector. | ||
|
Other |
Other unlisted number of channels. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Serial Connector Type: | |||
|
Your choices are... |
| ||
|
DB-9 |
DB-9 connectors are 9-pin, D-type connectors. | ||
|
DB-25 |
DB-25 connectors are 25-pin, D-type connectors. | ||
|
Other |
Other unlisted connectors. | ||

| |||
|
Data Transfer Rate |
The data transfer rate is a unit of signaling speed that specifies the number of signal elements (baud) that can be transmitted per second. If a signal element represents one bit of information, then the baud rate is equivalent to the bit rate (bits/sec). In general, however, a baud translates into more than one bit/sec. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||

|
Operating Temperature |
This is the full-required range of ambient operating temperature. | ||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
| |||
|
CE / FCC Certified? |
The card bears the European Union's CE Mark, or is certified by the U.S. Federal Communications Commission (FCC). | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
