Page 3: Before You Get Started
Before You Get Started What’s Included The ACB-V is shipped with the following items. If any of these items are missing or damaged, please contact Sealevel for replacement. ACB-V (P/N: 4012) • Advisory Conventions Warning The highest level of importance used to stress a condition where damage could result to the product, or the user could suffer serious injury. -
Page 4: Installation
Installation The ACB-V can be installed in any of the PC expansion slots. Remove the PC case, remove the blank metal slot cover, and insert the board. Replace the screw, replace the cover, and the installation is complete. Be sure to set the address and jumper options before installation. -
Page 5: Card Setup
Card Setup Address Selection The ACB-V occupies 8 consecutive I/O locations. A dip-switch (SW1) is used to set the base address for these locations. Be careful when selecting the base address as some selections conflict with existing PC ports. The following table shows several examples that usually do not cause a conflict. - Page 6 Option Selection The ACB-V contains several jumper straps which must be set for proper operation. E2- This header selects DMA mode of operation. Channel A of the SCC can operate in either half-duplex or full duplex DMA mode. Full duplex DMA can transmit and receive data simultaneously. Half-duplex DMA can transmit or receive data, but not in both directions simultaneously.
- Page 7 WAIT/REQ A DMA Ch.1 Transmit Data DTR/REQ A Channel B of the ACB-V does not support full duplex DMA. Figure 5 E3: This header selects the interrupt request line for the port. The diagram below shows IRQ 5 selected in a shared configuration.
- Page 8 The factory default setting for E3 is: “5” and “M”. EPROM Usage The EPROM socket on the ACB-V is provided for convenience only and does not affect the communication functions of the board in any way. If the EPROM is not used, the socket should be disabled (dip-switch SW2 position 5 off).

Page 9: Technical Description
24 data, clock, and control signals. The physical connector is defined in the ISO-2593 standard. CCITT V.35 is implemented with both DTE and DCE interfaces, the ACB-V is implemented using the DTE interface. The ACB-V will not generate a clock signal without a modification. because the CCITT V.35 specification does not specify a clock output signal for a V.35 DTE. -
Page 10: Programming The Acb-V Control/Status Port
Programming the ACB-V Control/Status Port The ACB-V occupies eight Input/Output (I/O) addresses. The first four are used by the SCC chip, while the fifth address (Base+4) is the address of the on-board Control/Status Port. This port is used to set the Data Terminal Ready (DTR) signal, to enable or disable DMA under software control, and to monitor the Data Set Ready (DSR) input signals from the modem. - Page 11 4.9152 MHz. However, other oscillator values can be substituted to achieve different baud rates. P1 and P2 Connector The connector on the ACB-V is a DB-15. This connector is matched with a V.35 cable to provide the proper mechanical connection as required by the ISO-2593 standard.
