Technical Description
Sealevel Systems ACB-MP.PCI Page 2
Technical Description
The ACB-232.LPCI utilizes the Zilog 85230 Enhanced Serial Communications Controller (ESCC). This chip
features programmable baud rate, data format and interrupt control. Refer to the ESCC Users Manual for details on
programming the 85230 ESCC chip.
Features
•One channel of synchronous or asynchronous communications using the Zilog Z85230 chip
•EIA/TIA-232 Signals supported TD, RD, CTS, RTS, DCD, DSR, DTR, TXC, RXC, TSET, RI
•Programmable options for Transmit clock as input or output
•Software programmable baud rate
Internal Baud Rate Generator
The baud rate of the ESCC is programmed under software control. The standard oscillator supplied with the board is
7.3728 MHz. However, other oscillator values can be substituted to achieve different baud rates.
I/O Registers Definition - Control and Status
The control and status registers occupy 16 consecutive locations. The following tables provide a functional

DSROUT DSROUT – 0 = DSR not routed to SCC 1 = DSR routed to SCC DCDB (0 on power up)*
RIOUT RIOUT – 0 = RI not routed to SCC 1 = RI routed to SCC CTSB (0 on power up)**
TXOUT TXOUT – 0 = TXD routed from SCC to 1488 1 = Forces TXD always a high (for idle mark bug in ESCC)***
Base +14 and 15
SD0-SD15 Optional security feature. Unique value per customer or application. ( default value = FFFF)
* DSR- is connected to Port B DCD on the 85230 only when this bit is set to a 1. If 9015 compatibility is
required, this bit must be set as part of the SCC initialization.
** RI- is connected to Port B CTS on the 85230 only when this bit is set to a 1. If 9015 compatibility is required,
this bit must be set as part of the SCC initialization.

RI- is connected to Port B CTS on the 85230 and the enable bit is set in Base+6.
DSR- is connected to Port B DCD on the 85230 the enable bit is set in Base+6.
Technical Note: Please terminate any control signals that are not going to be used. The most common way to do this
is connect RTS to CTS and RI. Also, connect DCD to DTR and DSR. Terminating these pins, if not used, will help
insure you get the best performance from your adapter.

Appendix A - Troubleshooting
The Sealevel Software is supplied with the Sealevel Systems adapter and will be used in the troubleshooting
procedures. Using this software and following these simple steps can eliminate most common problems without the
need to call Technical Support.
1. Identify all I/O adapters currently installed in your system. This includes the on-board serial ports, controller
cards, sound cards etc. The I/O addresses used by these adapters, as well as the IRQ (if any) should be
identified.
2. Make sure the Sealevel Systems adapter is securely installed in a PCI slot.
3. Use the supplied software and User Manual to verify that the Sealevel Systems adapter is configured correctly.
4. Windows users can use the installed programs in the SeaMAC folder to verify operation.

Appendix C - Electrical Interface
Sealevel Systems ACB-MP.PCI Page 7
Appendix C - Electrical Interface
RS-232 Or EIA/TIA-232
Quite possibly the most widely used communication standard is RS-232. This implementation has been defined and
revised several times and is often referred to as RS-232 or EIA/TIA-232. It is defined by the EIA as the Interface
between Data Terminal Equipment and Data Circuit- Terminating Equipment Employing Serial Binary Data
Interchange. The mechanical implementation of RS-232 is on a 25-pin D sub connector. RS-232 is capable of
operating at data rates up to 20 Kbps at distances less than 50 ft. The absolute maximum data rate may vary due to
line conditions and cable lengths. RS-232 often operates at 38.4 Kbps over very short distances. The voltage levels
defined by RS-232 range from -12 to +12 volts. RS-232 is a single ended or unbalanced interface, meaning that a
single electrical signal is compared to a common signal (ground) to determine binary logic states. A voltage of +12
volts (usually +3 to +10 volts) represents a binary 0 (space) and -12 volts (-3 to -10 volts) denotes a binary 1 (mark).
The RS-232 and the EIA/TIA-574 specification defines two type of interface circuits, Data Terminal Equipment
(DTE) and Data Circuit-Terminating Equipment (DCE). The Sealevel Systems adapter is a DTE interface.
