Introduction and Installation
Introduction
Overview
The ACB-232.LPCI adapter provides the PC with a single channel multi-protocol serial interface utilizing the Zilog
Z85230 (ESCC™), which is suitable for the most popular communication protocols including HDLC/SDLC, X.25,
Bi-Sync, Mono-Sync, and asynchronous.
The ACB-232.LPCI is compliant with EIA/TIA-232E.
What’s Included
The ACB-232.LPCI is shipped with the following items. If any of these items are missing or damaged, contact the
supplier.
• ACB-232.LPCI Adapter
• Sealevel Software
• Standard PCI Profile Bracket
Installation
Operation System Installation
Note: For the5103 to work properly in Windows 2000, Plug and Play OS must be turned off in the BIOS.
Choose Install Software at the beginning of the CD and select Install SeaMAC.
System Installation
The ACB-232.LPCI can be installed in any of the PCI expansion slots.
1. Turn off PC power. Disconnect the power cord.
2. Remove the PC case cover.
3. Locate an available PCI slot and remove the blank metal slot cover.
4. Gently insert the ACB-232.LPCI into the slot. Make sure the adapter is seated properly.
5. Replace the screw.
6. Replace the cover.
7. Connect the power cord.
Installation is complete.

Technical Description
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
description of the bit positions.

SCC interrupt status: 1 = No interrupt pending on IUSC; 0 = Interrupt pending on IUSC.
Base +5
SYNCA _RTS – 0 = SYNCA is high, 1 = SYNCA connected to RTS ( 0 on power up )
SYNCA_CTS – 0 = SYNCA is high, 1 = SYNCA connected to CTS ( 0 on power up )
Base +6
CHAN A – TSET clock source 0 = TRXCA as source, 1= received TXC as source ( 0 on power up )
RXCOPTA – 0 = selects received RXC for RTXCA, 1 = selects SCC PCLK for RTXCA ( 0 on power up )
DSROUT – 0 = DSR not routed to SCC 1 = DSR routed to SCC DCDB (0 on power up)*
RIOUT – 0 = RI not routed to SCC 1 = RI routed to SCC CTSB (0 on power up)**
TXOUT – 0 = TXD routed from SCC to 1488 1 = Forces TXD always a high (for idle mark bug in ESCC)***
Base +14 and 15
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.
