ACB-MP.PCI User Manual 
Introduction 
The ACB-MP.PCI adapter provides the PC with a single channel multi-protocol 
serial interface utilizing the Zilog Z85230 (ESCC™), which supports HDLC/SDLC 
protocol using the Sealevel SeaMAC V4 device driver. SeaMAC V4 also supports 
certain configurations of monosync, bisync, and raw modes. The ACB-MP.PCI 
adapter is an ideal solution for applications including DDS (digital data service), 
military applications, banking communications, and other specialized applications. 
The ACB-MP.PCI also utilizes the Sipex-505 multi-protocol electrical interface chip 
that allows the ACB-MP.PCI to be compliant with EIA/TIA-530/530A, EIA/TIA-
232E, EIA/TIA-485, and ITU V.35. Optional cables are available to connect RS-
449, RS-530, RS-530A, V.35 and X.21 interfaces.
