The Sealevel Systems ACB 530 provides the PC with two high-speed Synch/Asynch links to devices requiring extremely high data rates. RS-530 is a replacement for RS-449 in telecom applications and defines a standard DB-25 pin-out. The ACB 530 is capable of RS-530, RS-422/485 or RS-449 (with optional cable) connections. The ACB 530 card has a maximum data rate in excess of 1 million bps. The ACB 530 supports simultaneous full duplex DMA transfer on both channels. The Sealevel ACB DOS Developer's Toolkit is included along with SeaMAC, DOS SDLC Media Access Control Driver, to shorten development time. SeaMAC Windows Drivers are also included supporting various protocols. Check out our ""Getting Started with ACB Synchronous cards"" guide to get up and running quickly. |
