Sealevel Unveils PCI Express Synchronous Serial Interface

By Carolyn J Dawson, TMCnet Contributor


Sealevel has unveiled a PCI (News - Alert) Express synchronous serial interface, 5402e, ideal for use with the well-appreciated Zilog Z85230 Enhanced Serial Communication Controller or ESCC. Military, satellite, radar, banking and other applications needing a sturdy synchronous communications normally prefer the synchronous serial adapter, Zilog Z85230 ESCC.


Sealevel’s 5402e has been built using the maiden 4-port PCIe sync board. The 5402e offers four ports, can be configured independently, for RS-232, RS-422, RS-485, RS-530, RS-530A or V.35.

Each and every regular modem control signals are deployed in RS-232 mode, offering compatibility with a broad assortment of peripherals. A digital phase lock loop or DPLL is incorporated on every port for ensuring highest compatibility with an array of synchronous protocols. A fan-out cable is also incorporated for simplified deployment. This cable connects the on-board 100-pin SCSI-style connector to four DB-25M connectors. Installation is further simplified by offering useful accessories like terminal blocks and adaptors among others.

Sealevel's SeaMAC V5 synchronous serial driver offers software assistance, which is very important for synchronous communication development. This driver is not only compatible with HDLC/SDLC protocols but also with specific configurations of Monosync, Bi-sync and Raw modes. Sealevel has confirmed the availability of all the products, whose starting price is $1,599.00.

Sealevel’s 5402e complies with RoHS and WEEE regulations. The interface supports maximum data rates of 128K bps in the burst mode. All modem control signals are deployed by the interface, which also complies with PCI Express X1. All standard-height PCI Express slots are also compatible with 5402e. 

Sealevel Systems (News - Alert), Inc. was established in 1986 with headquarters in Liberty, South Carolina. The organization not only offers industrial computing solutions, but also provides an assortment of communications and I/O products. These include PCI and PCI Express Bus cards, Ethernet serial servers, USB serial adapters, PCMCIA cards, and PC/104 modules. Multi-port RS-232, RS-422/485, RS-232/422/485 multi-interface high-speed sync/async, and digital/relay I/O are some of the offerings included in Sealevel’s portfolio.

The organization’s design, sales, support and manufacturing units are located at a 45,000 sq. ft. facility in Liberty, South Carolina. The organization has installed more than 15,000 sq. ft of high-tech ESD tiling, thereby preventing damage to electronic equipment due to static electricity.
