The 5102e is a low profile PCI Express synchronous serial interface that provides a single channel configurable for RS-232, RS-422, RS-485, RS-530, RS-530A or V.35. In RS-232 mode, all common modem control signals are implemented for compatibility with a wide range of peripherals. A digital phase lock loop (DPLL) is included and the board supports data rates up to 128K bps in burst mode.

Designed using the popular Zilog Z85230 Enhanced Serial Communication Controller (ESCC), the synchronous serial adapter is an ideal solution for applications including DDS (digital data service), military applications, banking communications, and other specialized applications. Our Software toolkit is included to aid software driver development for other operating systems by providing programming samples and source code to shorten development time. Terminal blocks, adapter cables, and other helpful accessories are available to simplify installation.

Software support, critical for successful synchronous communication development, is provided through Sealevel’s SeaMAC synchronous serial driver. HDLC/SDLC protocols are supported as well as certain configurations of Monosync, Bi-sync, and Raw modes.

The 5102e is compatible with any low profile PCI Express slot. A standard profile bracket  is also included.

    5102E review
    We started using Sealevel products in 1997 when we had a requirement to implement a SS7 driver in a PC. The excellent support and documentation we received from Sealevel enabled us to easily complete the project and we have used Sealevel HDLC cards ever since. We have a number of 5102s deployed so with the hardware aging and new hardware only supporting PCIe we were pleased to find that Sealevel now has a PCIe solution. We got some 5102e cards and thanks to your excellent tech support were able to modify our driver to work with the new card in quickly. Sealevel’s product support has always been excellent which is why we use your products in the servers we build for our customers.
