The 5402e is a PCI Express synchronous serial interface that provides four ports individually configurable for RS-232, RS-422, RS-485, RS-530, RS-530A or V.35. Designed using the popular Zilog Z85230 Enhanced Serial Communication Controller (ESCC), the synchronous serial adapter is an ideal solution for military, satellite, radar, banking and other applications that require robust synchronous communications.

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 on each port, and the board supports data rates up to 128K bps in burst mode. For easy implementation, a fan-out cable is included that terminates the on-board 100-pin SCSI-style connector to four DB-25M connectors. 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.
