Page 12: Hardware Assembly
ARDWARE SSEMBLY The VL-EPMs-U1 comes in a variety of configurations that use SUMIT-A only, SUMIT-A and SUMIT-B, and PC/104 (ISA) connectors. The module can be added to the middle or top of the stack, above any SUMIT boards and below any PC/104 boards. -
Page 13: Stacking Restrictions
A maximum of two VL-EPMs-U1 boards are supported in the stack. When two VL-EPMs-U1 boards are in the stack, one must be configured with a base address of 0x4E. The other board must be configured to 0x162E or 0x164E. Address 0x2E is reserved for the CPU board's Super I/O. -

Page 22: Gps And Antenna
ONNECTOR A Trimble GPS antenna, VersaLogic part number VL-CBR-ANT02, is available for GPS- enabled models of the VL-EPMs-U1. The antenna has a 5-meter cable and male SMA connector. ATTERY The GPS receiver option provides a battery for back-up (BBU) power to keep the module's RAM memory alive and to power the real-time clock when the receiver's prime power is turned off. - Page 23 When using the TSIP protocol to change port assignments or settings, confirm that your changes do not affect the ability to communicate with the receiver (e.g., selecting the PC COM port settings that do not match the receiver’s, or changing the output protocol to TSIP while not using iQ_CHAT).

15 seconds, the receiver will normally re-establish track within two seconds. If the lost signal is not re-acquired within 15 seconds, the receiver initiates a broader frequency search. The receiver will continue to search for the satellite until it falls below the elevation mask. VL-EPMs-U1 Reference Manual... -
