The TR-4800E-BHP designed to work in conjunction with the TR-4800E (+BP16) tally router. This 2RU bulkhead panel takes the GPIOs from the rear DB37 connectors on a TR4800E(+BP16) and then translates the 48 General Purpose Outputs and 32 General Purpose Inputs each to 2 pin terminal blocks. Five 6-foot (2 meter) cables are provided to connect form the TR-4800E to the BHP to allow remote placement of the bulkhead panel. Wet and Dry modes are easily selected for each GPO and GPI via a slide switches and no rewiring required. All GPIO are broken out to 2-pin removable terminal blocks to allow easy wiring. Additionally the BHP has a cable strain relief bar runs across the middle of the panel to provide a tie point for the GPIO cables.
