Connecting the Seam Bridge to DoorKing

Learn how to connect your DoorKing unit to Seam.

The Seam Bridge can be used to connect traditionally offline devices to Seam. This guide will walk you through connecting your DoorKing unit to Seam via the Bridge.
Connecting the Seam Bridge to your DoorKing unit
First, wire the provided 5-pin terminal block to the DoorKing unit’s RS232 header. This can either be done via a DB9 cable (recommended) or directly between the two systems.

Connecting without a DB9 cable
If connecting a Bridge to a DoorKing unit without a DB9 cable, these are the connections that need to be made from the Seam Bridge → DoorKing:
1.GND → GND
2.TX → RX
3.RX → TX
4.RTS → CTS
5.CTS → RTS
Configure your DoorKing unit
The Seam Bridge requires that the unit is configured for 19200 baud rate. This can be done by:
1.Entering * 8 5 <master code>
2.Entering 1 to select 19200
3.Pressing 0 and # together to finish the programming sequence
Connect power and Ethernet
1.Plug in Ethernet
2.Connect power. You can either use the provided 12V DC adapter or connect the Seam Bridge to any 9-36V AC or DC power source.
Connect to Seam
Ask Seam support to enable the Bridge by emailing [email protected] or going to seam.co and clicking the chat icon in the bottom right corner.
