OSM-1000-BRD Quick Start Guide
OSDP-Wiegand Converter
Product Overview:
The OSM-1000-BRD (board only) OSDP-Wiegand Converter is a general purpose Wiegand / OSDP converter. The OSM unit has two
operating modes, PD (Peripheral Device) mode and ACU (Access Control Unit) mode. In PD mode, the OSM unit connects a
traditional Wiegand reader to an OSDP ACU. In ACU mode, the OSM unit connects an OSDP reader to a traditional Wiegand Access
Controller. Additionally, two OSM-1000 units can be used together, one in ACU mode and the other in PD mode, to connect a
Wiegand reader to a Wiegand Access Controller with an OSDP connection in between.
What is included:
☐ OSM-1000-BRD (board only) ☐ Warranty ☐ Quick Start Guide
Pin Designations:
DIP Switch Settings:
DIP Switches 1-4: Set the OSDP Polling
Address in PD mode. Set the OSDP Address
to be polled by the OSM unit in ACU mode.
See the DIP Switch Address Table to the right.!
DIP Switch 5: When ON, enables the Beep on
Read feature when in ACU mode.!
DIP Switch 6: When ON, enables Secure
Channel communication. !
DIP Switch 7: When ON, inverts osdp_LED
command sent to PD when in ACU mode; and
inverts the state of the output pin based on
osdp_LED command received in PD mode. !
DIP Switch 8: When ON, the OSM-1000 is set
to ACU mode. When OFF, the OSM-1000 is
set to PD mode.

Status LED Behavior:!
The OSM-1000-BRD unit has a tri-color LED that can display red, green, blue, and white. The startup sequence lasts approximately
5 seconds and the LED will display red, blue, green, white or display red, green, blue, white. !
ACU Mode:!
Communication with PD: the status LED will be blue with fast, green flashes or green with fast, blue flashes. The status LED will
briefly turn red when it receives reader data from the PD.!
No Communication with PD: the status LED will be blue with slow, green flashes or green with slow, blue flashes. The status LED
will briefly turn red when it receives reader data from the PD.
PD Mode:!
Communication with ACU: the status LED will red with fast, blue flashes or red with fast, green flashes. !
No communication with ACU: the status LED will slowly fade from red to off, and back to red.
Bench Testing: Bench testing is recommended to avoid troubleshooting issues in the field.
ACU Mode:!
1. At the bench, connect the OSM unit to the PD and the Wiegand access controller by following the ACU Mode Wiring Diagram.!
2. Observe the OSM unit and PD communicating. Refer to the “Status LED Behavior” section to verify that the OSM unit is
communicating with the PD.!
3. If the devices do not communicate, make sure the the baud rate and polling ID match. In the OSDP spec, the default baud rate
is 9600 and the default polling ID is 0.!
PD Mode:!
1. At the bench, connect the OSM unit to the Wiegand reader and ACU by following the PD Mode Wiring Diagram. !
2. Observe the OSM unit and ACU communicating. Refer to the “Status LED Behavior” section to verify that the OSM unit is
communicating with the ACU. !
3. If the devices do not communicate, make sure the the baud rate and polling ID match. In the OSDP spec, the default baud rate
is 9600 and the default polling ID is 0.
