General Installation and Setup
1. The M1XSP operates on the M1's Keypad data bus and may be remotely located near the equipment to which it is
interfacing. Two (2) #6 x 1/2" screws (not provided), one on each side of the black box should be used. It can also be
mounted inside the M1 cabinet using the same method OR by removing the board from the black box and installing the
board into a pair of ELK-SWG Plastic Glide brackets.
2. Before making any wiring connections, turn Off the M1 Master Power Switch.
3. Connect terminals +12V, A, B, and Neg from the M1XSP to the M1's Keypad Data Bus (terminals +VKP, Data A, Data B, &
Neg).
NOTE: Refer to the M1 Installation Manual and the M1DBH information in this manual about proper
connections of data bus devices with multiple homerun cables.
4. There are 4 address switches, each with a position of OFF or ON (binary value 0 or 1) and a decimal equivalent value of
(1, 2, 4, or 8). The total decimal value of the "ON" switches equates to the data bus address. As a rule, the first M1XSP
should be set to address 1. If more than 1 M1XSP is installed, set each one to a unique (sequential) address (2, 3, etc).
IMPORTANT: When interfacing with HAI Thermostats, address switches on the M1XSP may ONLY be set to 1, 2, 3, or 4. Address
1 talks with HAI Thermostats addressed as 1 thru 4. Address 2 talks with HAI Thermostats addressed as 5 to 8. Address
3 talks with HAI Thermostats addressed as 9 to 12. Address 4 talks with HAI Thermostats addressed as 13 to 16.
5. Set the Mode jumpers according to the desired application. Refer to the jumper settings table on page 10. If the M1XSP
is being used for a Lighting or Thermostat application the baud rate will be internally fixed according to the mode/protocol.
The baud rate jumpers are ignored UNLESS it is jumpered to be a Serial Port Expander.
