Connecting ECR in Tailgate Mode
To connect an ECR to the MX 900 Series terminal, insert the multiport cable plug
into the bottom socket on the terminal and install the retainer. Then connect
the RS485 tailgate connector to the desired 12-volt port on the back of the IBM
register, such as 9A or 9B.
Caution: Use caution because the various ports on the back of the register
have different voltages. Plugging into the wrong port may damage
the register or the MX 900 Series terminal.
