ACM/16, ACM/16RJ or ACM/Flex

Note:

1.The ACM/Flex16 with RS-232 and/or 20mA Current Loop interfaces only requires the connection of one external power supply for every 48 ports connected to a HOST Adapter.

2.The ACM/Flex16 with RS-485 only or a combination of RS-232 and RS-485 and 20mA Current Loop interfaces requires the connection of one external power supply for every 32 ports connected to a HOST Adapter.

3.Please install all the metal straps provided to insure a proper connection between ACM/16/16RJ/Flex16 modules. You should install these straps between both the top and the bottom of the ACM/16/16RJ/Flex16 modules. Failure to do so will cause an intermittent connection that will disrupt communications.
