Computer or PLC can be either 422 or 232 communications.
Connections for 422 communications:
J22 on filter card should be jumpered across pins 2 and 3.
The cable coming from the EIC card plugs into J2 and J3 on the filter card.
The connector with the black and green wires plugs into J2 with the black wire on in 1 of J2.
The connector with red and white wires plugs into J3 with the white wire on pin of J3.
The connector for computer hook-up is J1.
Connections for 232 communications:
J22 on filter card should be jumpered across pins 1 and 2.
The cable from the EIC card plugs into J2 and J3 on the filter card.
The connector with the black and green wires plug into J3 with the green wire on pin 1 of J3.
The connector with red and white wires plug into J2 with the red wire on pin of J2.
The connector for computer hook-up is J4.
2.
J14 is the connector for the sine-cosine resolver input.
Refer to drawing B10W996-1 for wiring detail.
3.
There is a 422 to TTL converter on the card. 422 plugs into J8 and the TTL connects to J9.
The normal operation of J19 should be jumpered across pins 2 and 3.
4.
There is another port which can be either TTL to 422 or TTL to 232. The TTL plugs into J11. For
normal operation, J20 will be jumpered across pins 2 and 3. The standard set-up will be for TTL
422 communications with U6 installed and U7 removed. In order to have TTL to 232, you must
install U7 and remove U6.
5.
J12 is the user connector for LDT and analog resolver connections. J17 is the connector for +
and 15v power to LDT's.
6.
There are two cables which plug into J16 and J18 on the card. These two cables are power for the
filter card. J16 is + and -15v. J18 is +5v and ground.
For normal 422 communications, the following settings apply:
J19 jumpered between pins 2 and 3
J20 jumpered between pins 2 and 3
