the PCB. The cards that can be used are as follows:

PY-COM Combined network card. Can be configured for use in RS485 and RS422 networks. Automatic

baud-rate selection between low and high speeds (9.8k b.p.s. or 78k b.p.s.).

PY-FTT Compatible with FTT10 (Flexible Topology) 2-wire bus-connected, half duplex. High speed only.

PY-422 Compatible with RS422, 4-wire point-to-point, full duplex. Available in low and high speed variants.

PY-485 Compatible with RS485, 2-wire bus-connected, half duplex. Available in low and high speed variants.

PY-FI7 and PY-FI9 Compatible with dual, multi-mode fibre optic point-to-point connections. PY-FI7 operates at 78k

b.p.s., PY-FI9 operates at 9.8k b.p.s.

If the correct network card is not already fitted, change it using Figure 8 as a guide.

CAUTION

To avoid damaging the module, switch off the power before fitting the network card.
